Dope Tech Episode 2

<<@sumitrai666 says : I have that phone the iPhone 5>> <<@deathbeforebeginning says : Tennis rack physics duh>> <<@Game_N_Gear says : The stuff inside the phone has an uneven weight distribution>> <<@Example1080 says : Gyroscopic motor>> <<@SuryaCherukuri-s9u says : Tennis racket theorem>> <<@BrickByBrickVets says : I wish the video wouldn’t pause everytime my phone bounced off the floor, while trying to watch this.>> <<@PavanSegoju says : Dzhanibekov effect>> <<@Ray_of_Light62 says : Consider that each solid object has three axes of rotation, and each axis has a different moment of inertia. The Dzhanibekov effect is a principle in classical mechanics proving that spinning a 3-dimensional rigid object around its primary axes of inertia is stable for the highest and lowest axes, but highly unstable for the intermediate (middle) axis. This instability of the rotation around the middle axes is also known as the "Tennis Racket Theorem". Greetings, Anthony>> <<@AdorableFilterr says : Phone repair station revenues after this short 📈📈📈>> <<@YITTRIUM_Band says : thats why we call it an impossible in skateboarding>> <<@KrsnaSevaka1008 says : Because you are not skilled enough to do it..?>> <<@Dicemann555 says : This is how skateboards tre flip or 360 flip. Controlling chaos>> <<@JasiufromChicago-NCP says : Holy cliffhanger>> <<@miguelm203 says : Tennis racket theorem 🙌>> <<@prfmzagnut says : The iPhone 5 shows how old this clip is>> <<@psurob14 says : I would assume because the weight is off center in that direction.>> <<@SNNNKY says : I'm tired of answering his questions.>> <<@superjeffcentola4945 says : I just did a few clean flips. Just spin it really fast with even pressure. Wasnt that hard>> <<@_EyeOfTheTiger says : Back in the day this channel wasn’t owned by venture capitalists>> <<@Vedisingh2247 says : Due to Angular Momentum. This phone contains inconsistent density changing it's mass center>> <<@The_Original_Forrest_Trump says : Space Lasers from the Ark of the Covenant reflecting off of heaven hit your phone with holy photons.>> <<@ScarletRaven-r7g6z says : Poor guys couldn't wait long enough to wait for the explanation and ended up breaking their phones.>> <<@oldsalt394 says : Camera technology being concentrated into a corner greatly influences angular momentum. The weight of the battery close to your your hands makes you think the weight of your device is symmetrical, but if you try to balance your phone on your finger, you'll find you are no where near the center. Conclusion, weight on the corner make phone flippy flip and monkey brain stupid.>> <<@prabhatracherla3098 says : I've a life, so sorry hard pass>> <<@Ty-Refyned says : I just tested it and my phone spun perfectly all 3 ways when I tossed it in the air>> <<@adaptivebitsjsc.3263 says : That's just a Tre flip.>> <<@MavaniMalay says : weight is uneven>> <<@Pro_max5 says : I wonder how many people had broke their phone after this 🔥>> <<@CatalinaMonicaStan-d5j says : When they torch your cam and QR>> <<@yungsoohong28 says : Because the initial direction vector is the cross procdect of X cross Y. It is the dirction Vector along the thtough path. And XY will only rotating to its inertia which is the cross produuct vector zero point.>> <<@xenter7106 says : I aint doing ts💔>> <<@Darkstalker-hc5go says : “Why does this happen?” THATS THE REASON I CLICKED THIS IM ASKING YOU>> <<@allagovind5588 says : Ever heard of center of gravity?>> <<@SujiwoteJo-v7o says : Cause the weight is not equaly spead across the case>> <<@FieryVigil says : My phone just kinda does flip normally in that direction so ig I'ma just skip the video lol>> <<@hiimnln says : If you're wondering why this happens it's because 1. Phones aren't built perfectly balanced 2. You'd need to flip the phone perfectly straight, which is really hard to do>> <<@SuperMario1977-f1x says : nice video>> <<@ShaheenBegum-w5o says : Hi i have so many ideas>> <<@Vespergleam says : I've tried and I can spin it in all three ways you've showed.>> <<@KougaJ7 says : Only 2 years ago? Derek looks so young here.>> <<@Basil-g5w says : U sure about that>> <<@cHAOs9 says : oh damn he said it was IMPOSSIBLE? i just did it perfectly a few times. well, so, looks like i have magic powers! ima go try jumping off the roof now...>> <<@cHAOs9 says : because the angular momentum makes narrow rotation WAY faster. similar to the wingnut in zero-g. but you CAN flip it perfectly flat end to end. you just have to do it with almost 0 sideways rotation. i did it multiple times just now to confirm.>> <<@LiaBeltran-my4bz says : Because it hits the air, is hard to something to move like that on his own>> <<@thetruthmovement2964 says : In this video, Derek Muller from Veritasium demonstrates a phenomenon known as the Intermediate Axis Theorem (or the "Tennis Racket Theorem"). While you are correct that an object in motion follows the laws of inertia (Newton's First Law), the reason the phone "wobbles" or rotates uncontrollably when flipped end-over-end has to do with its moment of inertia along different axes. How it Works: A rectangular object like a phone has three principal axes of rotation: The Longitudinal Axis (Long way): Spinning the phone like a top. This is stable [00:00]. The Transverse Axis (Short way): Spinning it like a coin on a table. This is also stable [00:05]. The Intermediate Axis (End-over-end): Flipping the phone across its middle. This is unstable [00:11]. When you try to flip the phone end-over-end, even the tiniest imperfection in your throw or a slight gust of air adds a small amount of rotation to the other two axes. Because the intermediate axis is inherently unstable, these small "errors" are amplified, causing the phone to twist and turn mid-air rather than performing a clean flip [00:18]. It isn't necessarily that the person can't throw it correctly—it's that the physics of a rigid body makes a perfectly stable rotation on that specific axis mathematically and physically impossible in a real-world environment.>> <<@dislikebutton8965 says : I guess we'll never know 🫳🎤>> <<@fx-DeadBeing says : Because the weight inside the phone is unevenly built. I guess.>> <<@Sergiu-e6b says : You are starting to piss me off.>> <<@igorigorev6566 says : Also works on tennis rackets and wing nuts, scientifically proven btw>> <<@EFDFABT says : It’s called a hardflip>>
