what does work mean in terms of physics?
it means a force acting over a certain distance (Vector). the equation to work it out : work done (joules)= force (newtons) × distance (metre) note: nm (newton metre) = joules (j)

what is kE gain?
The kinetic energy an object has depends on its: Mass and Speed. equation: KE = ½ mv2
5 of 11
what does term GPE stand for and mean?
Gravitational Potential Energy .above the Earth’s surface we have potential (stored) energy. The amount of gravitational potential energy an object on Earth has depends on its: mass height above the ground
6 of 11
what is equation for potential energy?
mass × gravity × height

what are the three main units in electricity?
A=amps- flow rate of electrons. V=volts.energy possessed by circuit (the push/ potential energy) Ω=ohms-(amount of resistance to electrons)
8 of 11
what two factors must be present for current to flow?
1.a power supply (voltage/ potential difference) 2.a complete circuit
9 of 11
what is equation for current?
charge flowing (electrons)/ time (seconds) note: charge= coulombs . 1 coulomb=6.24 x 10( to power of 18) note: I(amps)=Q(coulombs)/ T(time)
