... In this section we show that the projection of uniform circular motion on a diameter of the circle follows simple harmonic motion. A simple experiment (Fig. 14.9) helps us visualize this connection. Tie a ball to the end of a string and make it move in a horizontal plane about a fixed point with a c ...
