Rate/Speed of rotation about an axis
The speed of rotation is important and must be controlled and adjusted depending on the height of the bounce. To much height and push off the feet will cause over rotation and vice-versa.
Inertia can be utilised to control the speed of rotation. For example tucking during a somersault will speed the rotation up while straightening out to land the skill will slow the speed of rotation. Click on inertia for more information.
