By popular demand I have shirts now! I picked the super soft, high quality shirts and make $0 on all items which is why they are priced so handsomely :)

Summary: To understand how mousetrap cars work you first need to understand the concept of mechanical advantage. There are 4 principles to win with a long distance car:
And 4 principles for winning with a speed car:
Finally, we visit the Science Olympiad to see these principles in action

The internet needs more people like Mark Rober. Youtube should give incentives for NASA employees to become creators.

Can you imagine how lucky some future kid is gonna be to be able to call Mark Rober their physics teacher??

no one is talking about how mark was outside IN THE RAIN for a bit just so he can explain the topic he was on. I want him to be my teacher.

The way Mark explains physics is not only easier to understand than school ever taught me but he makes it so much more interesting

- Dad, why is my sister called Rose?
- Because your mother loves flowers.
- Oh ok, thanks dad..
- No problem, Mechanical Advantage.

Itās almost 2022 and Iām still enjoying this video, I mean the way Mark explains engineering is so amazing.

this has sat in my brain for 3 years and has silently been supporting me through my physics classes. Thank you.

I wish Mark was my physics teacher...

Hey! That's me at 12:50 ! Super cool to see a Science Olympiad event highlighted on your channel! It was great to meet you and talk about my car.

in my 8th grade science class we are actually doing something where you can either build a lander or a rover, no electricity and stuff like that. I had the egg drop thing as an idea for a lander and this for a rover and I'm super excited to test both out and see which one is better.

I think I just found a lifetime hobby. Every science teacher Iāve ever had said I possess an extremely intuitive understanding of physics and this seems to be a perfect application of that. Just seeing this video makes my mind go crazy thinking of all the ways I could attempt to improve the design. I wonder if you could devise an equation that could predictably determine what the optimal ratio of mechanical advantage for a given car would be, accounting for factors like weight, wheel diameter, coefficient of friction on the wheels, axels, and every other moving part where friction is present. Obviously thereās a perfectly optimal car that could be made if you could fully understand all these factors and thatās what is most alluring to me.

Mark: But I could lift 10lbs 50 times.
Uses a 12 pound weight

I never did this as a kid but being an auto mechanic now I got a huge kick out of this video! Made me think about the mathematics of transmissions and differential final drive ratios. Super fun keep up the great work!

Wonderful! From your intro, I thought you were going to make your own design, better than any other. Even so, I enjoyed the lesson.

I learned more in the first 5 minutes than a whole semester in high school

The way he explained physics is so much better then the 9 years of science class I've taken

When we did this in highschool our speed/acceleration contest was only over a meter, so I just used the mouse trap to catapult my car over the finish line.
