To those discounting the dive speed as just gravity, I would point out that the terminal velocity of that cheetah falling off a cliff still wouldn't come close to the falcon's top speed.
Cheetah/Leopard dive speed cannot match with peregrine falcon because cheetah/leopard dont have drag reduction meanwhile peregrine falcon can reduce more drag by closing the wings and they have wing design to reduce drag and create more trust. Cheetah/leopard dont have that
@@a.jperez5684 tell the cheetah to use gravity too :) The falcon can use gravity while the cheetah uses friction. They maneuver throughout the air with a body optimized for extreme speeds like that. Obviously the cheetah can’t do the same so why is it not considered under the falcon’s own power?
@@somethchan1582 because the falcon doesn’t have to exert effort to use gravity. The cheetah needs to exert effort to use friction. No way the falcon is faster than the cheetah under its own power
@@a.jperez5684 lol what do you mean by own power? The ability to control the body while and after diving is counted as own power. Also there are birds flying faster than cheetah. FLY
Diving is the falcon using gravity to increase its own speed - the bird itself is not reaching that speed through its own movement. Cheetahs, on the other hand, reach their top speed through muscle movement alone. As such I would argue that Cheetah speed > Peregrine Falcon speed. If a _human_ goes sky diving they'll reach a pretty significant speed too, but you wouldn't consider a human one of the fastest animals, would you?
Vandergrif but falcons do this without the help of man made items to get them there unlike humans. Falcon do this naturally and are physically built for this unlike humans.
Humans are obviously the fastest animals on Earth, whose fastest speed clocked in at 24,791 mi/h (11 km/s) by the Apollo 10 crew upon atmospheric reentry. A little non-human bias, maybe?
"The world's fastest land animal relative to its size is Paratarsotomus macropalpis, a sesame-seed-sized mite native to southern California. Scientists recently clocked one traveling 322 body lengths per second, which, to scale, would be like a person running 1,300 miles per hour." So much for bias against insects.
Actually the smashing mantis shrimp could be another contender. They pack a punch as powerful as a .22 caliber rifle with acceleration of 10,400 g (102,000 m/s2). Against a solid object, they could punch propelling their body back a small distance, potentially much faster relative to their size than even the macropalpis.
aiden c- I think UndoRedo was saying the mantis shrimp could move a small distance upon pushing off a solid object with their fast arms, but we're talking centimeters or inches at best.
To people saying the falcon isn't the fastest animal in the world because it uses gravity to go fast: Peregrine falcon horizontal speed- 71mph Cheetah land speed- 62mph
A little disappointing the video didn't mention horizonal air speed. Some birds, such as the Spine Tailed Swift can reach horizontal speeds of over 100 mph (160 kph), which blows the cheetah out of the water.
bbgoodnough all fast animals use the enviorment to their advantage in some way why does the pergerine get put out just because it's using gravity doesn't change the fact that it goes 3 times faster than any other
please cite your sources. I'll have you know Cheetahs go 0-60 in 3 seconds flat. Also let me know how long it'll take a falcon to go from 0-60mph. Thanks
Except being on earth means being in earths gravity. Or else you wouldn't be on earth if you jumped? Or what if you dive under water, would that mean you werent on earth either because you werent standing on solid ground? You'd still be on earth
The comparison between an animal that dives and one that runs along the ground is a bit unfair. A human can travel around 120mph when diving from a plane, doesn't mean we're faster than a cheetah.
Lee Nesbitt i guess i agree but it's also a function of the bird. the bird has been made to dive that fast, which is incomparable with a human in a plane because that's the plane's function, not ours. idk just some perspective
"Fastest speed possible by an animal *without the use of external-to-the-body apparatus*" Since humans and any other animals aboard planes/spaceships can travel faster than the peregrine falcon....
omar hassan no this is Max speed whether you like it or not the peregrine has gone over 200mph doesn't matter if it used it's enviorment to help all fast animals do in some way
They are the fastest. Thats it. I've seen some comparisons in the comment section that are very moronic "if a cheetah falls downs a cliff". That is not a valid comparison. We are talking about a animal that uses gravity and aerodynamics as a means to achieve speed. Also, saying that we should consider humans cause we can use plane, its not valid, cause planes are built, ergo, they we are not fast, its the plane. Or when a plane is going at the speed of sound we say " that human is going at the speed of sound" or "the plane is going at the speed of sound"?
The falcon flies very high and then dives in order to get those speeds. A cheetah can be sitting doing nothing and next thing you know it's gone, it doesn't need any special condition in order to accelerate very fast and run fast. That's the difference.
But a cheetah can't physically reach the same speeds as the falcon, and for not as long either. Even if the cheetah could somehow reach it, it would not be long for this world since it is not built to be like that. Also, cheetahs can't run at their high speeds for very long at all, they *need* to cool
Friction is a constantly resistive force. Gravity isn't. The falcon literally doesn't exert any force when falling therefore the speed isn't the falcon's achievement. Just like a person sitting on a plane isn't putting in energy to be traveling at such a high speed. Cheetahs are the fastest, all of their movement comes from their own energy.
This bird is called Hayabusa in Japanese. The fastest production bike (Suzuki Hayabusa) was named after this bird.. I once had a Hayabusa (the bird ofcource, as a pet)..
Why would you measure the speed of the falcon while diving, not while flying straight. Wouldn't the equivalent thing with the cheetah be that you throw it down from a cliff and measure it's speed?
But the bird is made to fly at high speeds and that's how the bird gets its prey. Technically if you throw anything from a cliff it could reach high speeds but would serve no purpose
I love how at 3-4 secs into the video the Google search she shows clearly states in the caption of the first 'actual' search result, "The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom with a dive speed of 389km/h (242 mph)." **Sigh** a whole video based on perceived bias due to a lack of reading! Irony anyone? Also, that photo result scroller in titled "Popular on the Web," not "This is the definitive ordered list for your search." Oi. Reading ftw.
1:00: "This streamlined figure reduces wind turbulence, maximizes maneuverability, lift, and speed...". It *minimizes* lift. It's wings generate lift, so when it tucks them in, it's no longer generating as much lift. Lift causes drag (this is caused induced drag, pressure drag, or simply lift due to drag), so if the Peregrine wants to maximize speed, it needs to minimize lift (and thus, drag).
This is the interesting find in the internet, peregrine falcon, (Falco peregrinus), the most widely distributed species of bird of prey, with breeding populations on every continent except Antarctica and many oceanic islands. Sixteen subspecies are recognized. The peregrine falcon is best known for its diving speed during flight-which can reach more than 300 km (186 miles) per hour-making it not only the world’s fastest bird but also the world’s fastest animal.
The Cheetah is the fastest animal when on land, using physical movement. The peregrine is fastest in air which doesn't necessarily need muscles, it's more about aerodynamics. They're two different classes of animal speed and you need to be more specific.
Actually the cheetah IS the fastest animal alive,the peregrine falcon is only DIVING.If humans were to dive HEAD ON against the earth with wings that can make them go against their terminal velocity them we ourselves could go to that speed. Plus they are going with gravity and have a lot of potential energy.
Jason Park humans can't reach 200 mph in a free fall. The only animal that can in the peregrine. Try dropping a cat, dog, hell try a blue wale. You will never reach the efficiency and aerodynamic properties of this bird.
Yes we can,It all comes down to size density potential energy and other factors such as wings and how you position yourself against the gravity and air resistance
You're dumb AF. Might as well put a human in a fighter jet in your scenario. Peregrines are still the fastest. No one said they couldn't dive. Every animal uses gravity, idiot. Cheetahs use gravity in their stride to push against the earth.
you stupid.Peregrines are using the force of gravity WITH THEM for potential energy.Like you said cheetas use gravity against them having to push themselves against the floor while peregrines just have to face downwards
Another interesting find, no animal on earth can run faster. But a peregrine falcon can swoop faster than a cheetah can run. And the falcon can compare to an airplane, a rocket, or the speed of light.
To all the people saying the comparison is unfair because humans can skydive: The falcon uses its own evergy and muscle movement to reach altitudes that allow it to steep dive at these high speeds. A human skydiving does not. That would be equivalent of climbing a high mountain top and then jumping off, trying to reach 200 mph - that's right, the cheetah dies while the falcon pull 25 Gs.
What about it is not well crafted? I'm pretty sure it's just trump supporters brigading every vox video because they apparently don't like hearing facts.
They forgot to include horizontal velocity and only included stooping making many commenters think that it's cheating because it's just falling while the cheetah has to actually push itself forward. Their "explanation" for the question in the title is basically "because aerodynamics". The whole video was far less informative than a typical Vox video and was more at par with Buzzfeed.
your writing have some merit, but abit biased... faster animal Google result is based on most webpage actually say fastest land animal, your 2 keywords are poorly choosen. that peregrine doesn't achieve such high-speed by accelerating by muscle force... they use gravity assist. I do admit it is impressive how their physiology adapts to survive such fall and gforce, taking advantage of gravity. but cheeta it way more impressive in a engineer stand point, being anatomy so efficient in weight to power ratio...
twitte0king precisely, it's just such a shame when vox makes such an interesting video but ruins it by having such a careless intro. Really takes me out of it.
twitte0king You're using a human bias by saying "well... Cheetahs are cooler" as a basis for determining which is faster. Falcons have features that let them handle such air forces, which is all that matters.
Flynn Gumshoe there is no bias involved... I am pinpointing on her Google search about "fastest animal" the objective fact is that there are more website about "fastest land animal" than "fastest animal". that's why her keyword search yield site that are actually about fastest land animal... also, comet are extraordinary that they travel thru space in long journey and crash on earth crust in crazy high speed! but comets doesn't have any propulsion system that initiated that thrust/manuvalbility, gravity did most of the work. when spaceship and rocket are far more interesting and cooler in terms of propulsion and engineering, like cheetahs, the muscles has to be efficient, any extra gram is dead weight, still they have to pack fuel, the glucose in their muscle has to support all their sudden acceleration without getting too much into anaerobic reaction (which induce muscle strain)... the peregrine is very interesting too, but her way of drawing interest in the begining of film is logically a bit misleading... especially for youngsters who are developing critical thinking.
Why are some people trying to make this more difficult than it actually is? Falcons are the fastest animals (yes faster than humans) solely based on natural ability; without help from technology. With technology any animal can be faster; just strap it into a rocket.
while I was in socal last year, I saw a pigeon disappear right above me. I think my exact reaction was "dear god what happened" perhaps it was a peregrine falcon, since it was this blur of feathers and then blue skies
Saying the falcon using gravity means it should be disqualified is an extremely basic way of thinking. You don't have a point of reference for what it's like to move that quickly with control of you movements in a 3D space. Besides falling is part of all locomotion on the planet including running. A cheetah moves the way it does partially because of the way it moves during its flight through the air. Anyone that's run track knows it doesnt become any less technical when both feet are airborne. If you want you can think of a falcons climb and dive as a single bound. It's able to achieve these speeds because of its efforts the way a cheetah never could. Plus the falcon rivals the speed of the cheetah even when it's not diving so there's that.
Carl Simmons Ok cut the falcon's wings and put it on the floor next to a cheeta and make them race (Somehow)... Obviously the cheetah would win because the falcon did not evolve to use its legs to gain speed. Now throw both a falcon and a cheetah out of an airplane and see who can fly faster. Nonsense again because the cheetah did not evolve to fly now did it. Cheetahs run. Falcons fly. Stop comparing everything you see. Is like trying to tell which pepper is more spicy than another... You cannot compare a habanero with a ghost pepper because even though they both cause pain they do so in different ways that may be taken by the body differently.
Ok, so I googled "fastest animal" and i got the same results as shown on the video: the first page is a Wikipedia article stating that the peregrine falcon is the fastest bird (and also the fastest member of the animal kingdom), the cheetah is the fastest land animal and the black marlin is the fastest sea animal; the second page is a top 10 stating again that the fastest animal is the peregrine falcon. There was no images, but I guess this can vary. My point is that there is no bias for the cheetah and the intro is just a lie to make things more interesting, typical of journalists..
Thank you Thank you Thank you, for covering my favorite bird-of-prey (well, owls too) suncemy Teens. They began using them in airports to hunt pigeons so they didn't get sucked into airliner turbines and lose a flight. they've thrived in cities ever since
Despite being an avid birder and living in the area with the highest density of them in the world, I still have not seen one of these marvellous bastards.
From a balanced mass to speed aspect, a couple of insects could go faster than any other animal. (You know, if it'd be the size of a dog or something.)
doesn't count because it isn't under its own power. It's just falling, and gravity is doing all of the work, while the falcon just stays aerodynamic. Still cool how it can go 200 mph, but it's not like a cheetah, where it is powering itself for the short amount of time that it is at 60 mph.
At horizontal flight the Brazilian free-tailed bat is the fastest flying creature on earth, these bats are faster than any other birds and reach speeds of over 100mph
There's been some newly found research from a 2 or 3 years ago that found out that a bat, specifically the Tadarida brasiliensis may be able to fly at 100 or 160 mph. Although they're still researching on specificity if there were any other things adding to their flying speed, like diving. It's really fascinating you should search it up!!👍👍
Hey, genius the peregrines are the fastest animals out there but it's only when there diving, that's like you comparing Usain Bolt to Felix Baumgartner
I see these falcons often where I live. I saw a video once from a local animal reserve that said that these falcons can actually dive faster than 250 mph, but the equipment they clock them with can't read speeds higher than 250 mph.
Maybe, maybe not. But as I and many other viewers appear to feel, it seems cheap to use such a 'click-bait' title and intro which requires the omission of certain qualifiers such as "the fastest animal in terms of raw speed" i.e. not in terms of distance relative to body size (see Paratarsotomus macropalpis) and allowing for the influence of external, non-reactive forces such as gravity.
"clickbait"? I clicked because I'm interested in animals and science in general. If you were "lured" by a rather mediocre title that's on you, not them. Secondly, the peregrine falcon IS the fastest bird AND the fastest member of the animal kingdom, as this article clarifies: www.airspacemag.com/flight-today/falling-with-the-falcon-7491768/ "omission of certain qualifiers," now that's laughable. Do you want them to make a documentary just to please you? And quit the bullsh*t of "external, non-reactive forces," the falcon has EVOLVED to take advantage of its environment and to reach that speed, just as cheetahs have evolved aerodynamic skeletal frames, including tails as a means of steering to help them make sharp turns (oh look! Cheetahs taking advantage of momentum, velocity, and gravity!). Idiot.
If we are allowed to factor gravity into the equation(as with the Peregrine), humans are the fastest animal. Felix Baumgartner hit a top speed of 843.6 mph!
PerefL gravity is an external tool the environment is an external tool too. Everybody says humans are better than animals because we evolved our greatest assets our brain. So to disqualify us for using our brain is pointless. Anyways people pick and choose when something applies to us
Actually my most watched video is an Anaconda cover, but I reuploaded it and it has like 5 views now. It had like 1.3k before. My cheese video is pretty great, but I couldn't stop laughing while making it. My personal favorite series is the apocalypse videos and i am posting the third as soon as I get 100 subs or before then if I run out of videos. I hope you enjoy my videos though. That is the most important thing.
A huge misunderstanding of aerodynamics here....the shape the falcon is in while diving doesn't improve manoeuvrability, it has to splay its wings to turn....and the cone on a passenger jet as shown has nothing to do with slowing down the air, its only in supersonic aircraft where that sort of cone is used.....I like your videos Vox, but please make sure you understand what you are talking about.
1:09 'This streamlined figure reduces wind turbulence, maximises maneuverability, lift, and speed as it cuts through the air' This is very wrong. The streamlining does reduce turbulence and increase the speed, but it does the opposite to maneuverability and lift. The bird is far less maneuverable than normal since it has lost most of its control surfaces. It isn't maximising lift since that would defeat the whole point of what its doing. It's Diving. The bird wants to produce as little lift as possible to reduce drag and increase speed. Whoever wrote that line either needs a better proofreader, or nobody involved actually has a clue about the most basic of aerodynamic principles
the presenter is crazy. Google fastest animal and you get: 1. Peregrine Falcon Peregrine Falcon (Wikimedia) Frigate Bird (Wikimedia) Sail Fish (Wikimedia) Cheetah (Wikimedia) Disliked
I get: Cheetah 1. Peregrine Falcon Peregrine Falcon (Wikimedia) Anyway, Google results are different based on your browsing patterns, your demographics, geography etc. so you cant be sure what comes up when someone else searches for something
People need to learn to google search properly. Theres a difference between "fastest on earth" than "fastest in air" and theres also just plain "fastest in existence". Thats y theres a lot of retarded comments about ppl getting different results. Smh
There are a ton of comments complaining that the peregrine falcon uses gravity and that makes this comparison invalid. It doesn't (not even discussing all the techniques that the bird naturally possesses to take advantage of ever present factors). This is simply one of several comparisons of different records held. Cheetah: fastest *land* animal at up to 65 mph Black Marlin: fastest *sea* animal at up to 80 mph Brazilian Free-Tailed Bat: fastest horizontal speed at up to 100 mph relative to the ground White Throated Needletail (bird): fasted _reported_ but not recorded horizontal speed at up to 105 mph Peregrine Falcon: fastest speed obtained by an animal at up to 242 mph recorded speed
Peregrine Falcons apparently don't usually claw their pray like most Birds of Pray, they instead make a fist with their talons and bash their pray. Yes a Falcon Punch is a real thing.
The reaction to the cheetah was a bit...idk stupid? Google is focusing on land animals because a peregrine falcon can use gravity to its advantage while a cheetah is a physical specimen.
Nick Jones, A cheetah uses the ground to propel itself forward, while the peregrine falcon uses its body to guide the wind around it. Pretty much the same thing.
I see what you mean, but gravity will pull you down no matter what (unless you have an equal or higher force pulling you up) while the ground requires you to put in most of the effort, unless you wish to just sit there.
What next a video on how Superman is faster, than the flash? I appreciate the information, but there is a difference. One uses a dive technique and the other using all its muscle energy for a short run.
INCORRECT! With this childish logic you'd have to drop the cat off of a cliff, then you'd only discover that the bird can fall faster. It *cannot* travel faster. Peregrine Falcon straight line speed is 40-60mph. Cheetah straight line speed is 68-75mph. Look it up.
philonetic that's a valid point... falcon uses gravity and aerodynamics to gain speed to catch it's pray... but cheetah builds it's own speed in 3sec and maintaince for 20 to 30 sec...
I see everyone arguing that cheetahs are still the fastest because they don't use gravity like the bird does, and it is hard to compare a bird to a cheetah but maybe to not trigger people they should say it's the animal that can reach the highest speed without the use of technology. Not saying it's the fastest but it can reach the highest speed
