v=d/t
Speed = Distance/Time
a=(v-u)/t
Acceleration = Change in Velocity/ Time
F=ma
Force = Mass x Acceleration
W=mg
Weight = Mass x Gravitational Field Strength
M=Fd
Moment = Force x Perpendicular distance from pivot
P=IV
Power = Current x Voltage
E=IVt
Energy transferred = Current x Voltage x Time
V=IR
Voltage = Current x Resistance
Q=It
Charge = Current x Time
Efficiency Equation
Efficiency = Useful Energy Output/Total Energy Output x 100
W=Fd
Work done = Force x Distance moved in the direction of the force
GPE=mgh
Gravitational Potential = Mass x Gravitational Field Strength x Height
KE=1/2mv2(squared)
Kinetic Energy = 1/2 x Mass x Speed squared
P=W/t
Power = Work done/Time
Vs/Vp=Ns/Np
Transformer equation
