Gravitational potential energy
Energy stored due to the height of an object above the base level.
Chemical energy
Energy created due to chemical reactions.
Elastic potential energy
An object that cane go back to its original size after being stretched.
Nuclear energy
The energy stored at the centre of atoms.
Efficiency
The amount of energy that is applied to a device and is useful.

Conduction
Transferring heat through collisions of particles.
Radiation

Radiant heat
Heat transferred by radiation.
Reflected
Bounced off.
Transmitted

Incandescent
A type of light that lights up when it’s hot.
Bioluminescent
A living thing that emits light.
Non-luminous
Objects that don’t emit light.
Scatter
Light that is sent in many directions.
Vibrations
back and forth movements repeated quickly.
Compression
Pushing a material into itself.
