luuuu:

The same force is applied to two skateboards. One rolls across the room and the other moves a few feet and comes to a stop. Where was there more work done? The skateboard that traveled the shorter distance shows more work because there was more resistance. The skateboard that traveled the longer distance shows more work because it was lighter. The skateboard that traveled further shows more work because the distance was greater. The skateboard that traveled the shorter distance shows more work because the force was greater.

Are you doing force and motion in science

Vocaloid:

Old question but will respond so this can be closed This is a somewhat poorly worded question (there's two forces, and therefore two types of work to consider: the work done by the pushing force, and the work done by friction). However, I've done a bit of sleuthing on this question and it seems like they just want you to consider work = force * distance for the pushing force. So consider which skateboard has a higher force*distance.
