Answer:

Acceleration is directed toward the center.

Step-by-step explanation:

Centripetal force is a force that makes a body follows a curved path. This force act on the object to continue moving on a circular path.

Any object travelling along a circular path of radius and velocity has an acceleration directed towards the center. The direction of centripetal acceleration is toward the center of curvature . Mathematically centripetal acceleration can be represented as

a = v²/r

where v = velocity

r = radius

The formula of centripetal acceleration represent the acceleration of an object in a circle of radius r and at a speed of v.
