A force of 10 N moves an object 5 m in the direction of the force. What is the work done?
Correct answer: C. 50 J
- A. 15 J
- B. 20 J
- C. 50 J
- D. 100 J
Explanation
This is correct because work = force × displacement = 10 × 5 = 50 J.

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.
