In rotational motion, angular momentum plays a role which is analogous to that played by _ in linear motion.
Correct answer: B. Linear momentum
- A. Linear velocity
- B. Linear momentum
- C. Linear acceleration
- D. Inertia
Explanation
Angular momentum is completely analogous to linear momentum. It has the same implications in terms of carrying rotation forward, and it is conserved when the net external torque is zero. Angular momentum, like linear momentum, is also a property of the atoms and subatomic particles.

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.
