Power

Share:

Power is defined as the Rate of doing Work. i.e. ,

                                                 Power(P)= Work(W)/ Time(t)

Power can also be defined as the product of Force and Velocity. i.e. ,

                                                Power(P)= Work(W)/Time(t)
Since, 
                 Work(W)= Force(F) x Displacement(d)
Therefore, 
                 Power(P)= Force(F) x Displacement(d)/Time(t)
                                 = Force(F) x(Displacement(d)/Time(t))
   As, Displacement x Time= Velocity
                 Power(P)= Force(F) x Velocity(V)
Note:
Power is a Scaler quantity.
