Slow Motion Flipping Cat Physics | Smarter Every Day 58


Hey it’s me Destin Welcome back to SmarterEveryDay So you’ve probably observed that cats almost always land on their feet Today’s question is why. Like most simple questions there’s a very complex answer For instance let me reword this question How does a cat go from feet up To feet down In a falling reference frame without violating the conservation of angular momentum Now I’ve studied free falling bodies, my own in fact in several different environments and once i get my angular rotation started in one direction, I can’t stop it. Today, we’re going to use a high speed camera- we’re not going to use Alley because this is my daughter’s cat, i don’t want to hurt it- we’re going to use a stunt cat let me introduce you to Gi-Gi the stunt cat (music) I’ll just flip the uh, the video vertical and then motion track the cat it’s just going to take a lot more effort in post We’re going to try to do it in a way that doesn’t make anybody mad That’s pretty hard to do. You gotta drop the cat Ready Gi-Gi? Good kitty Checking out the high speed data there Gi-Gi? Ok the first thing a cat does when it’s falling is try to figure out which way is up. It does this either with the gyro in the ear or with its eyes Ready to talk cat physics? Alright. So check out this footage i captured with the Phantom Miro While Gi-Gi goes to get a drink of water. So here’s what’s interesting about this to me. You’ll notice that at the beginning of the drop the cat is not rotating halfway through the drop the cat is rotating and at the very end Gi-Gi somehow stopped rotating Newton’s law says an object at rest will stay at rest unless acted on by an external force I see no external forces on this cat So what’s happening here? It’s not making sense to me O.K. so in order to really get the right data we’re going to have to drop her 90 degrees out of phase. Atta girl This time watch her tail 3 2 1

  1. Its very obvious why, even the egyptians knew this, cats are gods and they use their powers to turn in the air and use their godly bodies to absorb the fall.

  2. Me: Hey i know how to improve your parkour skill like being able to jump off a high building, science approved!
    Parkour pro wanna be: Really? Im ma jump right now-
    'Arms breaking'

    P.P.W.B.: You said it's science approved.
    Me: Well since we are bipedal mammals our arms are 3 times weaker than our legs-
    P.P.W.B: Son of a-

  3. For some reason I thought he was gonna be taking cats and just forcefully twirling them through the air. I mean, I'm glad he didn't for the cats' sake, but that's a funny image to me.

  4. This video was bound to make some people upset, but the cats seem fine to me. At least you don't use them like animals for experimentation purposes on a regular basis and keep them in cages and feed them foods with viruses or drugs or whatever else like lab rats. That seems a bit more abusive to me than something like this. Just don't force the cats to keep doing it when they get upset with it like the black one did.

  5. Dude you should stop doing this
    It’s could possibly be hurting your cat and it looks like you are having fun hurting your cat for money

  6. What happens if you spread peanut butter on the cats back? Toast always falls peanut butter side down, so it stands to reason that the two forces should cancel each other out and the cat should spin in the air for eternity!

  7. The most amazing part of this video isn't the physics of a cat stopping it's self mid spin to land on it's feet. Cats always land on their feet everyone knows that. It's how you can get the cat to be so calm and still come back to you after grabbing it by it's feet and hanging it up side down. I tried this with my cat and just grabbing both her feet resulted in scratches and her not comeing within 5ft of me still and it's been 7 years since I did it.

  8. Almost always. Don't test it.
    Had a cat that was dropped, didn't land right. Tore all of the tendons in one leg.
    The Amazing Cat!

  9. So, if you spend two hours in Facebook, you inevitably end up learning about cat physics. I think that's a sure sign it's time to get off. (Before the crackhead throwing computations begin.)

  10. Interesting, What is the minimum in height this cat is able to complete full rotation? 2.5'- 3'. figured the tail was more of a factor.

  11. "Right now, we are playing fetch". Funny. It looks more like you are throwing the ball. The cat runs after it. You run after the cat who is guarding the ball so, it doesn't run away.

  12. 1:13
    The cat:OH BOI WHEN YOUR ASLEEP IMMA SHI* ALL OVER THE HOUSE BECAUSE OF thiiiiiiiiiiiiiiiis plomp lucky I survived that hooman

  13. Not everyone watching this video an now attempting to drop cat from different hights or the many kids that watch ur videos now trying this an not having the sence of….. securty measure's put in place for the animal!!!
    I do enjoy your videos and I like your idea behind this but not the smartest thing to do by using a real cat in action filming it for others to try especially people who are not the most sensible people! This was not a very well-thought-out video I must say your others are fantastic a lot of stupid people in this world that will attempt this and an animal get hurt cuz of it!!

  14. I'm just dying at the fact that he said he doesn't want to hurt the stuffed animal but then spends 6min showing us videos of him dropping cats lmfao. I have a feeling that black cat didnt get his overtime paid. Hahaha. I found this channel 2 weeks ago from a YouTube recommendation. It's great! I'm sure kitties were fine.
