Question | Answer |
GPE = | h x m x g Height x Mass x Gravitational Field Strength |
Power = | V x I Voltage x Current |
Voltage = | I x R Current x Resistance |
Energy = | V x I x t Voltage x Current x Time |
Efficiency (%) = | (useful energy out ÷ total energy in) x 100 |
Work done = | F x D Force x Distance |
Power = | F x s Force x Speed |
Power = | E ÷ t Energy ÷ Time |
Speed = | D ÷ t Distance ÷ Time |
Acceleration = | (v - u) ÷ t Change in velocity ÷ time |
Force = | m x a Mass x Acceleration |
Weight = | m x g Mass x Gravitational Field Strength |
Momentum = | m x v Mass x Velocity |
Density = | m ÷ v Mass ÷ Volume |
Pressure = | f ÷ a Force ÷ Area |
Moment = | F x d Force x perpendicular distance from pivot |
Force = | k x e Spring constant x extension |
KE = | 1/2 x m x (v x v) 1/2 x mass x (velocity x velocity) |
