Term
 Speed = Distance Travelled            Time Taken
Definition
 Speed = KPH Distance Travelled = Kilometres Time Taken = Hours
Term
 Momentum = Mass x Velocity
Definition
 Momentum = kg m/s Mass = kg Velocity = m/s
Term
 Change of Momentum = Resultant Force x Time for which it acts
Definition
 Change of Momentum = kg m/s Resultant Force = N Time for which it acts = S
Term
 Changing Units 1 Newton in Kg
Definition
 = 1               10 of a kg
Term
 Changing Units 1kg in Newtons
Definition
 = 10N
Term
 Work Done by a Force = Force x Distance moved by the Force
Definition
 Work Done by a Force = J Force = N Distance moved by the Force = m
Term
 Change in Energy = Work Done
Definition
 Change in Energy = J Work Done = J
Term
 Change in GPE = Weight x Vertical Height Difference
Definition
 Change in GPE = J Weight = N Vertical Height Difference = m
Term
 Kinetic Energy = 1 x Mass x [Velocity]2                                              2
Definition
 Kinetic Energy = J Mass = kg Velocity = [m/s]2
Term
 Resistance = Voltage                    Current
Definition
 Resistance = Ω Voltage = V Current = Amps(A)
Term
 (Vp) = (Np) (Vs)    (Ns)
Definition
 Vp = Voltage across primary coil Vs = Voltage across secondary coil Np = Number of turns on primary coil Ns = Number of turns on secondary coil
Term
 Energy Transfered(work done) = Power x Time
Definition
 Energy Transfered = J Power = Watt (W) Time = s
Term
 Power = Potential Difference x Current
Definition
 Power = Watt(W) Potential Difference = V Current = Amps(A)
Term
 Power = Voltage x Current
Definition
 Power = Watt(W) Voltage = Volts(V) Current = Amps(A)
Term
 Energy Transferred when device is on = Power rating x time
Definition
 Energy Transferred when device is on = J OR KJ Power Rating = W OR KW Time = s or h
Term
 Wave Speed = Frequency x Wavelength
Definition
 Wave Speed = m/s OR mm/s Frequency = Hz Wavelength = m or mm
