![]() These are just a few examples of working models that can be created to demonstrate Newton’s laws of motion. The balloon should push the straw away, demonstrating that for every action there is an equal and opposite reaction. Hold the straw near the balloon and blow air into the balloon. Newton’s third law: To demonstrate Newton’s third law of action and reaction, you can create a model of a rocket using a balloon and a straw. ![]() When you release the air from the balloon, the straw should propel forward, demonstrating that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. Blow up the balloon and attach it to the straw.
