Correct answer: B. Centripetal acceleration
- A. Centrifugal acceleration
- B. Centripetal acceleration
- C. Tangential acceleration
- D. angular acceleration
Explanation
The acceleration directed toward the center of a circular path, required to keep an object moving in that path.

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.
