EXIT VELOCITY VS. BAT SPEED
Everybody is talking about exit velocity these days but many people don't realize that bat speed is the most important factor in high exit velocity.
Exit velocity depends on many variables, but speed is an objective metric unencumbered by subjective factors. It is raw, objective data. No variables.
Velocity is a vector quantity
Bat speed is a scalar quantity
Speed: how much distance has been covered in a particular time
Velocity: the change of distance in a particular direction with respect to time
Acceleration: the amount of increase or decrease in velocity
Velocity is the speed and direction
The Bat speed Recon™ is measuring the time it takes for the tip of the bat to pass both sensors.
This is both reliable and accurate.
EXIT VELOCITY VARIABLES
The hitter’s bat speed
The point on the ball where it makes contact with the bat
The point on the bat where it makes contact with the ball
The speed of the incoming pitch
The hardness of the ball
The material composition of the bat
The trajectory of the bat approach
If bat speed is consistent from swing to swing, exit velocity will still vary due to the factors listed.
Exit velocity is a subset of bat speed.
•If you hit a ball perfectly, the exit velocity will be higher than bat speed.
•If you hit a ball imperfectly (grounder or pop-up), exit velocity will be lower than bat speed
