  • Physics Formulae
    • Motion
      • Speed = Distance/Time
      • Acceleration = Velocity/Time
    • Forces
      • Weight = Mass x Gravity
      • Density = Mass/Volume
      • Extension = Length - Initial Length
      • Force = Extension x Constant
      • Force = Mass x Acceleration
    • Energy
      • Efficiency =  Output/Input
      • Work Done = Force x Distance
      • Gravitational Potential Energy = Mass x Gravity x Height
      • Kinetic Energy = 0.5 x Mass x Velocity²
      • Power = Energy/Time
    • Pressure
      • Pressure = Force/Area
      • Pressure1 x Volume1 = Pressure2 x Volume2
    • Thermal Physics
      • Thermal Capacity = Energy/Change in Temperature
      • Specific Heat Capacity = Energy/Mass (Change in Temp.)
      • Specific Latent Heat = Energy/Mass
    • Waves
      • Speed = Frequency x Wavelength
    • Light
      • Angle of Incidence = Angle of Reflection
      • Refractive Index = Speed of Light in Air/Speed of Light in Substance
    • Electricity
      • Charge = Current x Time
      • Electromagnetic Force = Energy Produced/Charge
      • Potential Difference = Energy Supplied/Charge
      • Resistance = Potential Difference/Current
      • Energy Transferred = Power x Time
      • Electrical Power Supplied = Current x Potential Difference x Time
      • Total Resistance (Series) = Resistance 1 + Resistance 2
      • 1/Total Resistance (Parallel) = 1/Resistance1 + 1/Resistance2
