Energy
What this topic asks you to be able to do
- State that energy can be held in kinetic, gravitational potential, chemical, elastic (strain) and nuclear stores, and also in electrostatic and internal (thermal) stores
- Describe how energy passes from store to store across events and processes, including cases of transfer through forces (mechanical work done), electrical currents (electrical work done), heating, and through electromagnetic, sound and other waves
- Know the principle of conservation of energy, and apply it whenever energy passes from one store to another in an event or process
- Recall the kinetic energy equation Ek = 1/2 mv² and use it in calculations
- Recall ΔEp = mgΔh, which gives the change in gravitational potential energy, and use it in calculations
