The radial acceleration is also considered as:
Correct answer: B. Centripetal acceleration
- A. Angular acceleration
- B. Centripetal acceleration
- C. Tangential acceleration
- D. Translator acceleration
Explanation
Radial acceleration, also known as centripetal acceleration, is the acceleration of an object moving in a circular path towards the center of the circle. It is directed towards the center of the circle and is necessary to keep the object on its circular 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.
