Physics Equations
All of them!
Name | Equation |
---|---|
Density(kg/m3) = | Mass (kg) / Volume (cm3) |
Distance Travelled (m) = | Speed (m/s) X Time (s) |
Acceleration (m/s2) = | Change in velocity (m/s) / Time (s) |
Kinetic Energy(J) = | 0.5 X Mass (kg) X Speed (m/s) |
Force (N) = | Mass (kg) X Acceleration (m/s2) |
Momentum (kgm/s) = | Mass (kg) X Speed (m/s) |
Work Done (J) = | Force (N) X Distance (m) |
Power (W) = | Work Done (J) / Time (s) |
Force exerted by a spring (N) = | Extension (m) X Spring Constant (k) |
Weight (N) = | Mass (kg) X Height (m) |
GPE (J) = | Mass (kg) X Gravitational field strength (g) (N/kg) X Height (m) |
Charge Flow (C) = | Current A) X Time (s) |
Potential Difference (V) = | Current (A) X Resistance (Ohms) |
Energy Transferred (J) = | Charge (C) X Potential Difference (V) |
Potential Energy (W) = | Potential Difference (V) X Current (A) = (Current (A))2 X Resistance (Ohms) |
Power (J,kWh) = | Power (W, kW) X Time (s, h) |
Wave Speed (m/s) = | Frequency (Hz) X Wavelength (m) |
Energy Transferred (kWh) = | Useful energy transfer (J) / Input energy transfer (J) |
