You carry a 20-N box 5 m horizontally across a room.The work you do is 100 N-m.

Question

Quizplus · Accepted Answer

The work done is found by multiplying the force applied by the distance moved in the direction of the force (W = Fd). Since the force applied is horizontal and the box is being moved horizontally, the angle between the force and displacement is 0 degrees. Therefore, the work done is:

W = Fd = (20 N)(5 m)cos(0) = 100 J

The unit for work is Joules (J), not Newton-meters (N-m). So, the given work of 100 N-m is actually equivalent to 100 J. Therefore, the statement is false.
