Pendulum & Newton's cradle

A pendulum is a weight hung from a fixed point so that it can swing freely. This is often seen in very old clocks.
When the pendulum is pulled away from its resting position and then released, it begins to swing back and forth due to gravity. This movement is an example of oscillating motion.

In this experiment you can check the effect of damping (or gravity) on a pendulum's motion.  You can also experience Newton's cradle, see how energy is transferred between the pendulums, and check out the difference between elastic and inelastic collisions.

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!
