I was thinking about this today:
When a force acts on an object, the object exerts on equal and opposite force - Newton's third law. Imagine this situation:
I am breaking down a wall with a hammer. I begin hitting the wall gently and this wall doesn't break. I then hit harder and the force exerted on the wall increases. As I'm hitting the wall harder, the wall begins to crumble and break.
What I want to know is:
- Does the wall have a certain threshold value at which point it cannot exert a force opposite and equal to the force I hit with and begins to crumble? The harder I hit, the more I exceed its threshold value and the more it crumbles and breaks.
-Why does the wall not fall down completely if I exert a force just above this theorized threshold value? Is it due to friction forces in the planes of atoms? Is it due to the composition of the wall itself? Or is it due to the way atoms are arranged in the wall?
