Newton's laws are three fundamental principles of physics that describe the motion of objects. They are: 1) an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an external force, 2) force is equal to mass times acceleration, and 3) for every action, there is an equal and opposite reaction.
A balloon at rest will stay at rest until acted upon by an external force, such as air being blown into it. Once the balloon is inflated, it will stay in motion unless acted upon by an external force, such as the force of gravity pulling it back down.
Newton's second law states that the force applied to an object is equal to its mass times its acceleration. In the case of a balloon, when air is blown into it, the force of the air molecules hitting the inside of the balloon causes the balloon to accelerate and expand.
Newton's third law states that for every action, there is an equal and opposite reaction. When air is blown into a balloon, the air molecules inside the balloon push back against the walls of the balloon, causing it to expand. This is the equal and opposite reaction to the force of the air molecules hitting the inside of the balloon.
When a balloon is released, the force of gravity pulls it down while the force of the air molecules inside the balloon pushes it up. This demonstrates Newton's first law, as the balloon will continue in motion until acted upon by an external force. It also demonstrates Newton's second law, as the force of the air molecules pushing up on the balloon is equal to the mass of the balloon times its acceleration. Finally, it demonstrates Newton's third law, as the force of the air molecules pushing up on the balloon is equal and opposite to the force of gravity pulling it down.
