Which of the following pairs has the same units?
Work and Energy
The SI unit of both work and energy is the joule (J), because work done is defined as force times displacement and it is equal to the amount of energy transferred to or from a body, so their dimensional formula is the same [ML²T⁻²].
Pressure is measured in pascal (N/m²) and force in newton, so they differ; force and work also differ (N versus J = N·m); power is in watt (J/s) which is different from pressure, so only work and energy share the same unit.
Hence, Work and Energy.
