Question

define centrepetal force

Answer 1

A force which acts on a body moving in a circular path and is directed(pointed) towards the centre around which the body is moving.

Answer 2

Answer:

centripetal acceleration, the acceleration of a body traversing a circular path. Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration.
