One of the most common physics misconceptions is that an unbalanced force causes constant motion. In truth, an unbalanced force leads to changes in motion - accelerations.
+John Doe Which part of D-K? Certainly you don't mean the 11 yr old at the end over estimating his ability... You must mean Derek thinking Newton is easy... Right?

Kudos to you. I did it for 12 years and went back to engineering. As a teacher I had no life, it was grading papers all weekend long, every weekend. Plus I make twice as much now.
>I teach high school physics I seriously hope that's a lie. Veritasium is COMPLETELY WRONG, alright? The Earth continues to spin because of gravitational force. When you look at a chunk of the Earth, if there were no gravitational force, it would continue flying straight and would move away from the Earth. Have you ever tried spinning a wet ball? That's what would happen to the Earth. However, if you had some centripetal force (in the case of the Earth, gravitational force), the ball would continue to spin, and the ball would stay a ball. The granite structure there continues to spin because chemical bonds provide the centripetal force. He literally says the Earth continues to spin (i.e. not "maintain its state of motion") because of inertia. This is not something I would expect even from kids in middle school.
The older 'student' had learned to fear giving a wrong answer and therefore could not state the correct answer. The younger 'student' had not yet learned that fear and simply said what he thought to be correct.
I doubt they are true physics students, I'm sure they just are enrolled in the class and never showed up. No one who was in physics, even in HS physics wouldn't know that it was acceleration or inertia.
+Bruce Howlett The vast majority of people took physics in high school, and the vast majority of people would not know the answer. There is a flaw in your statement. I don't understand the reasoning behind ridiculing those that don't know the answer.

I guess you don't consider it a possibility that you are more educated than the average person.

It's like if I claimed to be a history student and couldn't tell you when WW2 happened then that would be pretty sad. In my high school everyone was pretty educated. I value my education a lot because I WORKED for it. I would say I am more educated than the majority because I worked my ass of studying to get into a good college and get a research fellowship.

The way you did this, with any confrontation, or embarrassment, you were able to educate them in a way they won’t quickly forget. The way that you led them, they way you engaged even the younger children was awesome. I think what impacted me the most as a teacher, is that you did this, especially with young minds, in a way that only boosted their self confidence and faith in themselves!

That kid is impressive, he wasn't randomly shouting out words he thinks are associated with the topic hoping one will eventually be correct ("carpet bombing") like a lot of the adults were, he was actually thinking. That's a rarity these days. Sadly he has no confidence...
***** As far I know yes. My college lecturer for chemistry said it. It's where a student shouts out anything and everything hoping one of the answers will be correct. It's hated in college because the student in not thinking about the question and trying to understand what's being asked.
Carpet bombing, a fitting term! I would say that type of semi random answering could likely be the result from our education system's focus on the getting the "right answer," and a reflection relentlessly teaching to the test. Which totally misses the wisdom in the process of learning through attentive observation and experimentation. In essence, that's learning backwards. Learning theory prior to observed reality skips the vital process of nurturing a sense of curiosity, awareness, and creative problem solving by connecting concepts in new ways, without being afraid of "getting the wrong answer." I'm glad this kid has the beginnings of this kind of curiosity of how things work, we all need more of that. :)
I think he's Japanese--in Japanese a consonant is always follow by a vowel (except N), so Japanese people typically have trouble not saying a vowel after a consonant. Hence why he tried to say 'So strange' but instead added a vowel after the 'g' sound to make 'strangey.'
He probably just changed that boy's life with his encouraging and flattering to him! That kid will maybe grow to be a next generation genius! All we need is a little faith in us to make us grow!
Idk man. Basically everyone in my class knew that. We were in 7 grade at 11 and everyone had learned that already. You learn plenty of basic physics in middle school
I'm a bit late but ... Children are creative genius. Our school system destroys the creative capability in nearly all of us. you can check TEDx talk about it: ruclips.net/video/ZfKMq-rYtnc/видео.html
I honestly was really impressed by the kid. Although he didn't necessarily have all of the proper terminology (angular acceleration, torque, and angular speed), he still understood the concept of inertia far better than any of the other people interviewed. That kid is going somewhere in life.
bruh he kinda had proper terminilogy, he said force causes change in speed. if just instead of speed he told velocity that would be full proper definition.
Smart people aren't the ones who memorize everything on school and get good grades. Smart people are like that 11 yr old kid, who learns by himself and discovers the world by his own observations. That's how cience evolves, with new observations of people who think by themselves, not by doing Pitagora's algorithm.
***** Reminded me of my autistic niece. Briljant girl in her own way. Badly judged on things that doesn't matter. She's gonna be a great programmer one day. :)
Jay Theriver I think it's great when the public is interested in science, but if you want to understand really fundamental, cutting-edge physics then you actually do need several years of education.
That last youngster has more knowledge of physics in his little finger than all the other interviewees combined. Well done, lad, I predict you'll go far!
I officially LOVE how you speak to the kid at the end Especially when you asked do people say you're smart? I think you're smart. Great work man. We need more people like you on this planet.
I wonder if younger people have an advantage because they don't think they know as much and because they are still in the stage where they are observing and learning. As you get older you are hampered by the illusion you already understand your world.
i think thats caused by the way you grew up and learned/studied by reading things other people wrote/discovered, rather than learning trough your own thoughts/discoveries
I used to think British accents were cool, but then I heard this guy... 0:48 "Soooooaw strenngiee" That guy officially has my new favorite accent *of all time*
+KitMellow I currently live in UK (I'm not british) and all I can tell that british accents are not as cool as people think they are. Some of them (yes, there are loads of different british accents) sound decent, but they're ugly and hard to understand most of the time
The 11 year old was able to answer very easily because he’s not over thinking. He’s mind is free to observe things without pressure or shame of delivering the wrong answer. The older we get, the more rules we put on our thoughts and we lose the ability to think freely like a child. Give the child a few more years and place him in front a camera and he will more than likely produce the same response as the older kids just because of how the brain functions. This is why a kids are scientists in a way by nature. By having the ability to maintain that curiosity into adulthood, can produce some of the best scientists we know to today.
Just hearing "change in speed" made me sigh with relief. How can someone who even took a physics course not know about inertia and mass's tendency to resist change in motion?
4:40 if this kids parents are watching this...we need kids like him!! Hope you guys will understand his capabilities and show guide him to the correct path in the coming future!! :D
I think at the end Derek should have told the kid about Newton. "Have you heard of a guy called Newton? What about his 3 laws of motion? What you just came up with was the first 2 thirds of newtons laws of motion." really inspiring.
Funny enough that 11 year old boy was the only one that got that the ball was accelerating when force was applied.. tho he didn't have the vocabulare to explain it.
lol im surprised absolutely everyone didnt say something that simple. I would have made it even simpler and said. Newton's laws of motion. Pretty much sums it up
Lmao it's so simple yet as grown ups we often overthink things. The kid nailed it. I remember a test that was popular when i was a teen. Idk if it was made by Mensa or whatever but I vaguely remember the final results of the test. Something like 85% of all children answered correctly while 75% of adults when asked the same questions were incorrect. Simply from overthinking and making the problem harder themselves.
2:32 kid without formal knowledge gave correct answers everytime, just without using technical words And everyone else, adult gave answer gravity, speed velocity It's amazing
***** He didn't try to make anyone feeling bad imo, it is something you assume. It is simply something that is obvious to me (and I assume him too) so it suprises you when there is someone that doesn't know. It is how people work, they take their own knowledge for granted.
Sabaca That only works so long as you remain oblivious to the concept that everyone knows different things. Once you recognize this, being blown away by someone's ignorance is silly.
Damn that kid did great. He pretty much came up with the Newton's 2nd law on his own. It was 9 year ago, I hope that he stayed sharp and is doing well in life today.
That kid did seem pretty smart, It was obvious the flattery was making him uncomfortable though lol. Perhaps a better approach would have been to have given him a physics book or Euclid's the elements... Basically Veritasium should try carrying around some books with him to give to the smartest kids he meets, who knows it might one day change the world.
The kids just amaze me in how they are just observing and telling what's happening .. I guess scientists are just kids preserving their observation powers growing up 😄
I think the answer to this like force changes speed was known to those adults also but they are pre conditioned to be hesitant to answer thinking it'll be embarrassing if they were wrong, and the kids just let out there curiosity without thinking about any judgement from others and they were right, so the conclusion can be that being afraid of being judged can become an obstacle for your own learning
"two and a half tons of Inertia" - that's not the unit to use in this case. What matters is the moment of inertia, and that has units of kg m^2. It's not just the mass, but also how it's distributed about the axis of rotation. A little bit of calculation, and taking the density of granite as 2,700 kg/m^3, and the moment of inertia of a solid granite sphere of mass 2.5 metric tons is 360 kg m^2.
When you go buy an Air-Conditioner. You say 1.5 Ton AC... Here 1.5 Ton stands for 1500 Watt. Means 'Ton' is used as 1000 in common vocabulary. So when he said 2.5 Tons of Inertia he said 2500 units of Inertia. The unit generally translate to the convenient unit. In USA they use Imperial units, in commonwealth countries they use SI.
@@HiQuantumSKY As it is, Americans do not use Imperial Units, they use US Customary Units, which are based on an older English system of units. Imperial units were defined by the Weights and Measures Act 1824. As the USA became independent in 1776, they never adopted them. Hence an Imperial ton at 2,240 pound (known as a long ton in shipping circles) is about 10% more massive than a US ton (known as a short ton) at 2,000 pounds. As it is, the Imperial ton is quite close to that of the metric ton (1,000 kg) being equal to 1,016.05 kg whilst the US ton is equal to 907.185 kg In any event, none of this has the slightest to do with the difference between using mass as a unit of inertial for rotational, which was what my comment was about. For your information, the unit that would used for the moment of inertia using Customary American Units would be pound-feet^2. However, the universal standard in physics is to use SI units (and that includes in the USA; physicists there use SI units, just like those in the rest of the world). That tons of air per hour is used on AC unit specifications in the USA has precisely nothing to do with this.
@@TheEulerID I understand your point. And I know that mass alone cannot stand for moment of inertia. The size and mass distribution also important. But when you are talking about a homogeneous sphere you can tell only mass as comparing factor for inertia. He just used 'Ton' in unprofessional way. And everyone gets that. That was my point. And all you said about units and where they come from doesn't matter to our conversation. By the way I'm also a physicist. I well understand difference between the both inertial quantities. The thing is in India we do use SI units. We know that other units are there but we don't bother about there values accept what British gave us before our independence. .
@@TheEulerID It is same in a way that when someone ask you your weight you dont tell them weight instead you say mass. So that was the catch to use Ton.
@@HiQuantumSKY That's completely irrelevant to the difference between inertia and the moment of inertia. It's like describing the speed of a flywheel in metres per second rather than radians per second.
"You seem pretty smart for an 11-year-old. Have people told you you're smart?" "No" "Do you think you're smart" "No" "I think you're smart. Will you take my word for it?" "Ok" - Proof of failure of public education and commonly-held misconceptions of human intelligence in action right there! (See some talks by Sir Ken Robinson :) )
your most recent video about synchronization discussed moons spinning around planets and showed you playing with your kids, then this video was recommended to me, in which you discuss rotating planets and you talk to kids. heartwarming!!!
one day when that kid grows up to be a great person or a scientist... someone asks what inspired you ? he is straight gonna say when i was 11 one person said to me he thinks i am smart.. and i took that to heart..
I showed this video to a friend who is "flat earth" guy, He told me that the video is malicious. his brain crashes like a windows blue screen. I just enjoy watching him crashing his brain while trying to explain me that the video is wrong.
lol kids are actually going for the concepts behind it and trying to explain it in natural words because thats all they know and the grown ups are just throwing random words they dont fully understand because they just heard it somewhere sometime LOL
Love that the only one who understood was a kid, and he knew nothing about the physics or proper terms, he just had the intuitive understanding of what happens in the world. Pretty neat
How is the globe supported on a thin layer of water? If the globe is so heavy, the water pressure has to be a lot to lift the globe and support it.. if indeed the pressure was so high the water would spray out at high PSI. On the other hand if it is a non recirculating pool of water the globe should have displaced the water by now. Someone please answer.. I would really appreciate it. I have been always curious about this.
We should always tell kids "You are good at it, I am proud of you for that. If you try a little bit more, I know you will excel in that" That's the way to go rather than comparing them and make them feel like, competing with everyone on every aspect of life.
proof that young kids are more intelligent before school ruins their ability to think. In the off chance the video creator is reading this, do you know a professor Greg Francis? His research was also into misconceptions.
I can not imagine the world you live in! Where children have more knowledge or reason before they go to school! Do you request a cardiologist that never went to school? Amazing!
vertical I did not know that. When I stick my thumb over the end of the water hose, and hold back the water for as long as I can, then let go, the water comes spraying out all the way across the yard.
The right hand rule generates torque based on current flow. When it was pinched down and shot out of the current that made it started spinning then. the direction of spin is based on primary current flow, magnetic flow, and the charge of the object.
Physics student: If I say enough key words maybe I'll stumble across the correct answer eventually.. 11 year old: Applies common sense and nails it in one.
+Morgan Mitchell that is another equation for it, ma is (kgxm)/sec^2 and mv/t is (kgxm/s)/s which is equal to (kgxm)/sec^2 .. Which one you use all depends on what kind of situation your solving for
romerobryan83 Okay, so mv = p = kg m/s. Because it's per unit of time, it's kg m/s^2 in the same way m/s/s = m/s^2. That's what I got from what you said. But wouldn't it be f = (delta)mv/t, because it's a change in momentum over time.
Morgan Mitchell dx means an infinitesimal change, or derivative. So dv/dt means a derivative of velocity with respect to time. Delta, a triangle symbol, means a difference or change in a value. f=(delta)mv/t, f=(mv-mu)/t (where t is a difference between two times) and f=m dv/dt are all equivalent forms. The dv/dt form is used in calculus.
"Force causes... change" is quite remarkable. He didn't nail it randomly, he really got it. That's impressive to see in an 11-year old.
Nicely put it's all about 'force causes .....change'. The boy got it.....
So he'd be about 20 now. I wonder what he's doing.
He is great.. it really seem like a spark in him.... like that maybe there's a spark in everyone

"Force causes change in speed", that's really very good for a 11 year old to be able to put forth that observation.
Idk man. Basically everyone in my class knew that. We were in 7 grade at 11 and everyone had learned that already. You learn plenty of basic physics in middle school
I love how the little girl, while using simpler terms for the concept, actually gets it pretty much exactly right.
I'm a bit late but ...
Children are creative genius. Our school system destroys the creative capability in nearly all of us.
you can check TEDx talk about it: ruclips.net/video/ZfKMq-rYtnc/видео.html
I honestly was really impressed by the kid. Although he didn't necessarily have all of the proper terminology (angular acceleration, torque, and angular speed), he still understood the concept of inertia far better than any of the other people interviewed. That kid is going somewhere in life.
bruh he kinda had proper terminilogy, he said force causes change in speed. if just instead of speed he told velocity that would be full proper definition.
Smart people aren't the ones who memorize everything on school and get good grades. Smart people are like that 11 yr old kid, who learns by himself and discovers the world by his own observations. That's how cience evolves, with new observations of people who think by themselves, not by doing Pitagora's algorithm.
You missed an "s"
that 11 year old...
***** Reminded me of my autistic niece. Briljant girl in her own way. Badly judged on things that doesn't matter. She's gonna be a great programmer one day. :)
no one need 8 years of physics lectures to understand physics. With good enough observation, even a 11 years old gets it.
Jay Theriver True that!
ParaditeRs
In today's society.
Jay Theriver I think it's great when the public is interested in science, but if you want to understand really fundamental, cutting-edge physics then you actually do need several years of education.
The kid at the end was the smartest one on the video which is awesome.
+Even Andy He wasn't confused by shitty science classes yet. Pretty amazing.
+Robert Which doesn't mean that every science class is shitty. Some definitly are... we need good teachers!
+Dust Rider I think the kid just didn't have any confidence, it was just so great to see him getting that boost that he needed.
That last youngster has more knowledge of physics in his little finger than all the other interviewees combined. Well done, lad, I predict you'll go far!
Lol that boy at the end ''k,k,yea,I guess,k" XD
yaaa
ROBLOXER BENEBOY Yeah he was pretty embarrassed from the flattery.
I officially LOVE how you speak to the kid at the end
Especially when you asked do people say you're smart? I think you're smart. Great work man. We need more people like you on this planet.
Absolutely agree!
2:07 The gave new defination for inertia
"It's too big to make it fast"
I edited this so it no longer makes sense :)
god damn man.. you made me wanna reply.. thats something.
Wow
Talska And now he studies physics because he clearly has it more than the other people in the video
I thought the exact same thing
I hope he sees this video if he doesn't
I wonder if younger people have an advantage because they don't think they know as much and because they are still in the stage where they are observing and learning.
As you get older you are hampered by the illusion you already understand your world.
i think thats caused by the way you grew up and learned/studied by reading things other people wrote/discovered, rather than learning trough your own thoughts/discoveries
Truly wonderful the mind of a child is...
@@Some_Awe Thats how science grows, by using the learnings or studies of others in the past
my hearth got broken because no single person said nothing about "inertia"... It warmth my hearth when finally someone said "change... in speed".
i learn more from youtube than form school -.-
milkerfish LMAO. Why doesn't this comment have more likes?
Maybe you should pay more attention at school? *from
I used to think British accents were cool, but then I heard this guy... 0:48
"Soooooaw strenngiee"
That guy officially has my new favorite accent *of all time*
***** My guess is: Japanese. But I'm not really an expert on accents!
+KitMellow I currently live in UK (I'm not british) and all I can tell that british accents are not as cool as people think they are. Some of them (yes, there are loads of different british accents) sound decent, but they're ugly and hard to understand most of the time
+omp199 yeah thats a japanese accent
test18258 Thanks!
HE IS KOREAN! you can hear him speaking korean a few seconds later guys, he isnt japanese
The 11 year old was able to answer very easily because he’s not over thinking. He’s mind is free to observe things without pressure or shame of delivering the wrong answer. The older we get, the more rules we put on our thoughts and we lose the ability to think freely like a child. Give the child a few more years and place him in front a camera and he will more than likely produce the same response as the older kids just because of how the brain functions. This is why a kids are scientists in a way by nature. By having the ability to maintain that curiosity into adulthood, can produce some of the best scientists we know to today.
Just hearing "change in speed" made me sigh with relief. How can someone who even took a physics course not know about inertia and mass's tendency to resist change in motion?
Because they miss that one word "change" when trying to reconstruct their memory of Newton's second law.
Because it's hard to figure out what is being asked on the spot.
i am not even in 11grade and a study quantum mechanics and learned most of classical physics
Do you want a medal?
Because that kid think. The adults dont think, they just guess and brust any random words. Thinking habit is rare nowadays.
Derek will be a good father.
*great
That kid answered every single question perfectly , on a roll
4:40 if this kids parents are watching this...we need kids like him!! Hope you guys will understand his capabilities and show guide him to the correct path in the coming future!! :D
I think at the end Derek should have told the kid about Newton. "Have you heard of a guy called Newton? What about his 3 laws of motion? What you just came up with was the first 2 thirds of newtons laws of motion." really inspiring.
Good job with the children mate, that kid at the end needed the encouragement!!!
you had my like, now you have my subscription.
2:21 that mommy is doing something sensual to the Earth O_o
dan16000 hahaha! i knew i'd find MILF comments on this video
haha milf pr0n
?
The 11 year old is exactly how I would answer.
"Ok"
"Sure"
"Ok"
"I guess"
you are 11 too?
he's so good with strangers. Making small talk. That baby he carries is probably his.
Oh man that 11 year old kid in the end is gonna be the biggest Astrophysicist!
Yeah I guess...
ok
Funny enough that 11 year old boy was the only one that got that the ball was accelerating when force was applied.. tho he didn't have the vocabulare to explain it.
lol im surprised absolutely everyone didnt say something that simple. I would have made it even simpler and said. Newton's laws of motion. Pretty much sums it up
seriously, everyone that veritasium talks to in this video is an idiot (accept for the babies). It's a very simple concept!
Lmao it's so simple yet as grown ups we often overthink things. The kid nailed it. I remember a test that was popular when i was a teen. Idk if it was made by Mensa or whatever but I vaguely remember the final results of the test. Something like 85% of all children answered correctly while 75% of adults when asked the same questions were incorrect. Simply from overthinking and making the problem harder themselves.
2:32 kid without formal knowledge gave correct answers everytime, just without using technical words
And everyone else, adult gave answer gravity, speed velocity
It's amazing
Someone, give that kid a degree!
"Do people tell you you're smart?"
"No..."
"Do you think your're smart?"
"No..."
"I think you're pretty smart."
"Okay..."
Gets me every time!
Damn this comment is 6 years old, and only has a handful of likes.
You deserve better ancient writing. Here, take my like 👍
blue shirt kid deserves a scholarship ... good luck kid, you're brilliant so far
Gave me goosebumps, a boy with so much interest because he want to know and know things. A good example for all of humanity.
other dude: "Friction?"
Japanese guy: "Soooooo Struanjiii"
ahahaha
Conversation at the end with the 11 year old was beautiful! Thanks for helping him start to see who he really is!
Here's my brain sitting here, thinking "wait, people didn't know?!"
rdococ There's lots of things people know that you do not know. Why make them feel bad for not knowing one factoid rather than another?
***** He didn't try to make anyone feeling bad imo, it is something you assume.
It is simply something that is obvious to me (and I assume him too) so it suprises you when there is someone that doesn't know. It is how people work, they take their own knowledge for granted.
Sabaca
That only works so long as you remain oblivious to the concept that everyone knows different things. Once you recognize this, being blown away by someone's ignorance is silly.
***** I don't get what you just said. What do you refer to with "that" and who's ignorance are you talking about
Sabaca
Being surprised someone else doesn't know something you find obvious or basic is silly.
Love the kids’ interactions! Good observations, a lesson in physics and a fun video. Nicely done, Derek!
Damn that kid did great. He pretty much came up with the Newton's 2nd law on his own. It was 9 year ago, I hope that he stayed sharp and is doing well in life today.
That kid did seem pretty smart, It was obvious the flattery was making him uncomfortable though lol. Perhaps a better approach would have been to have given him a physics book or Euclid's the elements... Basically Veritasium should try carrying around some books with him to give to the smartest kids he meets, who knows it might one day change the world.
Maybe he knowingly explained it after he thought about it
It was awesome that the kid noticed intuitively that F=ma and that dv/dt=a
***** Thank you for your ultracrepidarian opinion.
***** Please keep your stupidity to yourself.
***** Well somebody's pretty full of themselves...
That kid at the end is so humble
The kids just amaze me in how they are just observing and telling what's happening .. I guess scientists are just kids preserving their observation powers growing up 😄
Man I love your videos. You seem like such a genuinely nice person. What you do is really inspirational.
2:33 she doesn't have a hand so sad :(
Well she does have "a" hand. But I guess that's kind of the problem
victoneter but he is a boy
yes he does

I think the answer to this like force changes speed was known to those adults also but they are pre conditioned to be hesitant to answer thinking it'll be embarrassing if they were wrong, and the kids just let out there curiosity without thinking about any judgement from others and they were right, so the conclusion can be that being afraid of being judged can become an obstacle for your own learning
Is no one gonna talk about how adorable 2:20 is?
"two and a half tons of Inertia" - that's not the unit to use in this case. What matters is the moment of inertia, and that has units of kg m^2. It's not just the mass, but also how it's distributed about the axis of rotation.
A little bit of calculation, and taking the density of granite as 2,700 kg/m^3, and the moment of inertia of a solid granite sphere of mass 2.5 metric tons is 360 kg m^2.
When you go buy an Air-Conditioner. You say 1.5 Ton AC...
Here 1.5 Ton stands for 1500 Watt. Means 'Ton' is used as 1000 in common vocabulary.
So when he said 2.5 Tons of Inertia he said 2500 units of Inertia. The unit generally translate to the convenient unit. In USA they use Imperial units, in commonwealth countries they use SI.
@@HiQuantumSKY As it is, Americans do not use Imperial Units, they use US Customary Units, which are based on an older English system of units. Imperial units were defined by the Weights and Measures Act 1824. As the USA became independent in 1776, they never adopted them.
Hence an Imperial ton at 2,240 pound (known as a long ton in shipping circles) is about 10% more massive than a US ton (known as a short ton) at 2,000 pounds. As it is, the Imperial ton is quite close to that of the metric ton (1,000 kg) being equal to 1,016.05 kg whilst the US ton is equal to 907.185 kg
In any event, none of this has the slightest to do with the difference between using mass as a unit of inertial for rotational, which was what my comment was about.
For your information, the unit that would used for the moment of inertia using Customary American Units would be pound-feet^2. However, the universal standard in physics is to use SI units (and that includes in the USA; physicists there use SI units, just like those in the rest of the world).
That tons of air per hour is used on AC unit specifications in the USA has precisely nothing to do with this.
@@TheEulerID
I understand your point. And I know that mass alone cannot stand for moment of inertia. The size and mass distribution also important.
But when you are talking about a homogeneous sphere you can tell only mass as comparing factor for inertia. He just used 'Ton' in unprofessional way. And everyone gets that. That was my point.
And all you said about units and where they come from doesn't matter to our conversation.
By the way I'm also a physicist. I well understand difference between the both inertial quantities. The thing is in India we do use SI units. We know that other units are there but we don't bother about there values accept what British gave us before our independence.
.
@@TheEulerID
It is same in a way that when someone ask you your weight you dont tell them weight instead you say mass. So that was the catch to use Ton.
@@HiQuantumSKY That's completely irrelevant to the difference between inertia and the moment of inertia.
It's like describing the speed of a flywheel in metres per second rather than radians per second.
holy hell that kid nailed each of his sentences. He might not have used "acceleration" term but he really meant it
"You seem pretty smart for an 11-year-old. Have people told you you're smart?" "No" "Do you think you're smart" "No" "I think you're smart. Will you take my word for it?" "Ok" - Proof of failure of public education and commonly-held misconceptions of human intelligence in action right there! (See some talks by Sir Ken Robinson :) )
Just as important as being smart, the 11 year old is humble. The true seeker of scientific truth is ever humble.
Yet they all want discoveries named after them. I call bs.
@@Krystalmyth
"I discovered the 5th state of matter, from now it shall be called Geoff"
Most of the names are given afterhand, to honour the scientist
I love the ending, that encouragement is what (as a future teacher) I think kids need the most.
That 11 year old did better then most of them
Dude! That kid at the end is way smarter than he knows! I believe he'll go far in life
Yea, but more like everyone else was way dumber than they know.
your most recent video about synchronization discussed moons spinning around planets and showed you playing with your kids, then this video was recommended to me, in which you discuss rotating planets and you talk to kids. heartwarming!!!
one day when that kid grows up to be a great person or a scientist...
someone asks what inspired you ?
he is straight gonna say when i was 11 one person said to me he thinks i am smart.. and i took that to heart..
this video is from 2011 so that kid already grew
I showed this video to a friend who is "flat earth" guy, He told me that the video is malicious. his brain crashes like a windows blue screen. I just enjoy watching him crashing his brain while trying to explain me that the video is wrong.
Can you give us a couple examples for the record?
Last kid is what you call a scientist! I love his spirit of making conclusions by observing and thinking.
2:27 this kid is gonna grow up either becoming a physicist or an adult performer
Thank you for being awesome to those kids, and saying the 11 year-old was smart, that was the right thing to do, because it's true!
Absolutely true. More people like Derek would make the world a better place!
I love how he asks questions that challenge the way people think about the idea, rather than simply telling them the answer.
that 11 year old kid is now 20,i was 16 at that time,damn i feel so old i'm 25 now
lol kids are actually going for the concepts behind it and trying to explain it in natural words because thats all they know
and the grown ups are just throwing random words they dont fully understand because they just heard it somewhere sometime LOL
Love that the only one who understood was a kid, and he knew nothing about the physics or proper terms, he just had the intuitive understanding of what happens in the world. Pretty neat
I think it has more inertia than a toy globe and thus has greater tendency to continue rest or motion.
How is the globe supported on a thin layer of water? If the globe is so heavy, the water pressure has to be a lot to lift the globe and support it.. if indeed the pressure was so high the water would spray out at high PSI. On the other hand if it is a non recirculating pool of water the globe should have displaced the water by now. Someone please answer.. I would really appreciate it. I have been always curious about this.
No no one has answered it yet ..
MrAndrew7453 Thanks Andrew... seems logical, is this the same logic behind hovercrafts?
MrAndrew7453 Thanks, I was curious too. That makes perfect sense!
We should always tell kids "You are good at it, I am proud of you for that. If you try a little bit more, I know you will excel in that"
That's the way to go rather than comparing them and make them feel like, competing with everyone on every aspect of life.
Dat kid with the blue shirt though. Smart lol.
OMG, I just realised... It's BLUE SHIRT KID!!!
@@DanielDavies-StellularNebulla bruh cant believe this comment is 6 years old lmao
I am 11 years old and I love physics even though I haven't learned physics
Literally makes no sense.
makes perfect sense. physics is cool
Daniel Kranseler He loves physics but hasn't learned it yet...
I learnt from RUclips
And documentary TV programmes
love how you open people's minds! that interaction with the boy at the end was beautiful :) . You are awesome sir!
proof that young kids are more intelligent before school ruins their ability to think.
In the off chance the video creator is reading this, do you know a professor Greg Francis? His research was also into misconceptions.
I can not imagine the world you live in! Where children have more knowledge or reason before they go to school! Do you request a cardiologist that never went to school? Amazing!
Dale Robertson You're confusing knowledge and critical thinking/curiosity
Teens are the best
They have childlike imagination also adult type maturity
We know what a kid would know and an adult
Combining that makes us smarter
Veritasium: how do you make it go faster?
Little girl: *spits out complex mathematical equations*
Veritasium:

You go kid!
found this old i never saw and can see these little words of encouragement can push a person to do more.!!
i fricken knew the solar system when i was 3!!!
*****
I think he meant the planets and not the fact that it exists
you sir are correct!
Bro this comment is three years old
Well, done. Have a cookie.
I would get on top of that and start running. I'm curious how high the water would spray if the globe was not there.
Not much i think. Actually i dont think it wouldn't even spray.
Why? I think the worst that could happen is that I would fall off, or it would stop spinning.
Burak Baggins burak is correct...liquids can no compresd...
vertical I did not know that. When I stick my thumb over the end of the water hose, and hold back the water for as long as I can, then let go, the water comes spraying out all the way across the yard.
my english are not very good..what i ment was that you can not compress liquids like you can compress air...
The right hand rule generates torque based on current flow. When it was pinched down and shot out of the current that made it started spinning then. the direction of spin is based on primary current flow, magnetic flow, and the charge of the object.
Physics student: If I say enough key words maybe I'll stumble across the correct answer eventually..
11 year old: Applies common sense and nails it in one.
A young Isaac Newton at 3:49 lol. F=m dv/dt or Force=change in speed of mass.
Tony Spilotro Isn't it f=mv-mu/t? Force = change in momentum divided by time
Morgan Mitchell Change means 'per unit of time', so it's the same thing.
+Morgan Mitchell that is another equation for it, ma is (kgxm)/sec^2 and mv/t is (kgxm/s)/s which is equal to (kgxm)/sec^2 .. Which one you use all depends on what kind of situation your solving for
romerobryan83 Okay, so mv = p = kg m/s. Because it's per unit of time, it's kg m/s^2 in the same way m/s/s = m/s^2. That's what I got from what you said.
But wouldn't it be f = (delta)mv/t, because it's a change in momentum over time.
Morgan Mitchell dx means an infinitesimal change, or derivative. So dv/dt means a derivative of velocity with respect to time. Delta, a triangle symbol, means a difference or change in a value. f=(delta)mv/t, f=(mv-mu)/t (where t is a difference between two times) and f=m dv/dt are all equivalent forms. The dv/dt form is used in calculus.
The best definition of inertia:
It’s not hard to start it moving, it’s had to get it going fast
11 year old has a better answer than the physics student. I love it
