D. FORCE Now let’s talk about FORCE. Mass changes things. The bowling ball & the soccer ball have different masses. They may hit the ground at the same time when dropped because they have the same equal amount of force pulling on them, but which ball will HIT THE GROUND with the greatest amount of FORCE– the bowling ball or the soccer ball? The _______________________ weighs the most because it has more mass. Therefore, the ____________________ would hit with the greatest amount of force. PHYSICS EXPLAINS KARATE! Could you break 3 bricks in half with just your hand? Not me! But a karate master could! He uses Newton’s 2nd Law - Force = Mass x Acceleration. The karate master trains for years to focus on using his entire body’s MASS and ACCELERATES that mass to create enough FORCE to break 3 bricks. Acceleration is the Key! Force = Mass x Acceleration F=MA Mass FORCE = Human Hand & Forearm X .75kg FORCE = 3550 N of Force Acceleration 50 m/s
Now let’s look at a train and a bullet. Which has the most mass – a train locomotive or a bullet? So, we naturally think the train, being the biggest and heaviest, would cause the most damage. Right? BUT, when we accelerate ONE mass and not the other, things change. Force = Mass x Acceleration F=MA TRAIN BULLET Mass = 5000 lbs Mass = ½ lb Acceleration = 30 mph Acceleration = 30 mph Force = 5000 x 30 = 150,000 N Force = ½ x 30 = 15 N Going the same speed, which object would have the most force? ________________ Change the ACCERATION of the bullet and which object would have the most force? _________________________ TRAIN BULLET Mass = 5000 lbs Mass = ½ lbs Acceleration = 30 mph Acceleration = 500,000 mph Force = 5000 x 30 = 150,000 N Force = ½ x 500,000 = 250,000 N What changed the amount force? _________________________________
