A box is supported by a 4.6 N vertical force and carried 2.3 m horizontally across a room at constant speed. Then, the same box is pushed 2.3 m horizontally across a smooth table (smooth enough to ignore friction) by a 4.6 N horizontal force. In which case was more work done on the box by the 4.6 N force? More work was done when the box was pushed across the table. More work was done when the box was carried across the room. The work was the same in each case, since the force and distance were of equal magnitudes in both situations.

A box is supported by a 4.6 N vertical force and carried 2.3 m horizontally across a room at constant
speed. Then, the same box is pushed 2.3 m horizontally across a smooth table (smooth enough to
ignore friction) by a 4.6 N horizontal force. In which case was more work done on the box by
the 4.6 N force?
More work was done when the box was pushed across the table.
More work was done when the box was carried across the room.
The work was the same in each case, since the force and distance were of equal magnitudes in both
situations.
