|
conduction
|
The transfer of heat through a material by transferring kinetic energy from one particle to another.
|
|
|
conductor
|
A material which allows charge to move easily through it.
|
|
|
conservation of energy
|
The principle that the total energy of a system stays the same, that energy cannot be created or destroyed (only stored or transferred).
|
|
|
elastic potential energy
|
Energy stored in squashed, stretched or twisted materials.
|
|
|
energy transfers
|
Changes from one form of energy to another form of energy.
|
|
|
gravitational field strength
|
Force per unit mass. Measured in newtons per kg.
|
|
|
gravitational potential energy
|
The energy stored by an object lifted up against the force of gravity. Also know as GPE.
|
|
|
infrared radiation
|
Electromagnetic radiation emitted from a hot object.
|
|
|
insulator
|
Material that does not allow charge or heat to pass through it easily.
|
|
|
internal energy
|
Energy stored in all materials, including energy due to the motion of particles and the chemical bonds between them.
|
|
|
kinetic energy
|
The energy that moving objects have.
|
|
|
mass
|
The amount of matter an object contains. Mass is measured in 'kg'.
|
|
|
seismic waves
|
Shock waves travelling through the Earth, usually caused by an earthquake.
|
|
|
temperature
|
How warm or cold something is.
|
|
|
thermal equilibrium
|
A situation where two objects are at the same temperature and there is no overall transfer of energy between them.
