1. Speed:Speed = Distance ÷ Time
2. Acceleration:Acceleration = (Final velocity – Initial velocity) ÷ Time
3. Force:Force = Mass × Acceleration
4. Weight:Weight = Mass × Gravitational field strength (g = 9.8 or 10 N/kg)
5. Momentum:Momentum = Mass × Velocity
6. Work Done:Work Done = Force × Distance (in direction of force)
7. Kinetic Energy:Kinetic Energy = ½ Mv square
8. Gravitational Potential Energy (GPE):GPE = Mass × g × Height = mgh
9. Power (Energy):Power = Energy ÷ Time
10. Power (Work Done):Power = Work Done ÷ Time
11. Efficiency:Efficiency = (Useful Energy Output ÷ Total Energy Input) × 100%
12. Density:Density = Mass ÷ Volume
13. Pressure (solid):Pressure = Force ÷ Area
14. Pressure (liquids):Pressure = Density × g × Height
15. Ohm’s Law:Voltage = Current × Resistance
16. Electrical Power:Power = Voltage × Current
17. Charge:Charge = Current × Time
work = force * distance
