An oscillating object is an object that moves back and forth, and returns to its initial position after a certain amount of time. Familiar examples include a ball rolling in a bowl or a pendulum swinging back and forth.

In this experiment you can experience the effect of gravity and friction on oscillating motion, you can observe the difference between elastic and inelastic collisions,  and you can see how changing the material of the objects affects its motion.

At anytime during the experiment you can test your knowledge by answering a series of questions. They are also a good tool to help you to understand the ideas behind the experiment better. If you have questions, be sure to check out the information page!
