A force F moves a body through a displacement S in the direction of the force. What is the work done by the force?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → \(F \times S\)
Work done by a constant force is the force multiplied by the displacement in the direction of the force. Here the whole displacement S is along F, so W = F × S, measured in joules. The work would be zero only if the displacement were zero or at right angles to the force.
