Is work and energy equal?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Work and energy are closely related but not identical. Work is the process of transferring energy, while energy is the capacity to do work. According to the Work-Energy Theorem:
- Work done on an object equals its change in kinetic energy
- W = ΔKE = KE_final - KE_initial
- Energy is conserved; work transforms it from one form to another
Both share the same unit (joule) and are scalar quantities.
