The net acceleration of a particle in circular motion is:
Correct answer: A. Towards the centre
- A. Towards the centre
- B. Always along the radius
- C. Irregular
- D. Circular in motion
Explanation
The net acceleration in uniform circular motion is the centripetal acceleration directed radially inward (toward the centre). This inward acceleration is required to continuously change the direction of the velocity vector.

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.
