Question

Force F applied on a body moves it through a distance S along F. The energy spent is ______.

Options

• F × S

• F/S

• FS²

• F/S²

Answer 1

Force F applied on a body moves it through a distance S along F. The energy spent is F × S.

Explanation:

Energy spent = work done = \[ W = F \times S \cos 0^{\circ} = FS \]. Other expressions do not have the dimensions of work.
