Please help rewrite my answer to a question of Newton's third law of motion:
Q: You blow up a balloon and pinch the open end closed. Predict what will happen when you let go of the balloon in terms of Newtons' third law of motion
When the balloon is let go of, the balloon will use its elastic potential enery to create an action force that propels air backwards, and a reaction force is created that pushes the balloon forward.
Newton's third law states that when two bodies interact, with the first body exerting a force F on the second, the second body also exerts a force with an equal magnitude on the first. The direction of the two forces is opposite to each other.
When air is filled in the balloon, it expands with a potential energy getting stored in the skin of the balloon that is capable of being stretched. Providing an exit for the air to escape converts the potential energy stored in the skin of the balloon to kinetic energy of the air. As the air is pushed out with a force exerted by the balloon, it exerts a force equal in magnitude and opposite in direction on the balloon. This force pushes the balloon in a direction opposite to that in which the air is escaping.
The force exerted on the air which pushes it out can be referred to as the action and the force it exerts on the balloon is the reaction.
