How do you calculate distance travelled?
Distance travelled = Average speed x Time
1 of 22
How do you calculate acceleration?
Acceleration = (Final velocity - initial velocity) / Time
2 of 22
How do you calculate force?
Force = Mass x Acceleration
3 of 22
How do you calculate weight?
Weight = Mass x Gravitational field strength (10N/Kg)
4 of 22
How do you calculate energy efficiency?
Engery efficiency = (Useful energy transferred by the device) / (Total energy supplied to the device)
5 of 22
How do you calculate Momentum?
Momentum = Mass x Velocity
6 of 22
How do you calculate wave speed? (Including wavelength)
Wave speed = frequency x wavelength
7 of 22
How do you calculate wave speed? (Including distance)
Wave speed = distance / time
8 of 22
How do you calculate density?
Density = Mass / Volume
9 of 22
How do you calculate work done?
Work done = force x distance moved in direction of force
10 of 22
How do you calculate change in gravitational potential energy?
Change in GPE = Mass x gravitational field strength x change in vertical height.

How do you calculate Kinetic energy?
Kinetic energy = 1/2 x mass x (Velocity squared)
12 of 22
How do you calculate power? (Including work done)
Power = work done / time

How do you calculate energy transferred?
Energy transferred = charge moved x potential difference.
14 of 22
How do you calculate charge?
Charge = current x time
15 of 22
How do you calculate Potential difference?
Potential difference = current x resistance
16 of 22
How do you calculate Power? (Including energy transferred)
Power = Energy transferred / Time
