REVIEW & SUMMARY
Torque as a Vector In three dimensions. torque T’ is a vector quantity defined relative to a fixed point.
Angular Momentum of a Particle The angular momentum f of a particle with linear momentum p. mass m, and linear velocity is a vector quantity defined relative to a fixed point (usually an origin).
Newton’s Second Law ill Angular Form Newton’s second law for a particle can be written in angular.
Angular Momentum of a System of Particles The angular momentum L of a system of particles is the vector sum of the angular momenta of the individual particles.
Angular Momentum of a Rigid Body For a rigid body rotating about a fixed axis. the component of its angular momentum parallel to the rotation.
Collaborationist of Angular Momentum The angular momentum or a system remains constant if the net external torque acting on the system is zero:
