Simulation of piston sliding back and forth inside an engine cylinder This simulation shows a piston sliding back and forth inside an engine cylinder, demonstrating how lubrication reduces friction. A blue arrow on the left shows the driving force pushing the piston; red arrows on the piston show friction resisting its motion each stroke. Three […]

Simulation of Friction, lubrication using a crate This interactive GCSE Physics simulation shows how lubrication reduces friction between surfaces. As you increase lubrication, the friction force drops, so less energy is transferred to the thermal store (less heating/heat trail) and more of the work done by the push goes into the object’s kinetic energy (it

This simulation teaches power as the rate of energy transfer / work done. This approach matches the AQA GCSE Physics specification’s recommended emphasis that students understand power as how quickly energy is transferred (or how quickly work is done) and can apply (P = E/t) and (P = W/t) (and, for circuits, (P = IV).

Earth’s gravitational field Simulation This is a full-screen interactive HTML5 simulation of Earth’s gravitational field, designed for GCSE Physics. It visualises the concept that the force of gravity near Earth is caused by the gravitational field surrounding it. What students see on screen: The canvas shows a deep-space background with Earth sitting at the base,

Simulation of thermal conductivity This simulation helps GCSE Physics students visualise thermal conduction — the transfer of energy through a material from a region of higher temperature to a region of lower temperature. Students select from four materials (Wood, Glass, Steel, and Copper) and observe in real time how heat spreads across the rod from
