Angular Momentum

Rotation about an axis

Angular momentum is created by torques whilst in contact with the bed during the take off phase.  The energy remains in the body until it is removed by other torques upon landing in the bed.  You must be in contact with the bed to create a torque therefore no extra angular momentum can be created during the flight phase of a skill.

Angular momentum is the amount of rotational energy in the body as it rotates about an axis.
