Which statement describes how this example is an application of newton’s laws of motion? according to newton’s first law of motion, the balloon continues moving until the forces on it are balanced. according to newton’s third law of motion, the balloon is pushed forward as the air is forced out. according to newton’s third law of motion, the balloon resists any change of motion unless an unbalanced force acts upon it. according to newton’s second law of motion, the balloon exerts a force on the air, which exerts a force back on the balloon.
