Three students, A, B, and C attempted the experiment similar to the one described in the video. All three students are pulling the same weight along a vertical line, but applying different forces along the line of the motion of the weight. The weight is initially at rest, and moved by 4 meters by the students. For each student, the force-distance graph is shown above.

Which student did the most work?

Cannot tell from the information given

All three did the same amount of work

Force (N) 0 A 0 1 2 3 distance (m) Force (N) B 0 1 2 3 4 distance (m) Force (N) 0 0 1 2 3 4 distance (m)
