The acceleration for an object moving in a circle points towards the center of the circle and has a magnitude of:

La te xi t 1

Where r is the radius of the circle and v is the speed of the motorcycle. Of course, you can probably guess that we have a special name for this fake force—we call it the centrifugal force which literally means “center fleeing force”. Don’t confuse this with centripetal force which is the force that causes an object to move in a circle.
