- The rate of work done is called power.
- It is denoted by P. The SI unit of power is the watt (W).
Power (P) = W / t
W = work done
t = time
EXPLANATION:
Dimensions of force is \(ML{T^{ - 2}}\).
Energy or Work done = Force × Distance
Dimensions of energy is \(M{L^2}{T^{ - 2}}\).
The dimensions of power = (Dimension of work) / Time (t) = (\(M{L^2}{T^{ - 2}}\))/T = \(M{L^2}{T^{ - 3}}\).
