Very impressed by the presentation of information and how it is nice and compressed to cover everything required. And funny too which actually makes information more memorable. Thanks so much! This saved me from failing Engineering Statics Class~
lol yea sure, it's the Saudi/muslim way of saying; "May god fill your life with happiness". The way you pronounce that phrase is: (Allah ysedik ya sheik).
I didn't find anything like "i", "j" and "k" or simply Dot and cross products. Is it because these are other than motion in 1 dimension or something else??
That is because you don't have to use unit vectors "i", "j" and "k" to work with vectors. Dot and Cross products are for Work and Torque, etc. If you want to see a lecture about components using unit vectors, I have one here: ruclips.net/video/S9hPYnYWNSQ/видео.html
+ihonestytruthful You are welcome. I was very excited when I figured out a could make a slow moving car to show vectors and relative motion. Fun stuff!
Sorry guys please correct your posting. Please note sin(th)=O/H=|d_y|/|d|; NOT vec_d_y/vec_d as you wrote; same with cos(th). You should not use vector signs there for cos and sin. Otherwise, an enjoyable presentation.
Yes. Thanks for these. I realize this is incorrect now. I really wish RUclips allowed educators to upload corrected versions of videos, however, that is not something they allow!
well little by little I get it,I never did physics in school but now I'm forced to do it anyways any advice you could give me that will kind of make me understand it better.Thank you
Near the end of the video I talk about this. You need to remember that dx and dy are _vectors_ not _scalars_ . Because dx and dy are vectors, you need to use the Pythagorean theorem because they form a right triangle with d.
I have a question and please please I need the answer ..why when we find the tangent for the x and y components sometimes we must find the reference angle ..why ? Is the angel that we got from the tangent wrong ? I noticed that we find the reference angle when we have a negative value of x or y ..is that true? I hope that you understand my question ☹️
The angle which describes the direction of a vector is at the "tail" or "base" of a vector and not where the arrow is drawn at the "tip" or "head" of a vector. Some teachers require this angle to be a "reference angle"; I do not. A reference angle is always less than 90 degrees and starts from the x-axis. In other words, if the vector is at an angle of 25 degrees E of N, that does not use a reference angle. It would need to be changed to 65 degrees N of E to use a reference angle. (Because 25+65 add up to 90 degrees). Here is a webpage that describes reference angles pretty well. math.tutorvista.com/geometry/reference-angle.html Hope that helps.
@@FlippingPhysics you work so hard on all of your videos, thank you for making what is usually such a hard course for students an enjoyable experience for people even outside of your classroom
Test tomorrow, worth 10%, very stressed. I love you. I do not understand my teacher but you, You are a genius.
Thanks for the love. I hope the test goes/went well today!
How was the test bud?
@@maurovisosoleach8540 Tbh bro def forgot
This video is amazing. I especially love that you have the student characters asking common questions as you go, thank you so much.
You are certainly welcome.
This stuff is worth 10 % on my exam. You are a huge help man.
Good luck!
the students have lots of character development
I'm not sure what you mean.
from the first episode, you can tell that their knowledge grows from a seed to a tree
btw my teacher makes us watch this

this is very creative and very informative, cudos on creating a well thought out educational video.

Lovely compliment. Thank you!
Thank you for this helped me for my midterm!!
You are welcome!!
I hope the midterm went well.
I appreciate all your videos thank man!
I've never had so much fun learning physics! Allah ys3dk ya shee5! XD
So glad to help you enjoy learning. Any chance you can explain what you mean by "Allah ys3dk ya shee5! XD

I am a high school student and love physics. Thanks for the great videos
Glad to know I can contribute to your love of physics!

Thanks. I enjoyed making "Slow Velocity Racer"!
Good, Dynamic and informative :D
thanks bro this really help me out please upload more and more videos like this.....
You are welcome. Don't worry, I'm always working on more video.
Who is your crew for this online show?
This video answers your question: flippingphysics.com/making-a-video.html
Thanks, I think I get it. Gosh, I'm assigned to report this topic on monday.
Hi, can you explain why you did inverse tan?
When looking for the angle you have to use inverse tan/sin/cos. When looking for length, you don't.
Okay, thanks!
Awesome dude! Thanks
Great Video !

I present a piece of advice in this video which may be helpful to you:
flippingphysics.com/understanding.html
Thank you so much
Is your statement that dx + dy = d (vectors with x and y subscripts) really true, if you have to square each of the numbers?
Near the end of the video I talk about this. You need to remember that dx and dy are _vectors_ not _scalars_ . Because dx and dy are vectors, you need to use the Pythagorean theorem because they form a right triangle with d.
I c you've got a engineering ring :)
Cool video
I literally focused on why there are 4 of you instead of focusing on vectors XD
Watch this: flippingphysics.com/making-a-video.html
And then rewatch this video.
Ok how would i find the components of X and Y if the vector that was given to me was 50N and the angle was 20 degrees?
here is a picture if you didn't understand what i said. gyazo.com/ee7738060f535123b0511f9e4e46f3ad
Dude. Watch the video. That is what I show you how to do in the video. The numbers may be different, however, the process is the same.
thank you ! entertaining. :)
You are welcome. Glad to simultaneously entertain and educate.
Thanks...
what if the magnitude is negative? how can we change the angle to get a positive magnitude??
Do I add 180°?
Yes. Negative North is the same as South. Negative East is the same as West. Negative West is the same as East, etc.

what do we do when thetha is 127degrees
Switch to using the angle which is on the other side, the one that is 180 - 127 = 53 degrees.
+Flipping Physics sin and cos both will be positive?
In physics we typically have all angles be positive and describe direction using cardinal directions:
