Angular momentum (I will refer to its traditional name) also depends upon two things: the angular velocity and the moment of inertia.

Angular momentum is a rotational analog to linear momentum. It is the product of the moment of inertia (the rotational force needed to rotate mass) and angular velocity.

This happens because angular momentum is conserved. Angular momentum is an object's moment of inertia times its angular velocity. If one of the latter two increases, the other decreases, and vice ...

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

Stretching the limbs out will increase the moment of inertia, therefore decreasing the angular velocity — which is essential for a neat and flawless dive into the water.
