TYPES

can be produced by chemicals reacting, respiration in cells, movement of two objects against each other ie friction

Stored energy eg a boy sitting at the top of a slippery dip has energy stored as a result of his position

when you pick up a pen and hold it up, you give it gravitational potential energy

also springs

chemical energy is stored until it is converted eg in food it is converted to heat when it is eaten; in a match head it is converted to light and heat when it is moved against the box; to electrical energy when a battery is connected to a circuit

The energy of something moving eg a car rolling down a hill has kinetic energy

THE ABILITY TO MAKE THINGS MOVE

energy types are transformed from one type to another eg when a falling rock hits the ground, kinetic energy is transformed into sound energy.The blue lines show some common energy transformations

ENERGY CANNOT BE CREATED OR DESTROYED ONLY TRANSFORMED
