Angular Momentum

Angular Momentum is equal to the product of mass, velocity, and distance from mass to axis rotation. Another equation for angular momentum is the moment of inertia multiplied by the angular velocity. Angular momentum is not gained or lost from the time the gymnasts pushes off the mat. However, gymnasts are able to change their rate of rotation. They do this by changing their center mass of pulling in their arms or vice versa to perform tricks without pushing off of anything.
