360 degrees, the 60 second min, and the 60 min hour are based on how ancient Sumerians counted using their fingers over 6000 years ago. Each finger has 3 bones so a single hand containing 4 fingers(not thumb) had 12 nodes that could be pointed to using the thumb. On the other hand you have 5 digits(including thumb) that could be used to tally each set of 12 that you reached. With 2 hands you could count 5 sets of 12 all the way up to 60. Everything was BASE 60 in their calculations.
This is the best explanation of angular velocity that I have found on the internet. The direction in z in particular is what has thrown me off, at this stage I just don't see the point of using the inwards our outwards z except for saying whether it's turning clockwise or counterclockwise. As well as satisfying the definition of velocity which is that it has a direction. But it isn't actually moving in that direction, it's more the case of using a direction for the purpose of observation.
thank you very much. I am currently programming a game that uses physics and I needed to thoroughly understand angular velocity and its relation to linear velocity in order to make it work properly. Your video delivered clearly in a way my highschool education never did, thank you so much
right-hand/thumb rule means that in jutsu: rotation with right arm down and rotation with left arm up is same, and vice versa; meaning that each arm/leg has opposite direction=the same motion
think of it like this, the centripetal acceleration is towards the axis of rotation now take the component, it points upwards, and then take the acceleration(net) and take its sin components, youll find that it coincides, that is the actual centripetal force in application, which is why its upwards, this is balanced by the reverse axial vector provided from the other side, thats how it remains in plane while still accelerating, now i dont know how much of this is accurate but this is how i visualize it to be in motion, but if you want mathematical answer then it's simply cross product
Sir If angular velocity is angular displacement / time And displacement cannot be more than 2pi why in questions angular velocity is more than 2pi rad/ sec?
It is not clear why if there is a rotational movement there is a perpendicular vector. After all, the linear velocity is a vector tangent to the circle and it is not perpendicular but on the same surface of the circle of the disc
I just took a two semester, year-long course of Math 55 in Cambridge, Massachusetts at Harvard University, learning from world-renowned mathematics professor Denis Auroux and I still could not solve for who the fuck asked
That's simply for your teachers failed to engage you with it. Physics and mathematics are absolutely wonderful once you see some of the applications of either. Especially if you have a knack for anything related to engineering

Why is this video underrated? this man is a genius
I cannot express how much gratitude I felt hahaha. Literally, final tmr and haven't read a thing, barely listen in class. VERY VERY big thanks
Despite being 4 years old video, I get much information than I thought.
Thanks ❤
Thank you for the background information on symbols! Helps understand the big picture!

Sharrrrrrp
What
Amazing clarity and flow!! Thank you Sir!!
from all the explanations this one made things clear for me . THank you a lot.
You’re welcome
Love Love your explanations and the visuals. Great teacher! Thanks so much.
Thank you

Glad it helped
Amazing Explanation...i didn't know how the value of Pie is till now but you made it clear
Amazing teaching, Thank you sir.
Very well explained. Thank you!
Thank you! This video was very useful!
Nice lecture sir (from Bangladesh)

your explanation is exellent
Well done. From a teacher myself
Thanks!
Why is the the direction angular velocity defined the way it is?
Can you show that such a quantity really exists in that direction?

dude i gotta test tomorrow tysm
Absolutely Great video. Love your work
Thanks.
Explained very well sirr.
Amazing explanation!!
Sir
If angular velocity is
angular displacement / time
And displacement cannot be more than 2pi why in questions angular velocity is more than 2pi rad/ sec?
Angular displacement can be more than 2π. If it spins three time it’s now 6π

Nice video mate. Really clear and thorough with diagrams and great explanations.
Thanks form Australian Sydney
Thankyou. And I’m not far away. In the Macarthur region. 🤓
Thank you very much sir. helped a lot.
The video helped me a lot...thank you!
Saved my life
thank you..it was very helpful!!..Bless!
aAgular velocity is very similar to the motion of an object except that angular velocity doesn't take the inertia or mass into account, I'm I right?.
Plz tell me that angular velocity be infinite or not???
Shouldn't rotational displacement = Theta in radian * radius ?
nvm i forgot it's called *angular* velocity
thank you
I just feel I have to say it by myself, so... THANK YOU VERY MUCH XD
Thank you.
God Bless❤
Same to you!
His voice reminded me of serveus snape.

Your the best
Thanks
*You're
thnx Sir
Most welcome
PLzz keep making videos
Sure will. Please share.
360 days in an Ascendant Year, because the Ascendant Zodiac varies four minutes every day
Nope 360 degrees come from Egyptians
They add 6 triangle in a circle.
Do your research

@ Yasser Yak Well if you had teachers like this guy , I can understand why.

You digressed way too much. I clicked for angular velocity, not a crash course on angles.
