chemical energy: energy that is stored in the chemical bonds of substances, such as foods, fuels and batteries
combustion engine: an engine that converts heat from the burning of a fuel into motion; found in most cars, motorbikes and aeroplanes
efficiency: a measure of how much of the total energy supplied to a device is used, rather than wasted; efficiency = (useful energy) / (total energy input)
-
electric motor: an engine that converts chemical energy from a battery into electrical energy to produce motion (kinetic energy); found in electric cars
-
energy: the capacity to do work; energy comes in different forms (light, heat, electricity) and can be transferred from one object to another or transformed from one type to another, but never created nor destroyed
energy transfer: the movement of energy from one object to another, possibly undergoing a transformation at the same time
-
gravitational field: the space around an object in which another object experiences a gravitational force
gravitational potential energy: the energy stored in an object because of its position in a gravitational field
-
internal combustion engine: an engine that converts heat from the burning of a fuel into motion; found in most cars, motorbikes and aeroplanes
-
-
law of conservation of energy: the basic principle that energy can never be created nor destroyed, just transferred between objects and transformed between different types

-
power station: a building containing machines for generating electricity from a primary energy resource (e.g. coal, nuclear, hydro)
radioactivity: the release of energy as radiation from certain substances, such as uranium
Sankey diagram: a diagram that shows how energy is transferred and/or transformed by a process or device; each type of energy involved is represented as an arrow; the thickness of each arrow indicates the amount of energy of that type; the combined thickness of the "input" arrows must equal the combined thickness of the "output" arrows because of the law of conservation of energy

-
turbine: a device that spins when air, water or steam pushes against it
waste energy: the energy supplied to a device that is not put to use, usually escaping to the surroundings as heat and sound
