Question

If you push a wall , but it does not move . No work is done., justify the answer

Answer 1

Answer:

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.

Answer 2

Yes , if you push a wall then It does not move because it is fixed at a place and the force used to push a wall is not enough to push it.

so we can say that when we push a wall we are actually not doing any work ..
