KS3Physics · Years 7 to 9

Speed and motion

Four lessons that start with questions. Race runners along a track marked in metres, time a trolley with light gates, follow a car’s speedometer through a real journey, watch a distance–time graph grow as a walker moves, and see trains pass from the platform or from each other. Get one wrong and the diagram shows you why. Prefer to read first? Every lesson has animated notes too.

Five quick diagram questions a day from this unit. The ones you get wrong come back sooner. Progress saves in this browser.
