Have you ever been to an amusement park and wondered how a rollercoaster goes around the loop of the track?
Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while moving through the loop. This change in direction is caused by the presence of unbalanced forces and results in an acceleration. The acceleration of the coaster could be slower downwards and then speed up when going upwards; these changes in acceleration
