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!

When hiking in Costa Rica we found a waterfall that had a little nook behind the water. The way water was pushing the air up in the nook was exactly the right force to make the water float. So you'd lean back into that nook and watch these floating droplets swirling before you. It was totally out of this world

@Splintered Space it was not a tourist place at that time. But it was know among permaculture farm communities. Its very close to a farm called Finca Amrita They used to have ayahuasca ceremonies in the massive cave behind the waterfall Granted, this was 10 years ago. I haven't been there since, but the farms should still be there. If you look for groups offering ayahuasca in that area, they will certainly know the waterfall
As a Physics undergrad, this video scared me because for the first time, we saw that air resistance isn't negligible.
OMG you are a good person and I 🤞👌🙀👌

If you are an engineer, air resistance becomes a pain unless you can assume it to be constant in certain cases
@Mayank Bisht I stay light years away from engineering, so I barely have a clue. Every time I see the mention of air resistance, I happily ignore it. Both experimental and theoretical Physics is great, but engineering goes right above my head!😅

Could you "stabilize" the penny's rotation by spinning it with the edge (like rolling a penny across the table, but down a skyscraper)? That would minimize the surface area and increase terminal velocity
Govardan 8 ヶ月 前
Albatboss E
Albatboss E 6 ヶ月 前
The barrel of a gun is "rifled" to spin the bullet which does what youre saying. Get a good spin on it and it should continue cutting thru the air until it runs out of spin juice
Robodude 6 ヶ月 前
@Albatboss E that's what I was thinking too, rifling stabilization. I'm just wondering if there'll be a Magnus effect on it, adding a horizontal component to the velocity and potentially affecting terminal velocity. It's probably also going to depend on how much you spin it, which makes it harder to test
jazzochannel 5 ヶ月 前
Just rolling would not be enough. You'd have to spin it up to 6000 or more RPM imho. Bullets leave a gun spinning at more the 100,000 RPM.
Hidden 2 ヶ月 前
the stabalization of a rifled barrel has no effect on its terminal velocity. it isn't cutting through air, more than it is equalizing the air-resistance across its surface, so that it doesn't stray or shift in the air and lose accuracy. Dropping a penny facing perfectly sideways, will have a faster or equivilant terminal velocity than trying to spin it... And spinning it is more likely to throw it out of alignment of being perfectly sideways, because it doesn't work the same way a bullet would. A bullet is cone-shaped. A penny is not. The sides of the penny being vastly wider than the edge, would already naturally keep it sideways, IF dropped perfectly sideways... That said, even something as small as the engravings on the sides of the coins could throw it off, and it may be impossible to get one to perfectly drop sideways, and once it enters a vertical spin, it will maintain that like a windmill.

Amazing video and I love the colab. I'm a big fan of Mythbusters. I think that in 17:50 there's a little mistake. Drag force also affects a bullet in its horizontal motion so its speed will not be the same one that it has when it was fired (don't get me wrong, it's still lethal, but not like a direct shot). Also the bullets fired by a gun have a lot of spin, so by the Conservation of Angular Momentum they tend to maintain their orientation much longer.

One question I've always had is that if you were to roll the penny off a ramp so that it imparted a vertical spin to it, how much would the coefficient of drag be reduced were it to be falling vertically? How much more damage could it inflict if it were dropped in that manner?
Sarah Rose Stiles
After a tumultuous windstorm in Michigan this summer, in the backyard I found an 8-10-inch shard from a tree branch that had stabbed into the ground, still standing nearly straight up. I guess probably wouldn't normally happen in a free fall, and perhaps wind power, and the elasticity of the tree branches whipping around acted like a sling shot, playing a role in catalyzing this occurrence.

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 my college physics text book in the chapter on terminal velocity there was a cartoon image of a skydiver falling next to a mouse with no parachute. Because the mouse has so little mass it's terminal velocity would be so slow it not only would survive the impact with the ground but it would most likely walk away unscathed. Now there's an experiment I'd like to see these guys do.

During my secondary schooling, I attended a science exhibition at a university. This video reminded me the challenge I was given then. The challenge is to put a coin into a small tumbler placed at the centre bottom of a bucket filled with water. Probably it is interesting to try that out in your coming up videos. Did you guess the answer? For the first try I freely left the coin at the centre of the water surface. It pushed the coin to edge of bucket. For the the second, I spinned it from a random position into the water. There you go it did the magic. Now that I studied physics it seems simple, but then it gave a great pleasure. Unfortunately, I wasn't given the promised prize i.e. a chocolate as I put only 2/3 tries.

In my opinion, I also think the danger of it really depends on how it lands on a person. If it was dropped from the Empire State Building and lands on its flat surface, then yes, it wouldn't be dangerous. However, if it lands on its ridges (skinny sides), then it could slice through the skin, probably even the brain if it lands on the head.

As you can likely guess, the show cuts to Adam and Jamie going up the Empire State Building with a handful of cats. The rest is pretty indescribable, but we think you can imagine it does not end well for the cats. From what we can tell, no one actually made it to the end of the episode, everyone left the theater to get sick in the hallway rather than continue to watch. When Discovery got wind of this, they immediately halted production of the show and would soon cancel it permanently, claiming the show had ‘run its course.’ Unfortunately, we now know the terrible truth.

As a skydiver I have jumped in the rain and it hurts as you fall onto the rain. People used to joke it was because the cartoon raindrop was pointy at the top. The reality is, you're falling at 200kph and the rain is 20kph so the rain is hitting you at 180kph!

I'd be much more worried about that bucket full of pennies held so casually up there - I didnt think that was the safest demonstration
It would be curious to discover what the Snopes web site has to indicate concerning this issue. Back in the day it was suggested that if you dropped a dime off of the Empire State Building it would sink ten inches in the pavement below. In Omaha, Nebraska it was suggested the if you dropped a dime off of the old Woodman Tower, 9 times out of 10 it would hit a lawyer.

I think the biggest actual danger in this scenario would clearly be someone dropping their phone off the Empire State Building lol. I'm assuming that is heavy enough to actually injure you, rather than a pen or penny.

40-60 joules or so, I'd guess. Hard to know its drag coefficient and all that fluttering. Just under enough to crack a skull, but if unlucky and all that force hits you with the corner of the phone, then enough force on the point to do serious damage.

Dropping a payphone off the Empire State Building would most definitely hurt someone assuming that the covariance properties remained unchanged throughout it's journey to the sidewalk below. Especially if this profound event happened during a warm month like July when the air is less dense.

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.

To better understand ballistics you really need to look at the importance of rifling in the barrel that proves the stabilizing ‘spin’. The spin put upon bullets can be quite extreme. I was shot at once in a K-Mart store, the .223 bullet ran out of forward energy as it had gone through the store window and isles of merchandise, it dropped onto the floor in front of me…still spinning ! Those .223 rounds spin around 100K rpm I believe.

*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.

I’ve noticed a couple of holes (pun) or misconceptions in the experiment. I see the horizontal (flat) and flipping differences in terminal velocity. But I didn’t see a demonstration of a spinning penny, which would have an entirely different terminal velocity due to a gyro effect keeping it from flipping [until it slowed], allowing it to STAY on its edge. Also, I don’t imagine a bullet arrives at peak altitude and flips over and continues to tumble. I expect it reaches the “top”, begins to fall until the spin slows enough that it can. I’m curious, if a bullet was to be designed to be pointed on both ends, could the spin last long enough to keep it vertical?

What if you drop a very long arrow (so it's more aerodynamic/stays straight) about the weight of a penny (or a little more) from the height of a building? You can ever put most of the weight at the end/tip. Though I think he answered this by talking about those war weapons.

I would think it would be similar to being shot with a BB gun but far less injurious due to the wider area of the penny and its flipping that should also cause some drag as opposed to a similarly shaped and weighted object made to be heavier on one side so as to cause it to slice through the air. BB’s shot from even a low powered Daisy Red Ryder can imbed in the skin or “ put your eye out” if not wearing shooting glasses. I expected to see the use of body protection or ballistic gel padding to show any penetration.

Jesus Christ died for our sins, rose from the dead, and gives salvation to everyone who has faith in him. True faith in Jesus will have you bear good fruit and *drastically* change for the better! Those led by the Holy Spirit do not abide in wickedness. *God is ONE manifesting himself as THREE;* the Father, the Son, and the Holy Spirit! Bless him! *For these three are one.* As I am led by the Holy Spirit, nothing I state is a lie, but the truth of God. Anyone who tells you differently is misinformed or a liar. They do not know God, nor led by him. Anyone who *claims* to be a Christian and is against what I am doing, and where I am doing it; the Holy Spirit does not dwell within them, they lack understanding. They know not God, read his word, and their religion is in vain. Do not hear them, they will mislead you, the lost cannot guide the lost.
YAHUsha 年 前
When you trust in God and cast your cares (worries, anxiety, depression, suicidal thoughts) upon him, they will be NO MORE! Know that there is power in the name Jesus Christ! His name casts out demons and heals! The world is wicked, evil, and of the devil. I too, was a wicked sinner of the world before I opened my heart to God. I am living proof of God's work and fruitfulness! He is an active God who hears the prayers of his! God's children are set apart (holy) and righteous. The devil is a liar that comes to steal, to kill, and to destroy; that includes your relationship with God.

Occasionally, a restaurant will have a charity game where you drop coins into a tank of water and win a free shrimp or something if the coin falls into a small glass at the bottom of the water tank (aquarium sized). My children learned to game the game by dropping a stack of coins together - this assemblage of coins would stay together and take randomness out of the trajectory and the coins fell pretty straight thru water. I wonder if the coins being dropped in a cylindrical stack oriented vertically would be more dangerous due to a presumably higher terminal velocity?

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!
