The applet design by prof Hwang, modified layout by Ahmed
Original applet at [url=http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=2119.0]relation between Circular motion and Simple Harmonic Motion (SHM)[/url]

The object moves along the circle at constant speed, but even though its overall speed is constant, the x and y components of its velocity are continuously changing, as shown by the unequal spacing of the points when projected onto the line below.
Projected onto the line, its motion is the same as that of an object experiencing a force F=-kx.

You can adjust fps (frames per second) to slow down the motion in the simulation.
