PHYSIC 300 LAB Report - Coursework Example A taut monofilament, which ran to the other end of the room, was threaded through the straw attached to the balloon. This was followed by releasing the hand-sealed balloon opening to launch the balloon into motion. The speed of the balloon was noted. The experiment was, respectively, repeated with ten pennies and ten Yen coins. The results of the experiment, indeed, validated the law of action – reaction, which states that to every action there is always opposed and equal reaction due to conservation of momentum. Simply put, if a body A exerts a force F on a body B, body B simultaneously exerts a force F of the same magnitude on body A provided both bodies are acting along the same line. Thus, as observed in our experiment, the balloon, by releasing the pressure inside, was launched into motion with a momentum that changes in proportion to the force exerted. The moving balloon exerted this force on the attached pennies/coin, as the case maybe. Following the law of action and r eaction, the pennies/coin exerted a force of the same magnitude on the balloon but in the opposite direction. We observed that as the number of the pennies increased from five to ten, which correspondingly increased the mass, the acceleration of the balloon decreased.
