PPT-Angular Momentum

Movement around a fixed point or axis Spin somersault Occurs when a force is applied outside the centre of mass An off centre force is referred to as an eccentric force Examples of a force being applied outside the centre of mass of an object or body to cause rotation . What was Angular Momentum Again?. If a particle is confined to going around a sphere:. At any instant the particle is on a particular circle. r. v. The particle is some distance from the origin, . r.
