**These are conceptual questions, and i just want to really understand why the answer is the answer!**

1. Homework Statement

1. Homework Statement

1) A force acts to push two boxes, box 1 and box 2, across a floor (assume for this problem that friction is negligible). The two boxes are stacked such that the force directly acts on box 1 and box 1 exerts a force that pushes box 2. How does the force of box 1 on box 2 compare to the directly applied force?

2)If an object of mass m is hanging from a rope with weight w, what is the difference between the tension at the top of the rope (the part not connected to the object) and the bottom of the rope (the part connected to the object)?

## Homework Equations

Action-reaction

Tension

## The Attempt at a Solution

1) So, i was thinking that this problem has to do with the action-reaction law (Newton's 3rd law). Since the applied force on box 1, could i say that box 1 is applying the the same force on box 2 as the applied force?

2) I was thinking for this one that the bottom of the rope would be the weight of the object, but I'm not sure if this is right. What can be said about the difference?
