In bats made of maple wood, like the Axe Bat, it's easy to find the strongest grain. The bat is 84 cm long, and has a mass of 849 gram. The end result can be a greater ball speed off the bat, in the same way that a tennis ball bounces a lot better off tennis strings than off a hard floor. 2 0 obj The wood bat is ultimately the best choice for any player who wishes to use a bat with the most natural power and the fastest speed. The weight drop of a baseball bat is the difference between a bats length and its weight in ounces, which is the difference between a bats length and weight in ounces. /R [52 73 308 791 ] Since it's vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesn't cause the bat to. dKoL!8Ka#EV,@V!\j8ZFbp6EE<9cn=N6j0nf;(&;QU6bUD')c@\ The same thing happens when swinging a golf club, but it is not a well-known effect. During the fraction of a second after the ball hits the bat, the ball compresses as the energy of the motion is absorbed by the ball, causing it to become elastic potential energy. /P 11 0 R This point, usually 5-7 inches from the barrel end, does not move when the bat is vibrating in its first (or fundamental) bending mode. This includes both the length of the barreltop part of the batand its diameter The longer the barrel, generally, the larger the sweet spot for hitting the ball The standard diameter is 2 , and big barrel bats, allowed in some leagues, are 2 5/8. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. A batsman during a cricket game aiming his shot to hit the sweet spot of the bat. A similar result is obtained when swinging cylindrical rods, as described in a paper that can be downloaded here. Each type of wood has its own unique characteristics, making it important for players to consider the type of wood when selecting a bat. /N 24 0 R When selecting a bat for the major leagues, it is critical for players to select the best wood for their bat in order to maximize performance, durability, and longevity. He has been writing about the sport for over five years and is passionate about sharing his knowledge and enthusiasm for the game. /N 16 0 R I have done quite a bit of independent research in both areas. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision. 2. But opting out of some of these cookies may affect your browsing experience. As discussed earlier, missing the sweet spot can cause vibrations in the bat. Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. Collisions.- 11.Bat Performance.- 12.

Sniper Skin carries a line of great bat grips which are easy to install and remove while virtually eliminating the sticky gunk left on your bat. endobj One of these sweet spots relates to vibration. The bat was swung through an axis 143 mm from the knob end. It is almost as easy as walking. Theres one where it feels good in your hands, one where the ball comes off the fastest. /R [316 74 572 585 ] Hitting the "sweet spot" is something that baseball players strive for. However, it will also feel heavier when swung. >> window.mc4wp.listeners.push( There is no simple physics answer to the heavy/light bat question here. But strong vibrations are generated for impacts near the tip. Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. /Width 77 In the late 1990s, the Crisco-Greenwald Cage Study found that bats made out of materials like aluminum perform better, for a number of reasons: First of all, it takes more skill. Its center of mass is 52.6 cm from the knob end. Step up to the batters box and get warmed up for the physics of baseball bats with this, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete, If you have two bats, each with the same weight the bat that carries more weight in the end will perform better in terms of speed. The sound made by a bat can be described as a "ping". The higher the number, the heavier the bat will be, meaning it will have more mass and therefore more power when it makes contact with the ball. >> Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. It would therefore not be surprising if a softball can be pitched at say 1000 rpm. Movies showing the collision of a baseball with a cricket ball and the collision of two billiard balls are shown in the page on collisions. 19 0 obj It was there that he first had the idea to create a resource for physics enthusiasts of all levels to learn about and discuss the latest developments in the field. Its moment of inertia about an axis through its center of mass is 0.184 kg.m^2. When a player has a bad hit and fails to hit the sweet spot, it causes vibrations which can cause the bat to bend or break. If the bat approaches a ball incident at speed vin then. Step up to the batters box and get warmed up for the physics of baseball bats with this great video from ESPN Sports Science. A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. Why dies the bat vibrate inside or outside of the sweet spot? Physicist Daniel A. Russell explains the physics of a baseball swing with a bat. Also,. This cookie is set by GDPR Cookie Consent plugin. The majority of hitters take a stride when hitting, which helps the timing of their swing. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. << This equation for acceleration can , Dry ice is the name for carbon dioxide in its solid state. The sweet spot's location for maximizing how far the batted ball travels after being hit can be calculated scientifically. When you hit the sweet spot, the bat feels the best in your hand. But I would expect there to be a difference.. << Thick walls are also needed to help prevent the walls dinting or cracking. /N 10 0 R The force on the bat can be worked out from the velocity of the center of mass, (CM), and the torques can be worked out from the angular acceleration. The hitch is, no one knows for sure how close the optimal spot for hitting is to the sweet spot that players know and love. 3. Ash bats, on the other hand, are more flexible, making them perfect for contact hitters. The consent submitted will only be used for data processing originating from this website. The ball seems to spin faster when it is fresh and slower after it has been used, but more experiments are needed to determine whether this is in fact correct. endobj It's where the wood grain is strongest. The direction of the centripetal force is toward the center of the circle followed by the path of the CM. Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. 1) Hit with the label up Manufacturers always place the label on the face of the grain. << A great way to keep a rhythm throughout your swing is to step or stride toward the pitcher. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. Pitching Trajectories.- 5. The outgoing speed of the ball is just the sum of the two separate parts - the speed when the bat is at rest plus the speed when the ball is at rest. /N 12 0 R The wake gets deflected depending upon which way the ball rotates. Although most baseball players may not know the deep details, they usually understand that it is not just the skill and effort they put into their swing, but also the specifications of their baseball bat which will impact the success of the hit. 18 0 obj Since little of the bats energy is lost to vibrations when this spot is hit, more can go to the ball. We and our partners use cookies to Store and/or access information on a device. An impact at the fundamental node will not excite that mode, but it will excite the second mode. , 231-232 (2001). The direction of the centripetal force is toward the center of the circle followed by the path of the CM. READ SOMETHING ELSE Table of Contentsshow Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. Bamboo bats are the lightest of the three woods, making them great for players who need to swing fast. (The first person to really investigate sweet spots did so on tennis rackets.) If there was no loss of energy during the bounce then COR would be 1.0. External forces are the only way to redirect the ball according to the first law of motion. on: function(evt, cb) { This cookie is set by GDPR Cookie Consent plugin. The true CoP should be measured from that point. endobj throughout the paper. /V 7 0 R Regardless of age, the weight of the right handers bat is crucial. When a bat is made out of a hard material, it allows the bat to transfer more energy to the ball when it is hit, enabling the ball to move faster and farther. The bat was swung through an axis 143 mm from the knob end. What is the fluid speed in a fire hose with a 9.00 cm diameter carrying 80.0 l of water per second? The relevant collision equations are derived in the Physics of Baseball and Softball book (and elsewhere) and are: 1. The swing weight of the bat (that is, its moment of inertia) can be determined from the measured period of oscillation when swung as a pendulum. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. 1 inch in length is huge. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. The whole mass of the bat is not involved in the collision, unless the collision happens to occur at the centre of mass of the bat. You can actually hear where the sweet spot is just by tapping a bat yourself. At the major league level, maple bats now account for 75% to 80% of all bats. For most bats all of these "sweetspots" are at different locations on the bat, so one is often forced to define the sweetspot as a region, approximately 5-7 inches from the end of the barrel, where the batted-ball speed is the highest and the sensation in the hands if minimized. This is not an easy rating to obtain. Interesting information on the behaviour of a ball can be obtained by bouncing it on a force plate or on a piezo to measure force vs time. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. The bat barrel initially bends backwards away from the ball while the handle bends outward and the vibration in the handle causes the players top hand to lose contact with the handle. A baseball bat is typically between 30-34 inches in length and can weigh anywhere from 24-30 ounces. Two ounces doesnt seem like much but Ive seen it make a large difference. Graphs of F vs t and x vs t can also be used to generate graphs of F vs x, showing how the force on the ball varies with its compression. Initially, the force on the handle is in the opposite direction to the motion of the handle. } 12 0 obj As Russell explained before, there are two related ideals that we conflate into one sweet spot. However, the COP shifts a long way toward the handle when a batter holds the handle, and plays only a minor role in the feel of the bat for an impact at the sweet spot. There are some models that include oak, but it is not as popular as maple or ash. Jessy is an avid baseball fan and writer for the popular website, Baseball Writes. /Length 996 Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features.

It was found, by measuring the frequencies of lots of aluminum tubes (see photo). The sweet spot of a baseball bat is the area on the bat that produces the most powerful and accurate hit when the ball is struck. If you drop the weight, you will be able to use the bat with greater control and power. The third law explains what happens to a bat when it strikes a ball. Despite the likelihood of your bat breaking, there are things you can do to prevent it. Some of the numbers change with actual speed, but the physics doesnt change. A ball that strikes the bat does not cause it to vibrate at this point. Some hoop mode sounds are recorded in the following QuickTime Movies, using an aluminum bat and several aluminum tubes of various diameters and wall thickness. There is enough physics in it to keep a PhD student busy for a few years. /R [52 74 308 585 ] 232 g bat 871 g bat 1333 g bat. I havent listened to different recordings of hits to see if theres a noticeable difference, says Russell. There is obviously some elastic behaviour in the vertical direction as well, which is why the ball bounces up off the block. So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. Where is the Sweet Spot on a Baseball Bat? A careful analysis of baseball dynamics shows that this special spot is located at the point where an applied force would result in pure rotation of the bat about the handle grip. 29 0 obj 7 0 obj Balls compress along the same F vs x curve, regardless of the ball speed, although the actual compression curve for a given ball will depend on its stiffness. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. If you turn the volume up you will hear how the swing speed affects the sound of the swish through the air. The bounce factor found from these and some additional impacts is shown below.

Metal bats, on the other hand, are lighter and more forgiving, but they lack the power of iron bats. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. At any given time, the center of the circle can be found by fitting a circle to three neighboring points, at say time t, and at times t + 0.02 s and t - 0.02 s. This gives the radius, R, of the circle, from which we can calculate the centripetal force MV2/R as well as the force at right angles to that, given by M (dV/dt). In file A, the tangential COR was surprisingly high, about 0.3. /WhitePoint [0.9505 1 1.089] George has always been passionate about physics and its ability to explain the fundamental workings of the universe. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. 21 0 obj 5P8$ BaPR+"dUkbQ]YH`P. /P 26 0 R 2 5 8 on a bat simply refers to the weight of the bat in ounces. It was found, by measuring the frequencies of lots of aluminum tubes (see photo) that the frequency is directly proportional to the wall thickness and inversely proportional to the tube diameter squared. Is swinging a bat potential or kinetic energy? The bat is 84 cm long, and has a mass of 849 gram. How do you find the acceleration of a system? Baseball is a beloved American pastime, with millions of people playing the game recreationally or professionally each year. Lighter bats, on the other hand, are better suited for contact hitters who are looking to make contact with the ball and generate less power. The ball will rotate about 1/2 a revolution from the initial grip to the release point, in about 0.1 sec or less. 1 0 obj Rather, the physics depends more on the ratio of the bat and ball speeds, regardless of whether the actual speeds are around 1 mph or 100 mph. The idea is to mount a bat as a pendulum and strike it with a ball at various spots along the barrel. However. QuickTime movie files A and B show a baseball bouncing on a block of granite. The physics of baseball Baseball players know from experience that there is a ``sweet spot'' on a baseball bat, about 17cm from the end of the barrel, where the shock of impact with the ball, as felt by the hands, is minimized. A good power hitters bat is an end-loaded one, which allows the player to hit the ball farther. /Matrix [0.4497 0.2446 0.02518 0.3163 0.672 0.1412 0.1845 0.08334 0.9227] According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m .

Join PopSci+ to read sciences greatest stories. How is this described in Mechanics? A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. Where is the center of mass in a baseball bat? There is a greater amount of strength required to swing a wood bat, but the ball exits faster when hit. The answer depends on how fast each bat can be swung. Necessary cookies are absolutely essential for the website to function properly. Popular Science 71.6K subscribers Subscribe 162 19K views 4 years ago Where is the sweet spot on a baseball bat and how do you find it? /P 4 0 R By combining the results of these two separate experiments, we can then work out what happens when a bat is swung at an incoming ball. MLB . << Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. the location where maximum energy is transferred to the ball. On average, players aged 15 to 17 hit 140 feet, while players aged 16 to 18 hit 150 feet, and players aged 18 to 19 hit 165 feet. I simply wanted to know whether a hand launched ball spins at around 100 rpm or whether it could be as high as 1000 rpm. Baseball bats are most commonly made out of wood, such as maple, ash, or bamboo. If you hit . >> Baseball physics is based on fluid dynamics. For the purposes of this paper, I will attempt to examine the . The Physics of Baseball. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. Largest thickness - The sweet spot Bat - Ball Collision Diagrams Vball 1 = Vb Vbat 1 = V2b V bat 2 = V2a Vball = V1a Before After For example, a 33-inch bat with a -3 rating weighs 30 ounces. The ball is spinning clockwise before it bounces and hits the granite block with backspin. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. The ball is spinning clockwise before it bounces and hits the granite block with backspin. No player is perfect so all players will miss hitting in the sweet spot, so every hit could result in baseball bat damage. The length and weight of a bat is tailored to the size, strength and hitting style of the individual player. endobj Learn how the sweet spot correlates with movement and vibration.

After completing his degree, George worked as a postdoctoral researcher at CERN, the world's largest particle physics laboratory. /V 24 0 R 9 0 obj The science of magnetism, while not as well-known as the science of moving energy when a bat hits a ball, is still important in the game. By clicking Accept, you consent to the use of ALL the cookies. /R [316 73 572 791 ] But how does a batter do it? The above results are more or less as expected, in that light bats can be swung faster than heavy bats. /R [52 73 308 791 ] /R [52 73 308 791 ] The film is shown here, taken at 25 frames/sec. Newtons second law, which deals with the value of time, is also important in baseball. The whole mass of the bat is not involved in the collision, unless the collision happens to occur at the centre of mass of the bat. A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand. The sweet spot is found on only one side of the bat. From that you can work out the speed and spin of the ball before and after it bounces. It is almost as easy as walking. /N 21 0 R In principle you could also work out the acceleration due to gravity in Sydney, but not very accurately. These modes are shown in the diagram above.

Do NOT follow this link or you will be banned from the site! Coefficient of Restitution = Relative speed of bat and ball after collision/ relative speed before collision, where "speed of bat" is the speed of the bat at the impact point. Sniper Skin Announces Their Newest Partnership with Bassmaster Opens Pro, Briana Tucker! The effect is known as the "trampoline effect". /N 27 0 R Thats the sweet spot. They can change their flight path after being exposed to different magnetic pulses, and scientists have discovered that big brown bats can adapt to these magnetic shocks. The horizontal speed at the contact point depends on the rate at which the ball spins, as well as on the horizontal speed of the centre of mass of the ball. He received his Ph.D. in physics from the University of California, Berkeley, where he conducted research on particle physics and cosmology. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. The ball is 72 mm in diameter. . It is very surprising that no one seems to have worked this out before. /P 8 0 R The faster the hit ball travels, the longer it should travel. So, for the sake of the integrity of the game and safety, bats have remained wooden. Since its vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesnt cause the bat to vibrate. If you hit a baseball somewhere other than the sweet spot, your hands will feel the vibrations. event : evt, The bounce was filmed at 300 fps and is played back at 30 fps in slow motion. A model is developed for the collision between the baseball and bat, taking into account the transverse bending vibrations of the bat.

Wood bats and aluminum bats have their own set of advantages and disadvantages, and the choice for the player is based on preference. 3. If there is a force of 5,000lb on the ball then . Are you a fan of composite or wood? Scientifically speaking, this is the weakest part of a wooden baseball bat. >> For further details, see American Journal of Physics, September 1998 and also American Journal of Physics, 69, 231-232 (2001). A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. In practice, batters tend to prefer bats that are lighter, rather than more powerful, since lighter bats are easier to swing and make it easier for the batter to connect with the ball. >> It is not the actual weight that determines the swing speed but the swing weight (ie the moment of inertia). /N 15 0 R However, the centripetal force does not act along the axis of the bat, but at an angle, as shown by the orange lines. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. Baseball players obsession with bats is second nature to them. >> According to Science Daily, human hands are sensitive to vibration frequencies between 200-700 hertz and we experience the most pain when those frequencies are between 600-700 hertz. In order to determine how each of the sweet spots influences the "feel" of the bat, measurements were made of the impact forces transmitted to the hands. /N 18 0 R Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! The shoulders reach maximum speed first. The batter needs to exert a small couple to get the swing started, using equal and opposite forces on the handle, otherwise the barrel of the bat will get left behind. } So, using a heavier bat should result in faster hit balls, which means the hit ball will travel farther. However, when the bat strikes the ball at the dead spot then the ball exit speed = V = speed of bat just before the collision. As a result, the fundamental and second vibration modes are both excited with about the same amplitude. The bat breaks when large amplitude vibrations reach the thin part of the handle. 3) Care for your bat Wooden baseball bats are susceptible to cold and moisture. And we divide that by Pi times 9.00 centimeters written as meters so centi is prefix meaning ten times minus two and we square that diameter. endobj I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. >> /Gamma [1.8 1.8 1.8] We can then ask a similar question. When a baseball player hits a ball, it generates enormous amounts of energy. Similar results are obtained at much higher ball speeds, the forces and x values being correspondingly much larger. /R [316 73 572 791 ] << When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second - the impact could mean up to 5,000 lbs of force. The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. >> /P 20 0 R Explains r. cross, "the sweet spot of a baseball bat," american journal of physics, 66, 772-779.
