WorksheetsPerformance Quiz | MythBusters Crash Test
Total questions: 11
Worksheet time: 6mins
Now that we’ve watched the full MythBusters video and developed a model that explains what happens when two cars collide at 50 mph (Performance Task | Modelling a 50 mph Collision), we can use our model, observations and knowledge of Newton’s Laws to answer questions about collisions.
GOT IT!
I don't get it.
In the initial collision, which car had the most damage/wreckage after crashing into/colliding with a wall?
The red car (50 mph) had the most damage/wreckage
The yellow car (100 mph) had the most damage/wreckage
How did the red car and the yellow car look after they collided with each other 50 mph?
The cars looked very similar to each other, the damage was pretty much the same on each car.
The cars looked very different from each other, the damage was noticeably different on each car.
Did the cars look more like the yellow car or the red car after they collided with each other at 50 mph?
The cars looked more like the yellow car
The cars looked more like the red car
Which one of Newton’s Laws explains why the cars looked like they did after the collision?
Newton’s First Law (Inertia)
Newton’s Second Law (F=ma)
Newton’s Third Law (Action-Reaction Pairs)
Now imagine if the cars had different masses! What if one of the cars was not 1.5 tons. Imagine we filled the yellow car with bricks (.25 tons) and made it travel at the same speed (50 miles per hour) towards the red car carrying no bricks? Which car takes more force to travel (accelerate)?
Yellow car (1.5 tons + .25 tons of bricks)
Red car (1.5 tons)
If the yellow car had .25 tons of bricks would the cars look similar after colliding with each other at 50 mph?
Yes
No
Which car would have more damage/wreckage if the yellow car had .25 tons of bricks?
The yellow car would have more damage/wreckage
The red car would have more damage/wreckage
What would we have to do to the red car so that it would have the same damage/wreckage when colliding with a yellow car with .25 tons of bricks?
We would have to add more mass to the red car
We would have to less mass to the red car
What else could we do to the red car so that it would have the same damage/wreckage when colliding with a yellow car with .25 tons of bricks?
We could also slow the red car down
We could also speed the red car up
Which one of Newton’s Laws explains why changing the mass or the speed of the car changes the amount of damage/wreckage?
Newton’s First Law (Inertia)
Newton’s Second Law (F=ma)
Newton’s Third Law (Action-Reaction Pairs)
