Centripetal Force

 

If a body is moving with a constant speed in a circle, as seen from an inertial frame, it is continuously towards the centre of rotation with magnitude vr/r (known as centripetal acceleration), where v is the speed of the particle and r is the radius of the circular path.

 

According to Newton’s second law, this body will experience net force directed towards the centre called the centripetal force.

 

Therefore, net force acting on the body towards the centre = mv2/r , where m is mass of body.

 

Centrifugal force is a pseudo force acting on the body from a rotating frame.
