Question

A person try to push a wall hardly.What will be the work done on the body. Explain briefly.​

Answer 1

Answer:

Work done will be 0 because the distance and displacement covered by the wall when we push a wall is 0. We do exert some force on the wall but it is not enough to move it from one place to another. Hence the work done when you push a heavy cemented object such as a wall is 0.

Answer 2

Even though the man exerts force on the wall , the wall does not move. Work done = force applied * displacement and since the displacement of the wall is zero. , work done is also zero.
