Power (P)
Energy Transferred (E)
Time (t)
Power = Energy Transferred / Time P = E / t Watts = Joules / Seconds
Potential Difference (V)
Current (I)
Resistance (R)
Potential Difference = Current x Resistance
V = I x R
Volts = Amps x Ohms
Energy (E)
Charge (Q)
Potential Difference (V)
Energy = Charge x Potential Difference E = Q x V Joules = Coulombs x Volts
Power (P)
Current (I)
Resistance (R)
Power = Current² x Resistance P = I² X r Watts = Amps² x Ohms
Force (F)
Spring Constant (k)
Extension (e)
Force = Spring Constant x Extension F = k x e Newtons = Newtons/Metre x Metres
Force (F)
Spring Constant (k)
Extension (e)
F = k x e Force = Spring Constant x Extension Newtons = Kilograms/Seconds² x Metres
Force (F)
Mass (m)
Acceleration (a)
Force = Mass x Acceleration F = m x a Newtons = Kilograms x metres/second²
Work Done (W)
Force (F)
Distance (s)
Work Done = Force x Distance
W = F x s
Joules = Newtons x Metres
Power (P)
Potential Difference (V)
Current (I)
Power = Potential Difference x Current P = V x I Watts = Volts x Amps
Kinetic Energy (Ek)
Mass (m)
Velocity (v)
Kinetic Energy = 1/2 x Mass x Velocity²
Ek = 1/2 x m x v²
Joules = 1/2 x Kilograms x Metres/Second²
Accelaration (a)
Velocity (v)
Time (t)
Acceleration = Final Velocity - Initial Velocity / Time a = v - u / t Metres/Second² = Change in Metres/Second / Seconds
Momentum (p)
Mass (m)
Velocity (v)
Momentum = Mass x Velocity
p = m x v
Kilogram Metres/Second = Kilograms x Metres/Second
Pressure (p)
Force (F)
Area (A)
Pressure = Force / Area p = F / A Pascal = Joules / Metres²
Velocity (v)
Frequency (f)
Wavelength (λ)
Velocity = Frequency x Wavelength v = f x λ Metres/Second = Hertz x Metres
Charge (Q)
Current (I)
Time (t)
Charge = Current x Time Q = I x t Coulombs = Amps x Seconds
