Question

No work is done when we push immovable objects like a huge stone or a wall etc. However, we feel tired in doing so. Explain why?

Answer 1

Explanation

1. We get tired quickly when we push immovable things like large stones or walls, even if the work done appears to be zero because there is no displacement.
2. There is no doubt that we have not done any work on the object.
3. However, the effort we put into our bodies is not insignificant.
4. Our muscles are stretched, our blood is shifted to the strained muscles, and energy is wasted as a result of these displacements.
5. We are exhausted as a result of this lack of vitality.
