Thank you so much for this video. I'm taking electricity and magnetism in university and love how much information you went through in such a short video, great work and great explanations, better than my professors! I wish schools would give us an overview of the course before going into details because it seemed pointless to study point charges, electric fields, electric flux etc without knowing their impact, although, after watching this, it is clear! Thank you!
Thank you for making these videos ;) They are not only helping AP students but physics majors as well. Even though the examinations from university are at a higher standard, the basic intuition and conceptual understing you can get in your videos is just amazing and a great starting point. Please keep up the awesome work!!
Thank you so much, you have no idea how much you have helped me out (with all your vids, not just this one) in getting an intuitive understanding of these topics.
This is the video i watched and ended up getting a 5, it was a great review, But more than anything else PLEASE DO PRACTICE PROBLEMS. Videos will only get you so far
Bro this video sooooooooooooo gooooooddddd I feel so prepared and knowledgeable now for my final tmmr I hope I do well 😢, but I’m feeling good about it rn thank you so muchhhhhh for this video omh I just want to hug you sir !!
At about 24:10 the statement about current when R increases has some mistake, the area under I(t)should be the same, thus then R increases, the starting point of I(t) should be lower with lower gradient, vice versa. Very Nice video btw
At 27:44 you said to point our pointer finger gun to our face but since the field shows that it’s into the page according to the circles with a dot in the middle of them, wouldn’t that mean that the force (middle finger) is to the left and not the right. Thanks for the amazing content by the way.
E = -dV/dr, dV = -E dr To prove this, derive V with respect to r: V = kQ/r = kQ * r^(-1) dV/dr = (-1) kQ * r^(-2) = -kQ/(r^2) -kQ/(r^2) is essentially just -E, given E = kQ/r^2 So from there, we have: dV/dr = -E dV = -E dr I hope that was helpful!
@@AgentJRock805 I have calculus based physics. I know it essentially means derivative. But I can't understand that relation intuitively. Like, Electric field is change in potential over distances?

decided to "self study" for e&m (haven't looked at any of the material) but this video gave me a little more hope for my exam day after tomorrow
Same 💀💀
Watched this last year day before the exam, got a 5. Glad you helped me out
how much did you study before that?
A huge thanks for this amazing review video!👍 I've never left comments before, but I think it's time now. Also the best of luck to everyone watching!

Both educational and entertaining. Truly one of the best review videos of any topic I've seen. Thank you!
separate, integrate, celebrate. love it
I have an hour before the exam. Huge shoutout to whoever made 2x speed
This is actually the best review video I have ever seen
Very comprehensive and useful video... especially since the AP Physics C exam is tomorrow. :)
I learned more in this video than in the entire class
We really need an AP Physics C Mechanics review for 2021 updated from last year
Thanks man
You had me when you said “bamboozled”
i love you so much oh my gosh you are a godsend just stopped my one hour mental breakdown
🐐🐐
Oh my god this is the best video of all time ❤
watching this the day before the exam.
Really glad this popped up on my recommended the day before my college physics final
studying for this exam, video made me feel a lot betterabout it
Literally never comment but this video was the main reason I got a 5 if we had these for every subject easy 5s in all APs
This is very helpful! I can't tell how thankful i am bc i must hit the 5. Thank you so much!!!
this really is the ultimate review
Watching this an hour before the test 😁👍
dead serious i got a 5 because of this video

How much did u get??? Is it hard?? Mine is on 2 months n i havent prepared any 😢
got a 5@@Roddd2333
do you think i can clutch it up teach?
Thank you for this homie
Is there a sheet with everything covered in this video? I wanted to make sure I didn't miss anything while I took notes. Thank you!
No sorry. I just kinda drew slides and sent it. I should make one.
Hi David,
Thank you for all your videos.
Will you be making an AP Physics C Mechanics review for 2021?
Thank you.
i mess with this heavy
THIS IS GOATED THANK YOU
Thank you so so much!!!!
my guy's got smooth transitions
The ap exam in two weeks and lawd have mercy I’m screwed
Thank you so much for this. Helped me out a lot. thank you thank you so much.
Amazing video!
10:00 why is dL=dr? L is the length or the rod and r is the length from the point on the rod to the point.
r = l + D, but D is a constant so dr=dl
So nice thanks
THANK YOU!!
Just a quick note, at 25:14 I don’t think that is separable? I think you have to solve it using an integrating factor since it’s first order linear
It’s separable. You just need to keep the V-Q/C together and divide dQ by that whole term
Absolutely amazing! Thank you so much!
At 27:44 you said to point our pointer finger gun to our face but since the field shows that it’s into the page according to the circles with a dot in the middle of them, wouldn’t that mean that the force (middle finger) is to the left and not the right. Thanks for the amazing content by the way.
Edit: it was said around 27:38 ish sorry
Circle with dot means out of the page. Like the point of arrow coming at you.

Can you enable automatic translation please
David, I can't understand the E and Dr relation with V. I have never understood it, please make a video about it. I can't find it on Khan academy too
Yeah, good idea, I’ll see if I can make one.
@@WeAreShowboat Thank you
E = -dV/dr, dV = -E dr
To prove this, derive V with respect to r:
V = kQ/r = kQ * r^(-1)
dV/dr = (-1) kQ * r^(-2) = -kQ/(r^2)
-kQ/(r^2) is essentially just -E, given E = kQ/r^2
So from there, we have:
dV/dr = -E
dV = -E dr
I hope that was helpful!
Are you taking an Algebra or Calculus version of Physics? dy/dx or similar dV/dr means they are taking derivatives and is calculus-based
@@AgentJRock805 I have calculus based physics. I know it essentially means derivative. But I can't understand that relation intuitively. Like, Electric field is change in potential over distances?
