Labels:text | cartoon | circle OCR: CENTRIPETAL FORCE FAIRGROUND RIDE DIRECTION OF ROTATION CENTRIPETAL FORCE As a wheel rotates, all its parts move in different directions. Inertia, however, tends to make things move in straight lines, so the wheel relies on centripetal forces to hold itself together. Anything that is loosely attached will fly off. The people on a fairground ride, for example, are held on by the centripetal force of the ropes. If one of the ropes were to break, the passenger would fly off at a tangent.
