Description
This unit explores forces, deformation, Hooke’s Law, moments, and work done. It covers pressure in liquids, atmospheric pressure, upthrust, and equilibrium, as well as simple machines and force-extension relationships, highlighting how forces affect motion, friction, and object deformation.
This unit builds on pupils’ prior learning from Forces, where they explored the basics of contact and non-contact forces and how they affect motion. It deepens their understanding by examining hidden forces, such as turning forces, forces that hold objects on surfaces, and buoyancy, highlighting how these forces interact in everyday situations. This prepares pupils for the next unit, Particle explanations of density and pressure, where they will apply their knowledge to understand how particle behaviour influences density, pressure, and the forces exerted by fluids.
