So the initial angular momentum is the radius of the wheel times its mass times its speed. By flipping it over, the angular momentum of the wheel is reversed and negative, because the speed is now going the other way. For the total angular momentum (him and the wheel) to be preserved, he has to start spinning with a certain angular momentum, that when added to the reversed one of the wheel, sums to the original angular momentum before he flipped it. I hope that made sense
I literally had 1 interactive teacher my whole child hood. Im 34 now, he was 9th history teacher. My favorite class ever, and history was my least favorite subjuct. The difference is in whos teaching

The only teachers I actually remember are the fun ones, and things I learned that stuck with me . Seems like the world of education is being poisoned, and I can’t figure out why, how it benefits anyone to corrupt other peoples children. Not all teachers obviously, but some that have been brought into the spotlight
@@icthruyou4824 it would take a LONG while to explain exactly why schools are the way they are, but ill put it as simply as i can, the public school education system is obviously a governmentally run system which implys that its purpose is for the rich and powerful (because thats all the government consists of nowdays), those people usually have big corporations or agendas that need running.. now people that are to stupid to compete against big corporations (hence the rich and powerful) are what they need to keep running them, funny enough without them we wouldn't have our basic conveniences that we have, but thats besides the point, point is that its an indoctrination system designed with the soul purpose of "keeping them stupid" as they like to put it, teachers are just a cog in the machine in a way, they help indoctrinate kids and make sure they stay stupid because thats there job, most teachers who dont will get fired so thats why mostly all teachers seem boring and that keeps you from learning anything, now i understand this might seem kinda crazy or "conspiracy theory" type stuff but if you take some time to look at exactly who is benefiting from all this it will make complete sense
I'm 15 and a freshman in high-school, they don't teach shit 😂 I have 1 a because that's the only teacher that actually teaches the others just hand you a packet and get paid to be on their phones
Here's a summary of my teachers. English showed movies. Math do solve math problems until test. Socials basically a living audiobook. Physics and chemistry the most passionate charasmatic people you'd ever find.
Nothing is a good substitute for visual teaching. This will stick in a young kids mind more than reading it from a text book. Wish there were more teachers like this when I was in school.
I had a teacher that saved my life. My adoptive parents got divorced and neither wanted me. I was being abused at home, and i started to sleep on the bus until it stipp3d running. Then I'd walk around down town until I could go to her class, where she allowed me to keep items, clothing, she bought me soaps ans let me use the showers at school to get ready. One teacher saved me, gave me hope and I will forever appreciate teachers, and those that really care for their students. Ms. Dietz, you're a real one.
My older bother taught physics. When he got to centripetal force, he did a demonstration with a platform with strings that he spun, with an opened beer on the platform. Something a lot of college students can relate to 😂
@@connorcoultas9629 why wouldn’t he? Centrifugal forces are still very much a part of physics that should be learned, why is everyone in this comment section acting so smug?
@@ImTheBluestBird The idea of centrifugal force is generally very explicitly directed as not a force, and thinking there is a force there often prevents students from understanding what is actually happening. It is not intended to be smug, I would bet my money the teacher agrees with that. I was just pointing it out.
I was expecting it to turn, as soon, as he stood on it, with the wheel turning, but he didn't. So, I was like "Ok"...Then, he flipped it and I was like "WHOA!"
@@Jasonlovesmusic559 mine put a cinder block on my chest while I laid on a bed of nails. Physics teachers are lucky, they get to give some pretty dope demonstrations.
Some people can understand conservation of energy on paper, but most need to see the concept with a visual! It’s a great teacher that can adapt to relate to their students. 👍👍
I had a physics teacher like this in highschool. He did a demo for EVERY new lesson. Had a large walk in closet just for props/equipment. I dont remember most of the paperwork equations but I still remember all the real world examples he showed us.
Bro not every class can be taught this way. It's a physics class so obviously there is an easy way to demonstrate. Imagine trying to come up with something like this for literature, ecologicals or math.
For anyone wondering: the wheel's angular momentum vector was pointed up. When he forced the wheel around, the vector is now pointed down, so he now has to spin to compensate and conserve angular momentum. So he now spins in the opposite direction that the the wheel is until his angular momentum vector minus the wheels equals the old wheel vector
But how does that translate to him spinning? I thought it was the process of him spinning the wheel through 90 degree. the wheel is exerting a force tangential to the platform he standing on at that moment. I dont understand how a spinning wheel facing down is exerting a force to spin him around. If anything it should push him down instead of around.
i would love to hear him go into talking about it being torques when he said “outside forces well technically torques but we won’t get into that” i think it’d be very interesting
When he said ‘what do you think will happen’ it took me back. The best STEM subject professors and teachers will engage you with those questions right before they blow your mind with some science. Love it great job sir. Keep engaging those young minds.
I'm surprised more aren't because it's a subject where concepts are generally easily demonstrated by examples. I don't remember my physics teacher ever doing a practical demo. All we got were formulas to remember.
I wish I had teachers like this growing up. There was so much apathy and favoritism back when I was in school, it honestly made learning feel like torture. My teachers focused all there attention on the kids who did well.
It's just angular momentum. conservation of momentum. The wheel has some angular momentum. it's in a system with the platform and the human. when the wheels angular momentum decreases, the system has to compensate
The equation goes, omega(i, j, k) = omega(i, j, k) It basically means, if one objects turns one way, something else has to turn the other way. A bit like Newton's 3rd law but in a rotational sense
I’ll try my best… From what I remember studying angular dynamics, angular momentum (represented by the capital letter *L* , don’t ask me why) is the _dot product_ of the moment of inertia *I* and angular velocity *ω, or omega* . *L = I•ω (kg•m^2/s, or the change in inertia across a given time frame)* This is actually _much_ easier to remember if you have studied linear dynamics and are aware of the classic Newtonian equation for momentum which is ρ = mv where; ρ (rho) = linear momentum, m = mass, and v = linear velocity. Rotational dynamics essentially extrapolate linear parameters along a radius, usually so that you can determine the instantaneous velocity at any point of a rotating object; you can understand how that can be useful, e.g. determining the resulting output RPM of a compound system with knowledge of the input RPM (from an engine flywheel for instance) and diameters of the gears. That sort of thing… The linear and rotational equivalent parameters can essentially be substituted into already known equations. What do I mean by that? Well, take a look at the equation for angular velocity: *ω = v/r* - it’s just the linear velocity scaled along a radius, from the center of mass or pivot etc. (there’s a bunch of different rules depending on what you’re taking as a reference for the center that I can’t remember very well but anyways). The radius is inverted (1/r), because as you can imagine the linear speed of a wheel slows down the further you move out from the axis of rotation; velocity/radius are inversely proportional (this is actually a good way to remember this. It’s like how a gear works, bigger gears = slower output speeds)… [[[ In the same fashion, “moments” are essentially angular forces, because M = Fr. It’s actually another key component of angular dynamics, but alas I digress ]]] Hence; *L = Iω = I•v/r* Moment of inertia on the other hand is the rotational analog of mass used in angular dynamics. It must be specified with respect of the chosen axis of rotation. Because mass will not always be evenly distributed depending on how you rotate an object, this is why we use inertia instead. There are many many definitions for the inertia of different standard geometric shapes, and depending on how far you offset your measurement from this point it can get complicated…as in ”vectorially” complicated lol. But by far the simplest formula to remember is the one for a point mass; *I = mr^2* Essentially just the product of the object’s mass and the square of the radius attaching the force to the point mass. It uses the units *kg•m^2* . Hence, going back to the angular momentum of a point mass you get; *L = Iω = = I • v/r = mr^2 • r/t • 1/r = mr^2/t (kg•m^2•s^-1)* Which is how we get angular momentum. IN FACT…angular dynamics are _much_ easier to understand if you learn the linear-angular parallels. This took a few months for me to sink in back then but it really opened my eyes. So if you think this is bad, try learning the “cheat sheet” below; Linear Angular position x θ velocity v = x/t ω = v/r acceleration a = (v0 - v)/t α = (ω0 - ω)/t Newton Eq. v = x/t ω = θ/t v = v0 + at ω = ω0 + αt v^2 = v0^2 + 2ax ω^2 = ω0^2 + 2αθ x = v0t + 0.5at^2 θ = ω0t + 0.5αt^2 Mass/Inertia m I Force/Moment F = ma M = Iα Momentum ρ = mv L = Iω Work W = Fx W = Mθ K.E. 0.5mv^2 0.5Iω^2 Power P = Fv P = Mω As you can see they’re all just rotational analogs of the linear equations… This is why I love mechanical engineering; all of the equations you learn tesselate with each other beautifully and they just…work…you don’t even need to learn formula. As long as you know the basic concepts you just throw in the variables and it turns out it is the formula anyways… But there you go, a crash course into angular dynamics lol
I wish all teachers taught like this, after 10+ years i finally understand what actually happens to the direction of momentum when you flip/let go of the spinning wheel🔥 love from the UK
This is how you teach, you don't force the subject on students instead you present the subject in a way that the students themselves want to explore it further.
@@sitproperlywhilewatchingph423 an object in motion stays in motion until affected by an outside force. Every action has an equal and opposite reaction. Him flipping the wheel allowed the angular momentum acting on the wheel to pass through him and act on the wheel below his feet. Something to that extent. It's possible to break it down further but I don't feel like Googling it so I'm drawing from memories of a science class over a decade ago.
Man, teachers like this should be a requirement. Literally every teacher I had throughout kindergarten-12th grade just had their pre-planned lessons with zero enthusiasm. Maybe if I had teachers like this growing up I wouldn't have the mental capacity of an ant
I mean this short demonstration doesn't take away from the math involved in physics and that is generally what prevents students from caring about the subject.
@Connor Coultas I've actually always loved math, I though I would enjoy physics and was excited for the class but it was so dry! Literally everything we learned was straight out of a book and most the class didn't understand what he was talking about half the time.
@@sammieh9695 I definitely agree that a teacher like this is super helpful. My physics teacher in high school was a baller and then in college he was super boring and plain. The teacher can certainly make a huge difference regardless of the math!

Always loved teachers like this, actually learn and didn’t mind being in class.
That's what happens when you like your job, when you aspire to become a teacher, exact opposite of Asian especially indian teachers.
The only teachers I actually remember are the fun ones, and things I learned that stuck with me . Seems like the world of education is being poisoned, and I can’t figure out why, how it benefits anyone to corrupt other peoples children. Not all teachers obviously, but some that have been brought into the spotlight
@@huskiehuskerson5300 I have had several asian professors that loved their job.. Though they taught more lax classes
@@icthruyou4824 it would take a LONG while to explain exactly why schools are the way they are, but ill put it as simply as i can, the public school education system is obviously a governmentally run system which implys that its purpose is for the rich and powerful (because thats all the government consists of nowdays), those people usually have big corporations or agendas that need running.. now people that are to stupid to compete against big corporations (hence the rich and powerful) are what they need to keep running them, funny enough without them we wouldn't have our basic conveniences that we have, but thats besides the point, point is that its an indoctrination system designed with the soul purpose of "keeping them stupid" as they like to put it, teachers are just a cog in the machine in a way, they help indoctrinate kids and make sure they stay stupid because thats there job, most teachers who dont will get fired so thats why mostly all teachers seem boring and that keeps you from learning anything, now i understand this might seem kinda crazy or "conspiracy theory" type stuff but if you take some time to look at exactly who is benefiting from all this it will make complete sense

Nothing is a good substitute for visual teaching. This will stick in a young kids mind more than reading it from a text book. Wish there were more teachers like this when I was in school.

The more I see this guy the more I look up to him like an Uncle. It's an extreme understatement to say we need more teachers like him.
I had a teacher that saved my life. My adoptive parents got divorced and neither wanted me. I was being abused at home, and i started to sleep on the bus until it stipp3d running. Then I'd walk around down town until I could go to her class, where she allowed me to keep items, clothing, she bought me soaps ans let me use the showers at school to get ready. One teacher saved me, gave me hope and I will forever appreciate teachers, and those that really care for their students. Ms. Dietz, you're a real one.
Thank you for the valuable lesson, Physics Jesus. 🙏

My older bother taught physics. When he got to centripetal force, he did a demonstration with a platform with strings that he spun, with an opened beer on the platform. Something a lot of college students can relate to 😂
Hopefully he explained that centrifugal force is a fictitious force.

@@connorcoultas9629 why wouldn’t he? Centrifugal forces are still very much a part of physics that should be learned, why is everyone in this comment section acting so smug?
@@ImTheBluestBird The idea of centrifugal force is generally very explicitly directed as not a force, and thinking there is a force there often prevents students from understanding what is actually happening. It is not intended to be smug, I would bet my money the teacher agrees with that.
I was just pointing it out.
No matter how much they try, angular momentum is beyond my grasp. It's magic!
I was expecting it to turn, as soon, as he stood on it, with the wheel turning, but he didn't. So, I was like "Ok"...Then, he flipped it and I was like "WHOA!"
This guy deserves a raise what a great teacher.
If every teacher was like this that would be great having a visual to how things work is a great teaching tool.

Physics teachers are lucky, they get to give some pretty dope demonstrations.
Some people can understand conservation of energy on paper, but most need to see the concept with a visual! It’s a great teacher that can adapt to relate to their students. 👍👍
I had a physics teacher like this in highschool. He did a demo for EVERY new lesson. Had a large walk in closet just for props/equipment. I dont remember most of the paperwork equations but I still remember all the real world examples he showed us.
This is exactly a good example of how teachers should interact with students and make the class fun
All of the teachers in my life HAVE been like this
I dont know I saw the movie 187 and I didn't really help in the end.
Bro not every class can be taught this way. It's a physics class so obviously there is an easy way to demonstrate. Imagine trying to come up with something like this for literature, ecologicals or math.
For anyone wondering: the wheel's angular momentum vector was pointed up. When he forced the wheel around, the vector is now pointed down, so he now has to spin to compensate and conserve angular momentum. So he now spins in the opposite direction that the the wheel is until his angular momentum vector minus the wheels equals the old wheel vector
For anybody interested, look up Vsauce's video on the law of conservation of angular momentum.
But how does that translate to him spinning? I thought it was the process of him spinning the wheel through 90 degree. the wheel is exerting a force tangential to the platform he standing on at that moment. I dont understand how a spinning wheel facing down is exerting a force to spin him around. If anything it should push him down instead of around.
🥱

Why didn't I ever have a fun teacher like this ins school. Makes physics a lot more fun.
When he said ‘what do you think will happen’ it took me back. The best STEM subject professors and teachers will engage you with those questions right before they blow your mind with some science. Love it great job sir. Keep engaging those young minds.
Now that's how you get students to understand and like you, showing an example, actually makes the lesson memorable
Having the whole class engaged in their thoughts and expressions really gets a class moving with his energy.
Bruh mad respect my teacher taught the same thing but didn’t give a cool demonstration and left me confused

I'm surprised more aren't because it's a subject where concepts are generally easily demonstrated by examples. I don't remember my physics teacher ever doing a practical demo. All we got were formulas to remember.

Great demonstration! This is a physic that is lost and overlooked so much!
This class always got me. Not cause I was confused, but because it was always so cool
I literally asked out loud: “How the fuck does that work?”
- Now I want to know the equation and verbal explanations.
Me too, omg
It's just angular momentum. conservation of momentum. The wheel has some angular momentum. it's in a system with the platform and the human. when the wheels angular momentum decreases, the system has to compensate
The equation goes, omega(i, j, k) = omega(i, j, k)
It basically means, if one objects turns one way, something else has to turn the other way. A bit like Newton's 3rd law but in a rotational sense
I’ll try my best…
From what I remember studying angular dynamics, angular momentum (represented by the capital letter *L* , don’t ask me why) is the _dot product_ of the moment of inertia *I* and angular velocity *ω, or omega* .
*L = I•ω (kg•m^2/s, or the change in inertia across a given time frame)*
This is actually _much_ easier to remember if you have studied linear dynamics and are aware of the classic Newtonian equation for momentum which is ρ = mv where; ρ (rho) = linear momentum, m = mass, and v = linear velocity. Rotational dynamics essentially extrapolate linear parameters along a radius, usually so that you can determine the instantaneous velocity at any point of a rotating object; you can understand how that can be useful, e.g. determining the resulting output RPM of a compound system with knowledge of the input RPM (from an engine flywheel for instance) and diameters of the gears. That sort of thing…
The linear and rotational equivalent parameters can essentially be substituted into already known equations. What do I mean by that? Well, take a look at the equation for angular velocity: *ω = v/r* - it’s just the linear velocity scaled along a radius, from the center of mass or pivot etc. (there’s a bunch of different rules depending on what you’re taking as a reference for the center that I can’t remember very well but anyways).
The radius is inverted (1/r), because as you can imagine the linear speed of a wheel slows down the further you move out from the axis of rotation; velocity/radius are inversely proportional (this is actually a good way to remember this. It’s like how a gear works, bigger gears = slower output speeds)…
[[[ In the same fashion, “moments” are essentially angular forces, because M = Fr. It’s actually another key component of angular dynamics, but alas I digress ]]]
Hence;
*L = Iω = I•v/r*
Moment of inertia on the other hand is the rotational analog of mass used in angular dynamics. It must be specified with respect of the chosen axis of rotation. Because mass will not always be evenly distributed depending on how you rotate an object, this is why we use inertia instead. There are many many definitions for the inertia of different standard geometric shapes, and depending on how far you offset your measurement from this point it can get complicated…as in ”vectorially” complicated lol. But by far the simplest formula to remember is the one for a point mass;
*I = mr^2*
Essentially just the product of the object’s mass and the square of the radius attaching the force to the point mass. It uses the units *kg•m^2* .
Hence, going back to the angular momentum of a point mass you get;
*L = Iω = = I • v/r = mr^2 • r/t • 1/r = mr^2/t (kg•m^2•s^-1)*
Which is how we get angular momentum. IN FACT…angular dynamics are _much_ easier to understand if you learn the linear-angular parallels. This took a few months for me to sink in back then but it really opened my eyes. So if you think this is bad, try learning the “cheat sheet” below;
Linear Angular
position x θ
velocity v = x/t ω = v/r
acceleration a = (v0 - v)/t α = (ω0 - ω)/t
Newton Eq. v = x/t ω = θ/t
v = v0 + at ω = ω0 + αt
v^2 = v0^2 + 2ax ω^2 = ω0^2 + 2αθ
x = v0t + 0.5at^2 θ = ω0t + 0.5αt^2
Mass/Inertia m I
Force/Moment F = ma M = Iα
Momentum ρ = mv L = Iω
Work W = Fx W = Mθ
K.E. 0.5mv^2 0.5Iω^2
Power P = Fv P = Mω
As you can see they’re all just rotational analogs of the linear equations…
This is why I love mechanical engineering; all of the equations you learn tesselate with each other beautifully and they just…work…you don’t even need to learn formula. As long as you know the basic concepts you just throw in the variables and it turns out it is the formula anyways…
But there you go, a crash course into angular dynamics lol

Teachers like this is why I chose the STEM field as my career trajectory. Keep it up!
I joined STEM this year, how is it like for you?
I always enjoyed the teachers that actually got into the subject and made it fun instead of just reading from a book or prompt
This is how you teach, you don't force the subject on students instead you present the subject in a way that the students themselves want to explore it further.
Engaging the students without staring at a computer screen is a great way to teach. Well done sir.
I like how everyone’s like “wow we need teachers like this” which i do agree with but like no one’s talking about how fascinating this actually is
I think the point people are trying to make is that this teacher teaches the students about this in a way that makes it fascinating for them.
Can anyone explain the reason behind why he moved when he Turned the wheel in specific Direction ?
@@sitproperlywhilewatchingph423 an object in motion stays in motion until affected by an outside force.
Every action has an equal and opposite reaction.
Him flipping the wheel allowed the angular momentum acting on the wheel to pass through him and act on the wheel below his feet.
Something to that extent. It's possible to break it down further but I don't feel like Googling it so I'm drawing from memories of a science class over a decade ago.
