Circular Motion
A particle moves in a circular path of radius and velocity . It then increases its velocity to while travelling along the same circular path. The centripetal acceleration of the particle has changed by a factor of?

The centripetal acceleration is directly proportional to the square of the velocity. Doubling the speed increases the acceleration by a factor of 2 2 = 4 .
