Question #270825
15. A group of construction workers push against a large crate, trying to get it to move, but failing. Another coworker pushes a much smaller box and boasts he did more work. Is this true?
A. No, because he exerted less force.
B. No, because he moved an object with a smaller mass.
C. Yes, because he did the work alone.
D. Yes, because the small box moved, while the big box did not.
Expert's answer
Yes, because the small box moved, while the big box did not, while work is force times displacement.
