Question
In physics, what is the definition of work done by a constant force on a particle moving in one dimension?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Work done by a constant force is defined as the product of the component of the force in the direction of the displacement and the magnitude of the displacement. Mathematically, for one-dimensional motion, W = F_x Δx, where F_x is the force component along the displacement Δx.
Hint
Recall that only the component of force parallel to the motion contributes to work.
