Angular momentum under central force for a rotating body

Correct answer: D. Constant

  • A. Zero
  • B. Minimum
  • C. Maximum
  • D. Constant

Explanation

Angular momentum is conserved under central forces. In the case of a rotating body under a central force, the angular momentum remains constant unless an external torque is applied. This is a result of the conservation of angular momentum in the absence of external torques.

About Angular and Linear Quantities

Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
