Work is a:
Correct answer: B. Scalar quantity
- A. Vector quantity
- B. Scalar quantity
- C. Sometimes scalar sometimes vector
- D. None of these
Explanation
Work has only a magnitude but no direction. The formula for work is written as a dot product of force and displacement. Therefore, work is a scalar quantity.

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.
