      yeah damn I also studied Physics at A-levels and in every question, problem or case air resistance was assumed negligible but I always used to ask and knew it can't because when you take your hand out of a fast moving car your hand literally goes back but my teachers just said your life would become hell if we were to consider that. Till this day I do not get assuming it negligible because we studied projectile and imagine calculating something and doing it in real life and getting just some % of what you expected bcz of air resistance

    Why is it that when stood still on an electric scooter I fall over, yet when I'm moving I can balance fine. What is the forces at work to cause that??

    • Paul Gibbon
      Paul Gibbon 5 сағат бұрын

      @Roi Joleil cheers. I was wondering what forces are at play aswell and why it's much easier to balance while moving forwards.

    • Roi Joleil
      Roi Joleil 8 сағат бұрын

      Lets start with a pen. Try and place a pen on its tip on your table. It wont work because it only has 1 contact point. So even the slightest discrepancy will make it fall over (forward, backward left or right)
      A bike or scooter have 2 contact points. With 2 contact points it has stabilty towards 1 axis (front to back) but not side to side. So again any discrepancy will make it all over either left or right.
      The reason why bikes / scooters dont fall over while driving, or why you can balance a pen on your tip of your finger is because of the movement you apply to stabilize.
      If a pen on your finger starts falling forward, you move your finger forway. If it falls to the right, you move your finger to the right. This is why theoreticly you can balance a pen on your finger indefinetly.
      You are doing the same with your scooter. While driving you do an never ending amount of adjustments to stabilize. Try driving around with your scooter and pay attention to all the little turns you are doing. When you are driving forward you arent 'really' driving forward. you are driving left / right / left / right repeatedly.
      (how noticeable that is comes down to the width of your wheels. A motorcycle can have really wide wheels so that doesnt really happen there. A bike however has a much smaller width so you do it constantly)
      Everytime you fall to the left, you make an adjustment and steer to the left to stay upride.
      Basicly, the reason you fall over standing still but not while driving is because steering is how you balance on it. And Steering to my knowledge is difficult while stationary.

    I am 71 and never even passed my O’level maths, but found this fascinating, giving names to forces that I only intuited were there. Those experiments looked such fun, were such fun, because they were experiential, leading to unexpected outcomes. There is such joy in learning like this, seeking the “why?” Or “how come?” after the event. It is ultimately playful, it seems to me. Thank you!

      FWIW, most of my comment was informing others, and correcting a limited - and surprisingly# Murrrca centric - view. 🙂
      Also, if you feel victimised by a moment of 'punching up', then maybe the _social media_ aspect of the internet, isn't for you. 🤷🏼‍♂️

    Pennies may not be dangerous as they're not very aerodynamic and exactly how high was the copter? I guess it's gonna take a "Geezer" (well into my 70's) to give you some info. early in WWii "bomblets" with fins called Lazy dogs were introduced, fins and steel or lead (one I had in my hand at a surplus store was lead) and dropped from high altitude planes to incredible effect on troops, vehicles etc. They were used in the Korean War too. Here's another, during the building of bridges that were built with caissons into the water, (Brooklyn bridge) it was discovered injuries could happen when small heavy objects were knocked onto workmen in the caissons

    Trying to outrun a Thunderstorm in Texas on a motorcycle I was doing about 130mph when I drove directly into a wall of golf ball sized hail. My leathers and helmet helped a lot but I was still black and blue. I took a large one to my throttle hand before finding a bridge to sit under and it hurt so bad I could barely use it for a week. You can drop money on me anytime you like, but hail stones and tire weights being thrown through the air at well over 100mph is deadly.

    In 1983, I was walking near 55 Water street in downtown NY. All of sudden a large bolt, about half the size of a railroad spike, hit the ground in front of me. It took a tremendous chunk of concrete off of the sidewalk. I was shocked, I even froze, then I was rushed to the side by a stranger in case more bolts were coming down. People ran out of the way. We ended up across the street. It turns out that a construction guy, who was about 200 stories up, dropped the bolt. Not sure if it was an accident, or deliberate, as people can be both deliberate and accidental. Either way, there is no quetion that had I been hit, it would have killed me, and probably instantly. I think about this incident from time to time and it still makes me uneasy, even quesy. Pennies might hurt you, but there are far heavier things that people need to worry about, like construction tools or bolts! It's not like construction workers are going up with buckets of pennies.

    My thought has always been air resistance… but what about a aerodynamic weight, the weight of a penny?
    Would then weight make a difference?
    Is there also not a point in which it wouldn’t get any faster?
    Because it can only push as much as it’s own weight anyway?
    At what distance does a object reach its pinnacle speed?

    Glad to see this tested. My belief is that of course a penny wont hurt you too badly. A terminal velocity for a penny w/ air resistance would be somewhere around 120 mph. Prob the same speed as a baseball pitcher would achieve throwing one at you. It may sting and cause a welt but your life is not in danger. This same concept applies to bullets shot up into the air. Every year around New Year's Eve, the tv personalities will talk about "what goes up, must come down" and your life could be in danger from guns shot into the air at midnight. NOPE. A bullet is heavier than a penny but the same concept applies, it will fall at 120mph on the way down. Imagine a baseball pitcher throwing a bullet at you. It will hurt and cause a bruise but there is no way it will kill you.

      @onikin actually the potential energy would be 850 ~ joule if we don't consider air resistance (yeah...). Thats like a 25 kg (55lb) object falling on your head from 3.5 metres (11.5 feet)

      Might not kill though because the pounds per square inch might be comparable to a penny. Lethality to penetrate the body is more about density than weight. That's why bullets are pointy and made of lead. It would give you a hell of a bigger and more painful bruise though.

    Bullets wanting to fall on their side actually makes a lot of sense to me. Because if you have less resistance, it's easier to throw an object off balance, right? Like how it's harder to balance a pen on your finger on the point of the pen than it is to balance it on its side. If you have an object falling and there's minimal resistance, any small amount of cross wind-esc force is going to move the back end of it (which is experiencing less resistance than the front (the front being the side closest to the ground)). Also any amount of wobble that comes from the act of dropping the item is going to have the same effect. Like how when you drop a single penny, it can stick to your fingers a bit. So once you drop a bullet (or any object really) it's going to start to wobble. Then after it's thrown off balance, it's going to try and reach balance again. Or I guess it's more accurate to say it's going to tumble until it's at an angle that stops it from tumbling. So a bullet is going from point down, to off balance, to tumbling. Where's it going to stop? At the angle that has the largest surface area of course. Because like I said before the back part of an object is experiencing less resistance than the front. So as long as the surface area of the back is greater than the surface area of the front, the force exerted on the back is going to be greater than the force exerted on the front which is going to throw it off balance (if that makes sense). And which angle of the bullet will give it the largest surface area in the front? The side of course. It's going to become as flat as possible to minimize the cross wind force. It's why raindrops become flat when falling. The rain at the "back" is experiencing less resistance so a smaller amount of force is necessary in order to move it from side to side. So it ends up moving from side to side until it falls on the "front" side of the raindrop at which point the force of the fall is the strongest force.
    Oh also weight plays a part in it too so that's how I think about it from a "this object weighs the same roughly all the way around" point of view. If one part of the object weighs more than the rest then that's going to fall faster, therefore dragging the rest of the object down (like in the hammer and feather experiment he showed). If you tied that feather to the handle of the hammer, it doesn't really matter what resistance the feather is experiencing because the heavy part of the hammer is going to drag it down. But if the surface area of the object tied to the back can create more resistance to balance out the hammer, then it's going to fall slower. Hence how parachutes work, right?
    Anyway the bullet thing just makes sense to me and that's how I explain it but I'm not a physicist or anything so let me know if that's wrong lol.

    *With my Physics Exam coming around, I'm gonna take the video name as an exam question. If you are just here for my answer, look at the bolded part.*
    When thinking about the physics behind dropping a penny from a tall height, it mainly centralises around gravity and its forces and energies - including air resistance, contact force, gravitational pull force, gravitational energy and kinetic energy. When dropping the penny, it's first going to experience a downward pulling force and an upward pulling force, which in this case, is air resistance, gravitational pull, kinetic energy and gravitational energy. With air resistance, the acceleration speed of the penny's fall will be slowed, but the drop will also be accompanied by gravitational energy, which is from the height, and also kinetic energy due to the person dropping the penny and the penny accelerating with speed and experiencing gravitational pull. After the drop, the coin will reach the ground, with contact force. It wouldn't potentially injure someone due to its small mass. Coming to a conclusion, it is *not dangerous* for a penny to be dropped *on a human* but will be dangerous if dropped on a small-sized object.

And thats not even taking into account the bigbangs hot temprature which shoulda vaporized anything. also there is too little antimatter in universe. if bigbang was real 99.999999999999999999999% of our universe should Not exist because antimatter destroys matter when it make contact with matter. the bang wouldve made much of it touch matter. so we see far less stars n stuff bc the so called bigbang wouldve destroyed nearly all of it. remember this comment if you truly wanna know if God is Real or not. read ALL of it, and hopefully know that JESUS CHRIST is the true God. screenshot it or keep this comment somewhere to read later. this should prove that Jesus is Real. JESUS CHRIST will Not make you take any mark, and He will punish the tyrannical ANTI Christ. The ANTI Christ will get a terrible wound, but cure himself to reinforce his deception to decieve the non-Christians and the lukewarm Christians. (look up lukewarm Christians on Christian websites and/or the Bible.) the AC will be world famous and very popular. he will make people take a mark on r hand or forhead. there will be a severe punishment for not taking it. The ANTI-Christ is a control freak, the opposite of Jesus Christ. Jesus uses His power for GOOD, NOT EVIL. This is BIBLE PROPHECY. Dont trust the false god, his goal is to get people into the lake of fire. he will go there too, despite all the FALSE MIRACLES HE WILL DO! Repent of your sins to Jesus Christ before its too late, you could die today!

    Maybe someone is staring up at the skyscraper at that very moment and it gets them in the face or in the eye.

      For that part of the video he was considering it free-falling, yes. In that case it's just a basic kinematic equation relating velocity to acceleration and displacement, v = sqrt(2ad). With an acceleration of -9.81 m/s^2 and a displacement of -443 m, that becomes v = sqrt(2 * -9.81 * -443) = 93.2 m/s, which is about 336 km/hr.

      Gravity doesn't affect the orientation of an object unless it's a very very big object (like the size of a large asteroid or bigger). The acceleration due to gravity is the same throughout the object regardless of mass or density (again, unless it's of celestial scale). What's not the same is air resistance. Conceptually, it would make sense for the thinner end to be oriented downward since it has the lowest ratio of air resistance to gravity and would tend to fall faster in an atmosphere. I'm not sure how that translates into the actual behavior.

Bump caps will provide some protection but hard hats are much more robust, not just because they are stronger but also because they have a suspension system in the space between the hard shell and your head.

      @Matt H bump caps are an actual thing. Its an insert that fits inside a normal baseball hat. Not quite a hard had but good enough for small objects and low overhead clearance

      @The CEO Actually a bump cap is not a hard hat, or at least not one you'd classically picture wearing on a construction site. It's more like a baseball cap with a hard plastic insert, sort of a halfway measure for when you're not expecting a brick to fall on your head.
      We use them in the UK in engineering environments, places where there are heavy machinery, engineers working at height etc. So full disclosure, I did not come up with it :)

    Pre 1982 pennies which are solid copper weigh over 3 grams when this was started so using cheap zinc pennies may not disprove this. Could change the terminal velocity of the penny.

    "That's around half as fast as a typical bullet"? Okay, come on now, that's stretching it. A "typical" bullet is almost always super-sonic, so we're looking at 330+ m/s, while 300 km/h is around 83 m/s. That's 4 times the difference/ Let's not forget that energy is proportional to the square of velocity, so suddenly we're looking at 16 times the difference in energy, and that's without air resistance. Kinda overselling the potential deadliness from the start

    A great demonstration of how much the media has changed in 20 years. This video tells roughly the same story as the Mythbusters episode, but it's a lot tighter. Great collaboration!

      ​@LiterallyCanadian there was way more science involved in this than in a regular Mythbusters episode. Mythbusters was, as usual with TV shows, mostly entertainment. A lot of focus on jokes or the interactions between the team members and ads. I can't stand any ads so I'm glad I can watch stuff like this now.

      Partly because in television you don't really have any control. Yeah you can change the channel but how many channels like Discovery can you find? Here, not only are there hundreds of other options, but you can open any one of their hundreds of videos if a particular one doesn't suit your liking

    Interesting Video, however, there are fundamental dynamics principles that would easily demonstrate the phenomenon shown in the video. The kinetics and kinematics of objects such as coin, pen and bullet should not be described as particle but rigid body, as dimensions cannot be neglected, therefore, rotational speed plays a critical role, not the velocity of center of gravity. This means, the drag is not a point load but a non uniform distributed load across the surface of the object making the object to rotate as it goes down, the difference in drag at different side of the coin/pen is responsible for reducing the rotational speed of the object and force the object to land on more stable horizontal position. The argument on the energy it takes to fracture the skull is inherently wrong, that depends on the size of the object and the material of the object, both the skull and the object are taking the energy, the one with higher modulus will take less of the deformation, therefore, the material it matters, the size of the object matters in the contact area which would be the basis for the resultant stresses. The 60 J is base don a standardized test, not any random object. It would be good to consult with an engineering professor before making videos. Good luck

    If you held the penny vertically and spun it dowards as you released it, it has the potential to hold its position and increase its velocity to a maximum as it free-falls. With this basic principle (mass/velocity/impact), Lincoln could easily split your wig!

    I used to work in the oilfield. As a floor hand. Our derrick hand had a zippo in his shirt pocket, and he bent over. It fell out, then it hit me in the hardhat, and left about a 2 inch dent. It knocked me down to my knees. I'm NOT joking. EDIT: Aw, hail! (sorry, it had to be said) Also, if you take a shopvac, and put a ping pong ball over its' exhaust, you can witness terminal velocity without a trillion dollar wind tunnel. Or, if you have floor vents in your home, you can place an inflated balloon over the vent, then watch it hover like magic.

    This is actually a relief for me. When I was young, I was on the 9th floor of an apartment building and I saw this woman lying in the amenities on a beach chair type thing. I dropped an ice cube and tried to aim for her. I missed, but I've felt guilty about that ever since. I don't know what I was thinking that day. Just one of those spur of the moment horrible ideas you regret as soon as you do it.

      When I was 10yrs old, my older brother and his buddies would be on the roof getting tans. My brother's friend would grab a handful of roof pebbles and randomly toss them over the side of our four story building. Occasionally, we'd hear someone yell "AAAAAYYYY!!"

      Hey @mike Cock, are you related to Mike Hunt at all? Maybe just best friends? I’ll bet Mike Hunt’s closest neighbor is an asshole.
      Amenities is a term for things like pools, gyms, and recreational areas that are all open to remember and guests at apartments and hotels.
      I agree that it is a strange and confusing term!
