For a particular displacement, how is the work done related to time?
Correct answer: B. It is independent of time
- A. It depends on time
- B. It is independent of time
- C. Both of these
- D. None of these
Explanation
The work done on an object is given by the equation: W = Fd cosθ where W is the work done, F is the force applied, d is the displacement, and θ is the angle between the force and displacement vectors. From this equation, we can see that the work done depends on the displacement and the force applied. It does not depend on time.

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.
