Question

Define centripetal acceleration?

Answer 1

Step 1: Definition

The concept of centripetal acceleration states that any object travelling in a circle, also known as circular motion, will have an acceleration pointing towards the circle's center. Because it has a direction, it is a vector.

Step 2: Example

For an electron revolving round the nucleus in a circular path, the electrostatic force of attraction between the electron and the nucleus provides the necessary centripetal force.
