Edexcel IGCSE Physics Energy resources and energy transfers questions
Energy resources and energy transfers covers energy stores, transfer pathways, efficiency, thermal physics, work, power and methods of generating electricity.
Energy resources and energy transfers topic overview
Energy resources and energy transfers covers energy stores, transfer pathways, efficiency, thermal physics, work, power and methods of generating electricity.
State the initial and final stores, name the transfer pathway, account for wasted energy, and show every substitution when comparing efficiency, work or power.
Question types in energy resources and energy transfers
- Energy-store and transfer descriptions, often using Sankey diagrams.
- Efficiency, work, kinetic energy, gravitational potential energy and power calculations.
- Conduction, convection, radiation and insulation explanations.
- Evaluation of renewable and non-renewable electricity generation methods.
Energy resources and energy transfers subtopics
Choose a subtopic for its syllabus points, answering guidance and worked exam questions.
4.a Units
4.1 use the following units: kilogram (kg), joule (J), metre (m), metre/second (m/s), metre/second² (m/s²), newton (N), second (s) and watt (W)
4.b Energy transfers
4.2 describe energy transfers involving energy stores: energy stores: chemical, kinetic, gravitational, elastic, thermal, magnetic, electrostatic, nuclear energy transfers: mechanically, electrically, by heating, by radiation (light and sound)
4.c Work and power
4.11 know and use the relationship between work done, force and distance moved in the direction of the force: work done = force × distance moved W = F × d
4.d Energy resources and electricity generation
4.18P describe the energy transfers involved in generating electricity using: wind water geothermal resources solar heating systems solar cells fossil fuels nuclear power
