Biofuel
any fuel taken from living or recently living materials, such as animal waste
Carbon neutral
a biofuel from a living organism that takes in as much carbon dioxide from the atmosphere
Geothermal energy
energy released by radioactive substances deep within the Earth
National grid
the network of cables and transformers used to transfer electricity from power stations to consumers (i.e., homes)
nuclear fuel
substance used in nuclear reactors that releases energy due to nuclear fission
nucleus
tiny positively charged object composed of protons and neutrons at the centre of every atom
reactor core
the thick steel vessel used to contain fuel rods, control rods and the moderator in a nuclear fission reactor
renewable energy
energy from natural sources that is always being replenished so it never runs out
Vector
a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
Scalar
having only magnitude, not direction.
Displacement
the action of moving something from its place or position.
Velocity
the speed of something in a given direction.
