Question

when angular momentum of body is conserved​

Answer 1

Answer:

Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.

Answer 2

Angular momentum is conserved when the net torque on the body is zero

dL/dt = Torque

dL/dt = 0

Hence, L has no change or L is constant
