Work done and energy transfer
Question
- A. The energy transferred when a force moves an object through a distance
- B. The total energy stored in an object
- C. The force applied to an object without movement
- D. The distance an object travels without any force applied
Answer
The energy transferred when a force moves an object through a distance
Explanation
Work done is defined as the energy transferred when a force acts on an object and moves it through a distance.
Common mistake
Confusing distance with displacement
Students often think the distance moved along the line of action of the force is the same as the straight‑line displacement between start and end points, even when the path is curved or the force changes direction.
Remind that the distance used in the work‑done equation is the total length travelled along the line of action of the force, not the vector displacement. If the force is applied along a curved path, add up the small straight‑line segments of that path to get the correct distance.
