Rotational Motion: Crash Course Physics #11

Did you know that at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of rotational motion!

Binge the whole series at 2x speed to ascend to a higher level of consciousness

If you're not getting it the first time. It might be a good time to review your textbook, speak to your instructor/tutor, or simply, rewatch whatever portions of the video you do not understand. That is it. It is fortunate that CrashCourse is producing such high-quality videos and squeezing large volumes of content into ~10 minute videos FOR FREE. Great work CrashCourse keep it up and keep the same style of videomaking.

Wow i WISH i could speak this clearly and this quickly at the same time 👏🏼👏🏼

[LeFancyTopHat]

As a veteran physics tutor, I approve. You guys covered a lot of common points of confusion. Well done!

Brings back memories from long ago, when I was studying mechanical engineering. Nice to see that I did not forget everything, as I ended up in IT and actually never worked in anything related to what I studied. But I am not sure how the normal audience manages to keep up with this series. I personally like it.

Watching it as a review the first time blew my mind indeed (it has been 7 years since my last physics class), but re-watching it does help. It made more sense to me the 2nd time around.

An open letter to those who complain about the content delivery:

Isn't it lucky that the information is being belied in a format where pausing, slowing down, and rewinding are all options? It isn't my intent to offend, but this video probably isn't exactly for you. That isn't to say crash course doesn't want as many people to enjoy their content as possible, but the original purpose was to be a resource for AP student. As someone who is currently in AP Physics and on this unit, this wasn't too fast. That's not to say that students are expected to catch everything just by watching it the first time through. But the students here are either watching it for a preview before class, an additional perspective, or a review before a test. No one is meant to walk away form crash course with a physics major. These are meant to be fast videos to give a basic understanding to curious internet goers and to help students learn and study.

Best wishes,
Vicki

I do not understand what people complain about .
The speed of the speech is proper, just what you need to obtain the information . Actually as a physics student I find this series very useful, quick way to get an overview of the subject with relevant visualizations and without too much algebra . Nobody said that the course provides a PhD, this is a great way for somebody who already knows the subject to rehearse and see the physics a little bit clearer, without the algebraic fog . For someone who hasn't studied physics at academic level, this would be a great way to understand the idea of physics behind everyday phenomenons .

uhuh, yup, yes, alright, oh!, okay okay. yeah
wait.
what?

Having an American physics teacher and a British crash course host has rly heightened my awareness on how much pronunciation differs b/w the countries

[oshkoshbjosh]

To everyone criticizing the speed of delivery, it's called "crash course"--not hold your hand and wipe your nose physics

[TheCaseyKlinger]

These videos are awesome! I didn't have time to read any of my textbook before my physics test, so I just watched these videos for all 4 of my chapters and I got an 87 on the test!!

I love the way she talks and the speed at which she talks. It's perfect. She gets all the important details in

[timperry]

It's actually pretty easy to understand and visualise.

The wheel is basically pivoting on a constantly moving point. When a point is at the bottom, it is the pivot so, like a fixed pivot such the hinges of a door, it isn't actually moving even though the object is.

It good for revision.but hard for 1st time learning

[TheFireflyGrave]

What goes around, comes around I guess.

[Bitsmap]

These videos are going to help me a lot at the test to get to the college. And once I get there they will help me on getting better physics at the games I will create.

[downtownwoodstock]

I love your videos. I have a hard time to pay attention when videos are slow and boring. this is great
