- 1Distance travelledDistance travelled = speed x time
- 2AccelerationAcceleration = change in velocity / time taken
- 3ForceForce = mass x acceleration
- 4WeightWeight = mass x gravitational field strength (N)
- 5EfficiencyEfficiency = useful energy transferred by the device/total energy supplied to the device
- 6MomentumMomentum= mass x velocity
- 7Wave speedWave speed = wavelength(λ)
x frequency - 8Wave speedwave speed = Distance(x)/time
- 9DensityDensity = mass/volume
- 10Work doneWork done = Force x distance moved in the direction of the force
- 11Change in gravitational potential energyΔGPE = mass x gravitational field strength x Δheight
- 12Kinetic energyKE= 1/2 x mass x (speed)²
- 13PowerPower = work done / time taken
- 14Energy transferredEnergy transferred = charge moved x potential difference
- 15ChargeCharge = current x time
- 16Potential differencePotential difference = current x resistance
- 17PowerPower = energy transferred / time taken
- 18Electrical powerElectrical power = current x potential difference
- 19Electrical powerElectrical power = current² x resistance
- 20Force exerted on a springForce exerted on a spring = spring constant x extension
- 21Momentum of a forceMomentum of a force = force x distance normal to the direction of the force
- 22PressurePressure = force normal to surface / area of the surface
