Forces, electricity and motion
Three physics lessons in rising difficulty: forces, then circuits, then motion graphs and equations.
These three physics lessons rise in difficulty. Forces and Newton's laws explain why things start, stop and change direction. Electric circuits apply the same habits of measuring and modelling to current, voltage and resistance. Motion, for ages 14 to 15, describes movement precisely with graphs and equations.
