According to Newton’s first law of motion, there can be no acceleration without a net force. So there has to be
a force associated with the uniform circular motion and is directed towards the centre
According to Newton’s first law of motion, there can be no acceleration without a net force. So there must be a force associated with the circular motion and is directed towards the center. It is known as a centripetal force. Apart from this, a body will have tangential acceleration because of velocity and helps in changing its direction at each instant.
