Question on: WAEC Physics - 2002
Which of the following statements correctly defines quantitatively the work done by a force? the product of the force and the distance moved
A
parallel to the line of action of the force from a reference point
B
perpendicular to the line of action of the force from a reference point

Ask EduPadi AI for a detailed answer
Correct Option: A
The quantity of work done (or energy converted) by a force, when the force moves, depends on two obvious factors:
- the distance moved (in the direction along which the force acts) and
- the magnitude (strength) of the force
