CAIE IGCSE Physics 1.7.2.1 Mechanical or electrical work done is
Practise recognising work as energy transferred, from lifted masses, stationary loads and friction slowing a trolley on a rough surface.
How this is tested
- link mechanical work done to the gain or loss of energy in a lifted mass or moving trolley
- distinguish no work done from energy transfer when a load is hanging without moving
- explain how work against friction reduces kinetic energy and produces thermal energy
