- 1SpeedSpeed = Distance / Time
- 2Distance TravelledDistance Travelled = Average Speed x Time
- 3AccelerationAcceleration = Change in Velocity /
Time Taken - 4ForceForce = Mass x Acceleration
- 5WeightWeight = Mass x Gravitational Field Strength
- 6EfficiencyEfficiency = Useful Energy / Total Energy
- 7MomentumMomentum = Mass x Velocity
- 8Wave SpeedWave Speed = Frequency x Wavelength
or
Wave Soeed = Distance / Time - 9DensityDensity = Mass / Volume
- 10Work DoneWork Done = Force x Distance
(moved in the direction of the force) - 11Change in Gravitational Potential EnergyChange in Gravitational Potential Energy = Mass x Gravitation Field Strength x
Change in Height - 12Kinetic EnergyKinetic Energy = 1/2 x Mass x Speed squared
- 13PowerPower = Word Done / Time Taken
or
Power = Energy Transferred / Time Taken - 14Energy TransferredEnergy Transferred = Charge Moved x Potential Difference
- 15ChargeCharge = Current x Time
- 16Potential DifferencePotential Difference = Current x Resistance
- 17Electric PowerElectric Power = Current x Potential Difference
or
Electric Power = Current squared x Resistance - 18Force Exerted on a SpringForce Exerted on a Spring = Spring Constant x Extension
- 19Moment of a ForceMoment of a Force = Force x Distance (normal to the direction of the force)
- 20PressurePressure = Force (normal to surface) / surface area
