Pitching injuries are rampant. Arm pain is all too common. But, what should you do if the baseball player in your life has pain? Learn the do's and don'ts in this video.

Unit vectors and the derivative are used to determine the velocity and acceleration of an object from the object’s r position vector. The motion is identified as Uniformly Accelerated Motion.

Vector components are reviewed. Unit vectors are introduced and an example is walked through. The “r” position vector is introduced and an example using both “r” position vector and unit vectors is worked through.

In this video I explain six major factors and all the sub-factors that go into why some pitchers throw with higher velocity than others. If you leave pitching velocity on the table, you'll end up regretting it later. Though there are a...
