        Circular Motion

        In this interactive activity featuring videos adapted from the Rutgers PAER Group, learn about how centripetal force acts on an object to keep it moving in a circular path. In the first video, a man hits a moving ball with a stick so that it travels in a circle. In the next video, a ball is set into motion inside a metal ring on a flat surface; the ball travels a circular path inside the ring until a section of the ring is removed. In the last video, a woman on rollerblades skates in a circle while holding onto a rope anchored by a man at the center of the circle; she also skates in a circle by herself by pushing off with her outside foot.

        This media asset was adapted from Rutger’s Physics Teaching Technology Resource, courtesy of E. Etkina and D. Brookes.
