Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

[@Mustafeinaxaamud]

thank you very much you explained it very simple and understandable way

[@kblim7753]

How wld sound changes when it travel from air to water ? Eg. Can the fish in an aquarium hear the sound from the TV next to the tank ?

[@deepakmishra5223]

Thank you.
One thing I arrived here was.
If speed of sound waves is inversely proportional to density then.
Why solid have much higher speed sound then water.
As water have lower density ..
Stiffness is main concern ..thank you thank you

[@obaidurrahmansaikh4899]

Spee of sound is also related with temperature
If temperature increases, sos increases

[@LimeLivesMatter]

I came here to learn the complex demonstration of sound because of Zebra from Toriko. Thanks, this helped me

[@dhavalshah3881]

This is absolutely perfect. Such a clear and logical explanation!!!

[@muhammadm4582]

My intuition says, velocity of sound is proportional to density

[@ankitasolanki2144]

Short and crisp ..... really helped!🙏

[@andrefranco6814]

Just spot on, thank you for sharing :)

[@kunaljha6856]

Thank you, for making this concept more clear

[@SubhamMeher]

Exectly what i was looking for

[@StudiousSeanReads]

Just curious as to the explanation of why the speed of sound is usually faster in solids >> liquids >> gaseous mediums, and how changing temperature, density, affects the speed at which sound travels through the media?

[@victormaxwellpeters9771]

When air is concerned, if we heat the air then spacing between molecule increases hence speed of sound should decrease actually

[@sarahkelly3619]

Victor Maxwell Peters true however, in gases, an increase in temperature causes molecules to move faster

[@palak6981]

Thank you very much for this awesome video!!

[@alpik09081996]

Really really amazing vid bro👍🏻

[@illujana2317]

Amazing 😗😗😍...cant be more grateful for this chanel.

[@sangramjena9173]

good explanation. thank you sir

[@WSCOMPUTER]

Another great movie!

[@jvillalobos6988]

thank you for clarifying this tho. I could explain why.

[@emilygreen2436]

amazing video. thank you.

[@jaweriasiddiqui2193]

wonderful. thanks alot.

[@rhythmic2103]

thank you

[@divyabhatia6018]

This can also be understood by putting your one ear on a metallic sheet and doing the same process. You will hear sound earlier from the ear placed on table than in air.

[@dortartakovsky7123]

the Formula of B/p(root) is applied only for liquids.. for gas we use different formula

[@sarahkelly3619]

Thought sound travelled faster through denser mediums?

[@Ysr1991]

what is effect of viscosity of water on speed of ultrasound flowing through moving water

[@lspellslogic877]

Thanks for the lesson. Im only here for my exam later anyway cuz i forget stuff when i read since theres nobody there and only a book ._. Idk why but i like to learn while talking

[@KandidlyKristenlove]

Does the Khan Academy make printable slide shows of their AP physic videos?

[@niladrisaha3039]

Sir I've doubt regarding the difference in dry air and moist air..... what's the exact difference between them and how come the speed is faster in dry air than moist air?

[@BilalKhan-yx2wq]

Quite helpful
Thanks

[@_p_r_a_j_w_a_l_2_1_11]

Thanks bro it helped me a lot for my work sheet

[@meriton87]

You are doing a great job. Keep up the pace and good work. God bless you!

[@STOJANNOVIC]

I am from Serbian and i was searching for an answer to why is sound slower in denser gases ... so thank you !

[@mr.unknown5577]

Nice explanation 👌

[@kaidenmajarali7665]

This makes sense, when my professor told me the velocity of sound in air is 1130 ft / sec, the velocity of sound in water is 4,800 ft / sec, and the velocity in solids is about 18,000 ft / sec. I didn't understand how that was possible.

[@shadmanshakib5568]

God i love this guy❤

[@justindougherty5265]

If force travels at certain speeds how fast does it travel in air when an SR-71 is going mach 2. Shouldn't it be impossible to go faster than force is transmitted

[@sriluveera]

Thank you sir .It was very helpful.

[@info-hub457]

i read somewhere that When the medium is dense, the molecules in the medium are closely packed, which means that the sound travels faster. Therefore, the speed of sound increases as the density of the medium increases.
is this true?

[@dabajithsushill9445]

Nice explanation.

[@d1mple381]

not everyone has a railroad track in their homes

[@muskaanseher4144]

amazzziiinnngggg

[@yogendersingh3588]

Awesome

[@nickmahramus5034]

so why does water travel faster in water than in air if the density is inversely related to the speed of sound?

[@nickmahramus5034]

typo. why does sound travel faster in water*

[@JazziHD]

+ khanacademymedicine you give an amazing explanation i understand everything you said well done:)

[@vinathikambham5985]

Thank u so much edunovus.i understood the vedios with out any doubt.before this I was struggling a lot.but after watching this I became perfect.

[@stelarieves]

Thank you!❤️

[@natanelabay2782]

Itis so nic i love it

[@tombouie]

Well-Done

[@71sephiroth]

awesome! but why square root of B/ro?

[@71sephiroth]

thanks!

[@fernandohood5542]

Should gravity be in that equation?

[@malslrrb]

for everyone who just want the answer 2:34
yw!

[@HumaNHamna]

Wow! This video is SPOT ON! A big thumbs up :)

[@shreyasaha199]

I WAS SO PERPLEXED WITH THIS TOPIC .............TYSM.

[@akilaathava3647]

Best

[@mr.heisenberg5119]

Speed of sound in air??

[@Aryanmetha13]

I still don't get how why increasing density makes sound slow?

[@rubiumar246]

Are you a khan?

[@starkrafter1977]

but what about ice because its 0 degrees and also a solid

[@savageutkrist1452]

0:59 is very dull sound

[@Palladiumavoid]

Imagine decreasing speed of sound so much that it travels 1 kmh

[@AKB95]

Thank you so much. LOL!! Don't try this at home...

[@laxikabisht6209]

U ARE WRoNG
