Units of Measurement
Joules = Energy (Work Done)
Hz = Hertz (Frequency)
W = Watts (Power)
V = Volts (Current/Amps)
N = Newtons (Force)
Equations
Power= work done/time taken
efficiency = useful energy output/total energy supplied
work done = force x distance moved
kinetic energy = 1/2 x mass x (speed)^2
