When we apply force to a heavy stone why does it not move???
Answers
Answer:-
▪️In the simplest situation, it simply bounces off. You throw a ball at a wall, it bounces off. No energy is transferred to the wall. The wall meets the ball with equal and opposite force, sending the ball back in the direction it came.......✍️
▪️You do need to be careful with the numbers here. To apply force and not have it move at all, then it needs to be not just "heavy" but "infinitely heavy". Real world objects appear not to move, but that's too simplistic: real walls aren't infinitely stiff nor infinitely heavy.......✍️
▪️In a less simplistic situation, the ball and the wall both deform somewhat when they collide. Some of this energy goes into the molecules of both objects, increasing their velocities and making them warmer. If the ball is made out of a completely inelastic substance (say, a lump of clay, or a glob of water), all of the energy is transferred this way......✍️
▪️If the object applying the force is a human body, the situation is even more complicated. Muscles aren't simple force-appliers; they are a collection of muscle cells that are continually pulling and releasing. They burn energy even when standing completely still. If you're pushing against a wall, or holding up a book at arm's length, they are converting chemical energy into heat, depleting your reserves and building up molecular waste products that you perceive as "being tired".....✍️
▪️That's a very far cry from the straightforward force diagrams that apply in the first scenario. Words like "force" and "energy" are still used to describe them, but the colloquial uses of these terms are very different from the scientific ones and the conservation laws do not apply at that level. If you can follow all of the forces down to the chemical level, however, you can apply the scientific definitions and everything still works...✍️
