In physics, the angular velocity is defined as the rate of change of angular displacement and is a vector quantity (more precisely, a pseudovector) which
Torque, moment, or moment of force is the tendency of a force to rotate an object about an axis, fulcrum, or pivot.

Perfectly inelastic collision
A collision is an isolated event in which two or more moving bodies (colliding bodies) exert forces on each other for a relatively short time. Collision is
