The angular momentum of a rotating body is conserved when
A) no net torque acts on the body.
B) no net force acts on the body.
C) when the body has a constant angular acceleration.
D) the shape of the body does not change.

Question

Quizplus · Accepted Answer

According to the principle of conservation of angular momentum, the angular momentum of a rotating body remains constant as long as there is no net torque acting on the body. Therefore, option A is the correct choice. Option B is incorrect because the conservation of angular momentum is not related to net force acting on the body. Option C is incorrect because the angular momentum can change even when the body has a constant angular acceleration. Option D is also incorrect because the conservation of angular momentum is not related to the shape of the body.
