Jun 3, 2015 · Real experiments with ball-bat collisions have been done that actually prove the point. There are many things that determine the launch angle of a batted ball, including the downward angle of the ball, the upward angle of the bat, the squareness of the collision, and the spin of the ball.
Jun 29, 2017 · Specifically, the spin creates air turbulence behind the ball resulting in Magnus Force which pushes the ball upwards and counteracts gravity. This produces the basic relationship: the higher the spin rate on a four-seam fastball the less it will drop in height as it travels from the pitcher’s hand to the plate.
Feb 3, 2011 · The COR deals with how elastic the collision is between two objects — in our case, the bat and ball. A higher COR means the ball bounces off the bat harder. (In the case of a baseball colliding with a bat, the COR is about 0.55, meaning the ball bounces off with just over half of its original velocity.)
Oct 29, 2024 · According to Statcast, hitters facing fastballs with spin rates above 2,500 RPM had a batting average of just .192 and a slugging percentage of .368 in 2023, compared to .259 and .436 for fastballs with below-average spin rates. On breaking balls, the difference is equally stark. Sliders and curveballs with higher spin rates generate more break ...

Let’s begin with a brief explanation of the basic physics of hitting a baseball, specifically what causes a baseball to come off the bat with a high exit velocity. These are the aspects that directly create exit velocityin a batted ball: 1. bat speed 2. mass of the bat 3. pitch speed 4. collision efficiency (hitting the ball on the sweet spot) All ...
Now, let’s get into the statistical relationships among bat speed, exit velocity, and productive hitting. We have established that bat speed is an important aspect of a high exit-velocity hit from a physics standpoint, but running some correlations on our in-gym hitters can give us a better idea on just how important. By revisiting the data used in...
Now that we have more clarity on the relationships among bat speed, exit velocity, and offensive production, let’s examine the implications of these findings on training productive hitters. In the data from our in-gym hitters mentioned above, there is a clear relationship between bat speed and exit velocity, and since exit velocity is one of the ma...
We know bat speed is an important tool in becoming an effective hitter and producing a batted ball with high exit velocity. Coaches must train hitters accordingly with the intent to swing the bat fast and make flush contact, train with some variability and use technology when available to pair the outcomes of bat speed and exit velocity to the hitt...

Our primary results are as follows: (1) For a given angle of incidence, the scattered spin is nearly independent of the incident spin; (2) The spin of the scattered baseball is considerably larger than expected for a model whereby the ball rolls before leaving the surface. Implications for the spin of batted baseballs are explored.

May 26, 2022 · It also doesn’t help that the process of categorizing batted ball spin is imperfect. The basic rundown: In Trackman data, a spin axis of 180 degrees represents perfect backspin; therefore, an axis of zero or 360 degrees — which are functionally the same — represent perfect topspin. Everything in between the poles result in a mixture of ...
