Question

State principal of conservation of angular momentum and prove it

Answer 1

LAW OF CONSERVATION OF ANGULAR MOMENTUM. zero , the total angular momentum of the system about that axis remains constant." According to the second law of motion net force acting on a body is equal to its rate of change of linear momentum.

Answer 2

Answer:

The linear momentum and angular momentum of the body is given by →p=m→v and →l=→r×→p about an axis through the origin. The angular momentum →l may change with time due to a torque on the particle. ∴→l = constant, i.e. →l is conserved. ... its angular velocity will also change if there is no external torque
