Question

Give the SI unit and dimension of work, energy and power.

Answer 1

SI unit of work = joule (J)
SI unit of energy = joule (J)
SI unit of power = watt (W)

Dimensional formula of work $=M{L}^2{T}^{-2}$
Dimensional formula of energy $=M{L}^2{T}^{-2}$
Dimensional formula of power $=M{L}^2{T}^{-3}$
