Key Stage 2
A car is something with 4 wheels and an engine that people can drive from one place to another.
Key Stage 3
A car is a 4 wheeled vehicle used to transport people between two locations.
- Cars get their energy from the combustion of a fuel or from a battery. Both of which are stores of chemical potential energy.
- When a car accelerates energy is transferred usefully from the chemical potential energy store of the fuel/battery to the kinetic energy store of the car. However, energy is wasted when it is transferred from the chemical potential energy store of the fuel to the thermal energy store of the engine.
- When a car decelerates energy is transferred from the kinetic energy store of the car to the thermal energy store of the brakes.
