Newton's Third Law: For every action, there is an equal and opposite reaction.
In the case of a box:
* Action: You push on the box with a certain force.
* Reaction: The box pushes back on you with the same force, but in the opposite direction.
Important Points:
* Equal Forces: The force you exert on the box and the force the box exerts on you are equal in magnitude.
* Opposite Directions: The forces act in opposite directions.
* Simultaneous: These forces happen at the same time.
Example:
Imagine you're pushing a heavy box across the floor.
* You push on the box (action).
* The box pushes back on you (reaction).
You feel the box's resistance as you push, and it's this reaction force that makes the box move.
