systum 🔥🔥
what if its not water , what if its a concrete floor
Fantastic explanation!
walter is my goat
thank you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! you can't imagine how grateful I am!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
very good lesson
Best explaination !
Thank u bro
Your sacrifices don't go unnoticed. ... You made this easy to understand. .💜 BEST TEACHER 💜💜🐰 Finally i understood😂
I look away for one second to work on a lab, and the shoe is sideways talking about 3 other axis hahahah.
Anyone here in 2024
Please position of velocity time graph
2:43 heres come my boy... None other than... LUI DE BROY
This is the creepiest comments section for a video i've ever seen
Khan Academy is also nice for math practice as many know.
Consider electron wave and positron wave are the same but out of phase. So there is only one charge that can either be constructive, same charge, or destructive, different charge.... more to follow.

Sal Khan deez nuts
Can you explain me thermal energy?
test in 9 hours, no worries
at 10:39 aren't both force vectors still counter clockwise??? I think im stupid
im stupid nvm
How is sal
What if the ball was sticky and stuck to the rod?
Sir this is what I was searching for days.... Thank you so much ❤
excellent
I’ve been searching all over RUclips for a good playlist to explain oscillations and this is genuinely the only video that has explained everything so well and made it crystal clear for me. Thankyou very much for uploading this
ikr! khan academy is dope
Thanks =]
I'm sorry, what were you saying?
Can you please make a video on circular motion at constant speed
Thank you so much for this! 😭 my school doesn't do lectures but instead just give us notes. This topic, they didn't really elaborate about this one and tomorrow is our exam, FINAL EXAM. 😭. Now I understand everything about this now 😭
Thanks sir am watching from Uganda,,,,yov made me understand more
Thank you so much Khan Academy
Hey, small question,.. why does adding phase imply the wave is going to the left?? And for a sin wave starting going up above the x axis, is the equation asin(wt-kx) or asin(kx-wt)????
Hands down the best video about elastic collisions!!!
awsome
Thank you so much for the video! I was really confused about this topic.
I really appreciate this video; I have an AP physics 1 final tomorrow and I needed a refresh on angular momentum. This video was perfect!
wish u were my physics teacher....lecture wouldn't be that boring
can i give you a kiss on the cheek
khan academy i love you
THANK YOU
Thank you
This is cool
Even a 10 th class student can understand this very properly explained thank you sir😊
why is the distance squared?
طالب سادس زيروغيمس جلقم بلكم بلمم
As USAFA cadet currently on Academic Probation, thank you
amazing explaination
This guy is great merde
understood nothing out of my textbook intuitively but now i clearly understood this
