Question | Answer |
Distance Travelled = x = | Average Speed x Time s x t |
Acceleration = a = | Change in Velocity ÷ Time Taken v - u ÷ t |
Force = F = | Mass x Acceleration ma |
Weight = | Mass x Gravitational Field Strength |
Efficiency = | (Useful energy transferred) ÷ (total energy supplied) |
Momentum = | Mass x Velocity |
Wave Speed = | Frequency x Wavelength |
Wave Speed (2) = | Distance ÷ time |
Density = | Mass ÷ Volume |
Work Done = | Force x Distance Moved in Direction of Force |
Change in Gravitational Potential Energy (GPE) = | Mass x Gravitational Field Strength x Change in Vertical Height |
Kinetic Energy = | 1/2 x Mass x (Speed)² |
Power = | Work Done ÷ Time Taken |
Energy transferred = | Charge Moved x Potential Difference |
Charge = | Current x Time |
Potential Difference = | Current x Resistance |
Power (2) = | Energy Transferred ÷ Time Taken |
Electrical Power = | Current x Potential Difference |
Electrical Power (2) = | Current ² x Resistance |
Force Exerted on a Spring = | Spring Constant x Extension |
Moment of a Force = | Force x Distance Normal to the Direction of the Force |
Pressure = | Force Normal to Surface + Area of That Surface |
