What is the SI unit of work?
Correct answer: A. Joule
- A. Joule
- B. Newton
- C. Watt
- D. None of these
Explanation
The SI unit of work and energy is the joule (J). Joule is defined as the work done by a force of one newton causing a displacement of one meter. 1J = N/m

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
