Newton's Third Law
Easyphysics
When you push a wall and it does not move, which is true?
Select the correct option:
Solution
Incorrect! Answer:
You exert a force and wall exerts equal opposite force on you.
Newton's Third Law states that every action has an equal and opposite reaction.
- When you apply a force F on the wall, the wall simultaneously applies a force −F back on you.
- These two forces constitute an action-reaction pair. They act on different bodies (you and the wall) and therefore do not cancel each other out on a single body.
- The wall doesn't move because your force is balanced by the internal stresses and the attachment of the wall to the ground/Earth, but the reaction force on you still exists.
