Centripetal Acceleration in Circular Motion

What is the formula for calculating centripetal acceleration in circular motion?

a) v² / r

b) r / v²

c) r * v

d) 2 * r * v

Answer:

The correct formula for calculating centripetal acceleration in circular motion is a) v² / r.

Centripetal acceleration is the acceleration directed toward the center of a circular path. It is calculated using the formula a = v² / r, where 'a' is the centripetal acceleration, 'v' is the velocity, and 'r' is the radius of the circular path.

By understanding this formula, we can determine the centripetal acceleration of an object moving in a circular motion by knowing its velocity and the radius of the path.
