Question

Examine the scenarios.

Scenario W: A force of 75 N moves a box 15 m.
Scenario X: A force of 100 N moves a box 12 m.
Scenario Y: A force of 50 N moves a box 20 m.
Scenario Z: A force of 25 N moves a box 45 m.

In which scenarios is the same amount of work done on the box?

W and X
W and Z
X and Y
Y and Z

Answer 1

Work = force × distance.

W: 75 N × 15 m = 1125 J
X: 100 N × 12 m = 1200 J
Y: 50 N × 20 m = 1000 J
Z: 25 N × 45 m = 1125 J

So W and Z have the same work done.
