IB Physics SL A.3.1 Conservation of energy
Practise tracing energy stores and transfers, then using conservation of energy to explain outcomes and calculate speeds or power.
How this is tested
- explain where 'missing' energy goes, such as zero intensity points transferring energy into diffraction maxima
- apply energy conservation to motion by equating mgh and 1/2 mv^2 to show impact speed without air resistance
- describe staged transfers in devices, for example wind kinetic energy to turbine rotation to electrical output
