transformations

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

Kinetic

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

Potential

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

chemical

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

Elastic

also springs

Gravitational

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

magnetism

light

sound

Heat

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

Electrical
