Question

Which among the following has same unit?

• A. Power and Pressure
• B. Power and Energy
• C. Work and Pressure
• D. Work and Energy

Answer 1

Answer:

D. Work and Energy

• Energy is what is lost or gained by doing work on an object or by the object.
• Therefore energy is required to produce work in an object.
• In other words, energy is the form of work that is stored and work is the one that is used.
• Therefore, work and energy, while not synonyms, are consistent with respect to the object.
• So they both have the same SI unit.
• The SI unit of energy and work is joule.
