Detailed practical instructions and other notes that explain how to get students to measure their power by running upstairs.

Fun, interactive research-based simulations of physical phenomena that you can download or run from the site – this one covers kinetic and potential energy, and energy conservation.

A comprehensive site about generating electricity and the issues behind it.

This interactive roller coaster ride produced for Teachers' Domain illustrates the relationship between potential and kinetic energy. As the coaster cars go up and down the hills and around the loop of the track, a pie chart shows how energy is transformed back and forth between gravitational potential energy and kinetic energy.

Resources for teaching a lesson about the use of different balls in different sports, including a video.

One of a set of animations that you can download and play. This one is uses the example of an electric motor lifting a weight You can measure the work done by the motor and its input and output powers. It starts at a very basic level and moves up in stages. Although the experiment seems simple it can be quite tricky to do for real. So this simulation helps get the ideas across and hopefully enthuses students to try it in the real world.

Here learners construct a small-scale version of a classic carnival game. A large marble is rolled along a track made from a commonly available and inexpensive metal shelf bracket. The track is gently bent so that there is a flat portion, then a small hill, and finally a steep uphill portion. The objective is to roll the ball so that it goes over the first hill, but does not come back over the hill -- the ball should remain in the dip between the two hills. The process involves nice illustrations of the interplay of kinetic energy, potential energy and friction

Students use the interactive to investigate work, energy and power

A site that revises weight, mass, work and power.

An activity that revises energy, work, kinetic and potential energy.

A site that revises work, k.e. and p.e. and how it applies to theme park rides.
