Question

Define centripetal acceleration .
[long answer].... ​

Answer 1

Explanation:

If an object moves in a circle it changes its velocity i.e. it is accelerating. This acceleration is known as the centripetal acceleration.

Answer 2

Answer:

At every point in a circular motion the body feels an outward force which is tangential to circular path.This force is known as centripetal force.The acceleration ibsevred due to this force is centripetal acceleration.

Explanation:

Suppose you take a stone tied to a string and whirl it.on releasing the stone it moves in tangent to the circular path and the acceleration is due to the centripetal acceleration.
