- 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
- Motion
