3.
John pushes a chair up a ramp into a moving truck. Sally lifts the chair straight up to the moving truck. Sally says that he is doing more work because lifting the box takes more energy. Is Sally correct?
a)
Yes, using more force to move an object does more work.
b)
No, John is doing more work because he has to travel farther to move the box up the ramp.
c)
No, they are doing the same amount of work because their force multiplied by their distance is the same.
