Simple harmonic motion is oscillatory motion. It differs from other types of motion in that it is periodic and it has a restoring force; this means that in simple harmonic motion, there is a force that “pushes” back again the motion of the object, trying to restore object to its original state. Consider the list of everyday motions below. Choose one motion that is an example of simple harmonic motion and explain why you think it represents simple harmonic motion. Be sure to identify both the motion and the restoring force. Then, choose a second example that represents periodic motion, but not simple harmonic motion, and describe why it is not an example of simple harmonic motion.
Everyday examples:
Foucault Pendulum, the hands of a clock, car shock absorbers, a plucked guitar string,the blades of a fan, bungee jumping, a diving board, the wheel of a car, a ball twirled on a string, the Earth revolving around the Sun
