Centripetal force, illustration. A hand spins a ball in a circle on the end of a string, demonstrating centripetal force. Centripetal force is a force that makes a body follow a curved path. Newton's First Law states that an object will continue in a state of rest or uniform motion in a straight line unless acted upon by a force. In this demonstration the hand exerts a force on the string which pulls the ball towards the centre. This centripetal force prevents the ball from continuing in a straight line.
