Centripetal Force

Regardless of the given example , if the centripetal force acting on an object should vanish , the object would no longer moves in its circular path . instead , the object will move on a straight-line path tangent to the circle . To understand well on what will happen when the centripetal force acting on a body vanished , let be the example is a ball whirling using a string . If the string breaks at some instant , the ball will move along the straight-line path at the point where the string broke . In general , a body can move in a circular path under the influence

These moving bodies around the earth circles around the pole every night which gives the idea of time measurement . Part of the dialogue is the creation of the universe by the Supreme Being . From the dialogue of Plato , the Timaeus , it stated that the earth is at the center of the universe and that there are other spherical heavenly bodies rotating around the earth .
