Closed System: A system that experiences no net change in its total energy when energy transfers occur within it
Conservation of Energy: The law that energy can be transferred, stored or dissipated but never created or destroyed
Efficiency: The ratio of useful output energy transfer to total energy input
Elastic Potential Energy: The store of energy that stretched or compressed objects experience
Elastic Potential Energy is directly proportional to the stiffness constant and to the square of the extension or compression
Fossil Fuels: Coal, oil and gas
Gravitational Potential Energy: The store of energy that all raised matter has
Gravitational Potential Energy is directly proportional to the mass of the object, the distance that it is risen and the gravitational field strength at that point
Joule: The unit used for energy
Joule is equal to the work done when a force of one Newton acts over a distance of one metre
Kinetic Energy: The store of energy that all moving matter has
Kinetic Energy is directly proportional to the object’s mass and to the square of its velocity
Power: The rate at which energy is transferred, or at which work is done
Renewable Energy Resource: An energy resource that can be replenished whilst it is being used
Spring Constant: A measure of a spring’s stiffness
The greater the value, the greater the force required to stretch or compress the spring by a given distance
