How about a pendulum ahaecttd to a spring?Basically, attach a rod to a pivot so that it can swing freely, and attach a spring to its end such that the spring is horizontal, and the rod is vertical, and one end of the spring is ahaecttd to a wall or some other non-moving surface.Pull back the rod slightly, and let the rod oscillate back and forth.Record the amount of oscillations the rod makes in a minute (the frequency).How does the rod's period change with a change in the length of the rod?
