Simple Harmonic Motion: Crash Course Physics #16
ฝัง
- เผยแพร่เมื่อ 2 มิ.ย. 2024
- Bridges... bridges, bridges, bridges. We talk a lot about bridges in physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini talks to us about a particular mistake made in engineering the Millennium Bridge which allows us to talk about simple harmonic motion.

LOL "simple" harmonic motion I remember doing this in highschool, it was hard AF. Then engineering came and made me wish I was back in high school physics
@Unsung Songs I'm assuming because engineering is simpler than physics
D: this all sounds like really interesting stuff, I wish I understood it.
The death eaters also made the bridge swing even worse.
dangerouspeople1!!!!!!! Voldy made them do it
I thought the dementors caused it
Lol
They just said Expulso! and called it a day as they watched innocent Muggles spiralling into the Thames in their cars...
bahhbhbahbahhbahahbahhahbbhahbhabhahbhabhahbhabhahbhbhbhabhhabhahbhahbhahbhabhhab
The animation at 3:54 is god sent.
Sanjay Kulkarni true!
Exactly
This whole video is god sent.
Ifkr
I dont get it i mean there pretty good at editing but the whole vid is edited so why is this part good
Great video as always. I know some people are complaining about the speed of these videos, but I actually think it's great to have such an option. For people who learn better through longwinded explanations, they can watch khan academy, and people who learn better through quick and snappy explanations can come here. The great thing about the internet and the technological age is that there has never been a more customizable learning experience. There's something for everyone. Oh and unlike crash course organic chemistry, which barely helped me at all in my first semester of ochem, _this_ series actually will get you through calculus based-physics 1 and 2 in college. I love that you aren't afraid of alienating the fans by actually getting into the technical aspects, and believe that the experience and educational value of these videos has benefited profoundly for it. Keep it up!
differnce is khan academy actually teaches you something.. and doesnt just give general information directed to 10 year olds.

The problem is that in order for people to truly learn and remember the topic, they must go into much more detail and take a lot longer to explain it. The details stick instead of having information go in one ear and fly out the other.
@@dharitgabani7032 Not sure whether to take that as a compliment or an insult lol.
7:05 x=Acos-oh my god-t
Oh, my trig teacher would have gotten so angry with that...
Brackets brackets brackets!
hilarious
NERDS!!!!
i don't get it.
I love the way the period is derived, no calculus required.
I love how fast she talks. I can understand better than slow boring talking.
I honestly loved this so much. I missed a few lessons at school on simple harmonic motion and for physics I like to see how the ideas connect and don't really like just being thrown a bunch of equations and being expected to use them with no context at all. Loved this. Related all the equations beautifully + increased my appreciation for physics xox
The equation animations are marvelous. Thanks for the video.
It's awesome how all this correlates to musical frequencies--amplitude, resonance, oscillation. I can't wait to see your upcoming episodes on waves.
8:25 “today learned about *basically everything in SHM* in the space of about 5 seconds”
Her beauty eclipses anything that physics can achieve.
The pace is too fast for someone new to the channel but once you are used to it, you'll find it just right! I loved he videos and it's always been helping me with my Physics!
Excellent, damn useful for quick revision without having to read the whole chapter all over. Sticks to its name 'crash course'. Thanks!
That graph comparing the simple harmonic motion of the spring with the reference circle clears everything up for me!!!! THANKS!!!!!!
imagine this person in her childhood answering teacher's questions
I wish I had this episode when studying for my final high school physics exam last year, crash course is incredible.
Again a really nice video, I like the graphical examples for physical/mathematical expressions. As someone working in a university's institute for physical chemistry I know how many students even in higher semesters struggle with those topics. I really hope you make videos about thermodynamics, kinetic and quantum mechanics.
0.75x is the perfect speed
Bad Ice Cream omg yeahhh that's a lot better
the pace of these seem a bit fast, even for someone familiar with basic physical properties
That's why I keep pausing and/or rewinding the video
It's the benefit of the format.
Online videos of education are purposeful made at such a pace.
The intent is that for someone trying to learn via video, as opposed to learning via teacher in a class room, you can stop, rewind and watch the video at any point and any number of times. So for a broad audience, people that pick up more quickly, and those more slowly, can all utilize the medium.
Is .5 speed still too much?
...and scene
thank you so much for creating this course, as a student I have been struggling with physics for several years of my study. But these impressive work just brought physics home to me. Again, I appreciate the efforts the team has pour into this, love your work. Keep it up!
Really great video. I never saw a derivation for w=sqrt(k/m) without setting up the equations of motions and just using calc. That was really cool to see. The analogy with circular motion is something I don't remember seeing but I think thats a really great way to visualize it.
'We'll be talking about waves in our next three episodes'
Hype I'm looking forward to it!
Can't we take a moment and notice that this lady is very intelligent to be able to teach all of these physics episodes?
Excellent presentation of the topic with accurate animation and the real world example in the start of the video. Keep it up.
A huge thanks to the creators of this video for it helped me a lot. Congrats team you are doing a wonderful job. Keep going. Yay
Physics 220 final in about 12 hours and you're saving my life right now
These videos are so amazing for anyone studying introductory physics. Thank you so much Crash Course and Shini
I love the way you talk faster, don't change it ma'am, you make an hour video in some minutes, it saves our time
thank you !! physics made easy ;) I finally understood this concept
I learnt more than in 3 weeks of classes.. thx :)
I just learned simple harmonic motion in 10 minutes. What a great video
That was a much easier to understand explanation of simple harmonic motion than anything I heard in uni. But then again we needed to know how to manipulate the differential equations behind all of this.
This is very good. For those saying it's too fast.....well, i too have to pause and rewind quite a few times so that i can understand the material, but i don't think that detracts from it. There's a limit to how easy these guys can make it. Physics requires thought. Great job, Crash Course. Keep 'em coming!
very informative and comprehensive. I like that you focus more on concept rather that just memorizing formulae.
Excellent explanation and graphics. Thanks.
That’s a fast whooping time saving, concept clearing awsm video. All basic concepts are there....I learnt that in school in 90 mins....she did this in 10 mins....wow...
this is how cram lots of information in before a physics class, very helpful
This person should be given award, really helped me a lot!!!
I just love the way you explain...keep it up ...I just wanted to request you that Will you please explain "undamped ,critically damped & over damped vibration" in your next video?
Amazing! thanks you so much! I just sat with a notebook and write what you were explain! 1000 times better then my own Professor!
Hey!! I love these videos! Yhey teach me things that my school doesn't have time for!
Today I said to myself I would do my physics homework, then I went on TH-cam for an hour. Funny enough, I actually learnt physics today which was my original plan :D Thanks, crash course! I actually needed to learn this and my physics teacher is not good at all!
As a tauist, I can't help noticing all of those 2pi's.

Yesss!!!! They were driving me nuts!!!

Yeah, except that diameter is absolutely useless in math. There are infinite shapes with a uniform diameter, but only one, the circle, with uniform radius. If you want to talk about how things move in time, you're talking about eigenfunctions of the derivative, which give you exponentials, which give you trig functions, which are expressed in terms of the radius of the circle and the circle constant, τ. From harmonic motion, to periodicity of trig functions, to the complex exponential, to Fourier transforms, τ shows up as the fundamental circle constant. Only when a factor of a half is involved does π appear by itself.
perfect maam .i am an engineering student and you were amazing :)
Still nice to watch crash course. You rock!
Merci!
amazing video, take in mind you should have read all about SHM before watching, for this is only for better understanding and falling in love with physics. not learning from scratch for most people
Thanks a lot for everything. ❤️❤️
These videos are amazing.
Great video
perfect video, good job
Good Explanation on the Topic ...!!I am Loving it....😊😊👍
Thank you so much Crash Course!
Thank you so much, you are amazing!
This video was my first month of University Physics. It starts off so fun and easy...
All of you are such wonderful teachers ^_^. I understand this!
great lesson thank you so much
awesome video and the narrator is just brilliant!!!!! Her eyes tell all the equations of SHM.. but it was quite hard to catch up the pace of the video
Great video! Slightly fast paced, but nothing a little pausing and rewinding can't do. Don't understand some of the people that of they don't understand everything on the first moment they just go whining around that it's too fast. Hopefully they won't expect someone to cater on their learning preferences when they are in college.
Amazing explaination
great video!
Good job!!!
I have a test this Sunday and crash course is my only support
great video 😁
JUST IN TIME!! YOU ROCK
Oh my god I never thought I’d be able to watch a Crash Course with someone speaking at a normal rate instead of 2000 words per second
really useful thanks so much
I love this woman’s crash courses💜
Loved it....!
This video made me realize how bad my physics teacher is at lectures
Good video. In my physics class we were given these equations and it’s good to know why👍
wish I saw this before my first-year physics
because this is golden
Hello mam
I am from India&first time i watched your video which was very good to understand this lession.
THANKS A LOT OF
3:32 best explanation ever
Awesome!!!!
from 4;00 that eg is mind-BLOWING
gotta say though.....epic intro animations u got there. Kudos~
Hello! Thank you for a great video! I'm a physics teacher, I would like to know if I could use short parts of this video inside a video I am making on the same subject. My video will be in french.
This is great
Had to enable subtitles coz of the speedy explaino , anyways thank you! 😊
thank u it helps a lot ..
Thanks for the crash course Tahani
THANK YOU VERY MUCH
Please breathe
U are the BEST!!!!!!!! Shini
you lastly gave me a hint about the relation x=Acos(wt) i took it without understanding thanks alot
Thank you!
How does a particle (like the ball on the spring) exhibit an angular speed (omega) if its trajectory is linear? Also, wouldnt omega constantly be changing due to the changing velocity?
u r amazing.......thanks a lot..........
This was quick but complete.
Got a quiz on this tomorrow, wish me luck
I love ur videos
This video is saving my life in engg.
Cool video.
Check out some clips about the tacoma narrows bridge, that's an extreme case of what oscillations can do to a badly designed bridge.
We did a Crash Course Kids episode all about that bridge. TERRIFYING FOOTAGE!!!

+CrashCourse Where is the video 📹?
Right Here - th-cam.com/video/TcUX6eNT2j4/w-d-xo.html
The Tacoma Narrows bridge failed due to aeroelastic flutter, not resonance (at least, according to the mechanics professor from my degree). Aeroelastic flutter is a positive feedback effect: as the bridge oscillated and tilted, the wind striking it at an angle exerted a force. As the force cause the oscillation amplitude to increase, the bridge deformed to a steeper angle, exerting more force and deforming it to an even steeper angle until... well, y'know
Minute Physics has a great video explaining how the Tacoma Narrows case is not due to resonance.
wonderful... completed topic of SHM only in 9 min..
wish ic ould enjo my classes as much as i enjoy watching these videos
Question: at 7:05 if you were to translate this equation to the oscillating ball on a spring, would omega be just velocity max?
Thank you from UTD!
