Do you know The Office's "Explain to me like I was five" joke? Dude, you just saved my night, for I couldn't sleep thinking about the r-hat components.
For real, I appreciate your effort, no other professor did this amount of detail. Thank you so much 💙
Glad you liked it!
Wow! That was an mind-blowing explanation. Crystal clear. Thanks!
There cannot be a better explanation than this. Thankyou sir, keep up the work
One of the underrated UA-cam channels out there😢
i created a UA-cam account just to freaking thank you man
phenomenal explanation!!
i hope i see more of you and keep it up mate!
This is what I justtttttttttt need! Crystal Clear and understanble. Keep up the good work, Handsome! 👏
Best explanation on r hat. Tq
Been looking for this explanation forever! Thanks a lot
Thanks bud , It clears my conceptual problem.
Very good explanation😊
Thank you so much for this
Thnx! Just what i needed!
Thank you very much ❤
Thanks a lot it was very useful and you made it look easy. Love from India
Too good
Refreshed my memories
Please/ I need formula of unit vactors in spheric coordinates.
r^/theta ^ and fay^
How can we convert from polar to cartesian unit vectors?
Fantastic
Thank you sir
could you please upload example question video how to solve cylinder coordinate system question? and please give me some idea to solve quickly.
If we use a polar coordinate system whose origin is either 1) moving with uniform velocity or 2) accelerating or 3) itself moving around another fixed point, can we use Newton's second law in the r hat and theta hat directions.
I suspect we can still do so in case 1) but not if it's accelerating in 2) and 3).
If not, how would we deal with such a system with an accelerating origin: I'm thinking something like a spinning ride which is itself on a spinning carousel.
Hopefully you can comment on this.
Thanks.
Hi, can you explain why the position vector can never be described as a linear combination of r hat and theta hat whereas the velocity and acceleration vectors derived from the position vector are described in terms of a linear combination of r hat and theta hat. Indeed it seems velocity and acceleration vectors at each position are uniquely suited to this coordinate system since they are true vectors unlike the position vector (which starts at the origin and therefore only has an r hat component). This difference (between position vectors and their velocity/acceleration counterparts) seems to extend to the ability to take dot products in this coordinate system as well: dot products don't work for position vectors. Can you shed light on what all this means. Is there a deeper physical significance associated with this difference in the treatment of vectors which doesn't happen for the Cartesian coordinate system. I heard reference to velocity and acceleration being true vectors in the tangent spaces of each point etc and this fits well with a changing basis at each point (as with this coordinate system). I hope you can shed light on this.
😀😀😀 EXCELLENT
But I really don´t get why we put these unit vectors on the point we are locating, and is strage because we localizate points with basis vectores in rectangular cordinates, but her we fist locate the point and before we put on it the basis, no sense for me.
THANKS FOR YOU ANSWER.
