Answer 1

Answer:

A balloon provides a simple example of how a rocket engine works. The air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the "action"; the movement of the balloon forward is the "reaction" predicted by Newton's Third Law of Motion.

2.Standing on the ground, you push on the ground with a force due to gravity (Fg down) and the ground pushes back on you (FN up). ... Without it there would be a net force down on you and you would accelerate down. This is an example of an action-reaction pair, two forces that are equal but opposite to each other.
