Energy written questions
Structured and data-based Paper 2 practice for work, energy and power: work done, KE/GPE, conservation of energy, power, efficiency, and energy resources.
Learning goals
- Recognise kinetic, potential, nuclear and internal energy stores
- Describe mechanical energy transfer by a force acting over a distance
- Describe electrical energy transfer by an electric current
- Describe energy transfer by heating due to a temperature difference
- Describe energy transfer by electromagnetic and mechanical waves
- Recall and apply Ek = ½mv² in new situations
- Recall and apply Ep = mgh near the Earth's surface in new situations
- State and apply the principle of conservation of energy
- Recall and apply work done = force × distance moved in the force direction
- Recall and apply power = energy transfer / time taken
- Calculate efficiency as useful energy output / total energy input
- Evaluate prescribed electricity-generation resources by efficiency, cost, reliability and environmental impact
