When an object experience circular motion, the direction of centripetal acceleration is
Correct answer: A. Towards center
- A. Towards center
- B. Along tangent
- C. Along the directicn of motion
- D. Opposite of the direetlon of motion
Explanation
The direction of the instantaneous velocity is shown at two points along the path. Acceleration is in the direction of the change in velocity, which points directly toward the centre of rotation-the centre of the 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.
