B. But it depends on what side they are on.

Lincoln · Answer 2

Both of the brothers performed work. The one who pushed with a greater force did more work, and it had a positive sign. The one who pushed with a smaller force did less work, and it was also technically "negative" work, because the motion of the fridge was in the direction opposite to his force.

Now that THAT's settled, they ought to quit fridging around, and get that thing moved like their father asked them to do.
