Fundamental IGCSE Equations for the exam!
Speed = Distance/Time
Acceleration = Change in Velocity/ Time
Force = Mass x Acceleration
Weight = Mass x Gravitational Field Strength
Moment = Force x Perpendicular distance from pivot
Power = Current x Voltage
Energy transferred = Current x Voltage x Time
Voltage = Current x Resistance
Charge = Current x Time
Efficiency = Useful Energy Output/Total Energy Output x 100
Work done = Force x Distance moved in the direction of the force
Gravitational Potential = Mass x Gravitational Field Strength x Height
Kinetic Energy = 1/2 x Mass x Speed squared
Power = Work done/Time
