A centripetal force is a net force that causes an object to move in a circular path. According to Newton's first law of motion, a body continues to move in a straight line with uniform velocity, if no external force acts on it. As the velocity of a body moving in a circular path changes continuously, a net force is required to keep the body. Centripetal force can be caused by a normal force, but it can also be caused by other forces. Earth orbits the Sun with the force of gravity acting as the centripetal force keeping the motion relatively circular. Furthermore, not all normal forces are centripetal forces. It is a normal force, but not centripetal The force that causes the centripetal acceleration is named centripetal force and it is directed towards the centre of this circular path. When an object traces along a circular path, its trajectory constantly changes at every instant throughout this circular motion
