why the x is not negative like too?

Now I understand.

people keep saying this is a good video but it didn’t explain anything to do with the Khan Academy test on de Broglie Wavelength at all

And after 7 years... (currently 2024), this video is still easier to understand than spending hours at lectures😂🎉

I have an exam in 4 hours, 😅 and this video made about 50 pages slide irrelevant 🎉😂

Does it also depends on the length of the spring

It’s slope gives velocity or displacement

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

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 KZfaq 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

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
