Question
- A. One joule is one newton metre
- B. One joule is one kilogram metre per second
- C. One joule is one watt per second
- D. One joule is one newton per second
Answer
One joule is one newton metre
Explanation
One joule is defined as the work done when a force of one newton moves an object one metre in the direction of the force.
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.
