Circular motion

Motion in a circular path

Centripetal force plays a crucial role in circular motion.

It is the Force that makes a body follow a curved path. It acts towards the centre.
Generally denoted by Fc

`Fc= (mv^2)/r`
Since we know that F = ma; therefore `(v^2) /r` is termed as Centripetal acceleration
