Energy Work Power
Key knowledge — Energy Work Power
Formulas & equations
Work done = force × distance in direction of force (W = Fd, unit: J)Kinetic energy = ½mv²Gravitational PE = mghPower = work done ÷ time = energy transferred ÷ time (P = W/t, unit: W)Efficiency = useful energy output ÷ total energy input (× 100 for %)Electrical energy = power × time (E = Pt)
Key facts & rules
- Conservation of energy: energy cannot be created or destroyed, only transferred or converted.
- All energy eventually becomes thermal energy (heat).
- 1 kWh (kilowatt-hour) = 3.6 × 10⁶ J.
- Renewable energy: solar, wind, hydroelectric, tidal, geothermal, wave, biomass.
- Non-renewable: fossil fuels (coal, oil, gas), nuclear (uranium).
- The Sankey diagram shows energy transfers — width of arrow ∝ amount of energy.

About Energy, Work & Power on IGCSE 0653
Energy cannot be created or destroyed, only transferred. Work is done when a force moves through a distance. Power is the rate of energy transfer. Students must calculate kinetic energy, gravitational potential energy and efficiency.
What's covered:
- Kinetic energy: ½mv²
- Gravitational potential energy: mgh
- Work done: force × distance
- Power = work ÷ time (watts)
- Conservation of energy
- Efficiency = useful output ÷ total input
- Renewable and non-renewable energy sources
