Newton's 3rd law Flashcards
If Mr. Raupp and Mr. Haydamacker had a tug of war. Mr Raupp was pulling with 512N of force. Mr. Haydamacker was pulling with 512N of force. What does that mean.
Although the forces felt are equal, Mr. H has more muscle mass which is harder for Mr. Raupp to move. So Mr. H wins!
Which is the correct description of Newton’s 3rd Law of Motion?
If two objects collide, their forces will be equal in magnitude and in opposite directions on each other.
A car rolls down a hill and hits a mailbox. How would Newton’s 3rd law explain this interaction?
The mailbox and the car would experience equal impact force.
If Mr. H was pushing on you with 200N of force and you moved backwards that means…..
You are also pushing with 200N of force back on Mr. H.
If Mr. H was pushing on you with 222N of force and you moved backwards that means…..
You pushed back with 222N of force on Mr. H.
You are hanging from your door jam, describe the forces between those two objects.
The door jam and you hands experience the same force but in opposite directions of each other.
When a basketball hits the classroom floor, describe the forces and motion that occur.
The floor and the basketball experience the same force, but the ball is less massive so the force moves it easily.
A skate boarder loses his balance and hits a stop sign. The skateboard applies a force of 400N to the stop sign. What would Newton’s 3rd Law of motion also state?
The stop sign applied 400N of force back on the skateboard.
A Semi Truck windshield strikes a large moth while traveling at 50km/hr…SPLAT! What does Newton’s 3rd Law tell us about that interaction?
Upon impact, the moth and the windshield experienced the exact same amount of force.
How does Newton’s 3rd Law explain Mr. Raupp sitting still on a chair?
The upward push force of the chair is the exact same amount of force as Mr. Raupp’s downward force due to gravity.
If you push on the wall with 234N of force and you hands break through the wall what does that mean?
The impact force of 234N was the same for both, but the wall was too fragile to handle that force and broke.
If I was in space and accidentally started floating away from the space station while working with and carrying a huge/massive solar panel, how could I make my way back to the ship using my knowledge of Newton’s 3rd Law of Motion?
Put your body between the solar panel and the station. Push the solar panel away from the station as hard as you can which will force you to float towards the space station.
You throw a pumpkin at a wall just to see what would happen. Which options is correct….
The pumpkin and the wall experienced the exact same force upon impact.
A tennis racket smacks a bowling ball traveling at 5m/s with a force of 155N. What would the force be with Newton’s 3rd Law of Motion in mind? (You know the law, don’t over think it!)
The bowing ball would experience 155N in the opposite direction it was rolling from the tennis racket.
