Archimedes principle & buoyancy | fluids | Physics | Khan Academy

[@adityapatil2374]

this is one of the best explanations ive ever seen

[@jananibaskar6936]

Such a great explanation...Thank you so much for giving the clarity of Archimedes Principle

[@priyankadey8489]

Did not know this topic was this easy before watching this vdo , thanks a lot 👍👍

[@batman-ekbramhachaari6820]

Thjs might be the greatest khan academy video i have ever seen 😮

[@Hino_55]

GREAT EXPLANATION ;)

[@anvaywahal737]

Hulk said "Eureka!!!!!!"....great video

[@PranavKumar-dd2xo]

This deserves millions of views

[@kingsurya3215]

I have never seen someone teaching it so subtly, all my query is resolved, I have been really puzzled about .when I don't get answer, I start getting upset it's become very difficult to live with a question in mind ....thanks u

[@confidenceadjokatse5864]

Thank you very much sir for the powerful tutoring on the archimedes principle

Mind blowing Helped a lot Thanku so much sir

9:13 just because your lungs might expand, doesn't necessarily mean you will increase likelihood of becoming buoyant. imagine if the lungs were filled with concrete instead. Thus, the expansion of volume does not cause buoyancy per se, nor is it the "displacement of liquid" that causes buoyancy. Buoyancy is dependent on density of materials.

[@Technoblade_never_dies_1]

No, the buoyant force will remain the same. What changes when the density is increased is more mass thus more gravitational force and that pulls us down. So you will not drown because the buoyant force is less, you will drown because your weight is *more* than the buoyant force. Buoyant force is independent of the density of the object.

[@mridulboro7467]

Amazing explanation. Understood easily sir. Thank you so much😊

[@gitaglobalschool3218]

The time at present is 11:38 am and at 1:45 pm my science final exam will start in school for which I will depart at around 1 pm. My 9th grade whole biology + gravitation is left and now I am wasting my time writing this comment

It helped my son so much😁

superb explanation. Thank you very much for your fantastic lecture. Subscribing your channel, I recommended my kids to watch and learn from you.Thanks from SriLanka

You’re Amazing!✨

[@hafinessevoice2311]

Thank you! Thank you. Thank you for this wonderful explanation! You teach with ease and your explanation is practically a "bombshell!" 👌🔥🔥so to speak.

[@akabane_karma]

Sir, you explained why pressure increases as we go down in a liquid (in the previous video)... You said it was due to the fact that the weight of the upper part of the water pushes down while to balance out the weight the lower part applies greater force than the upper. My question is- why the bouyant force remains same even if u put a higher density metal? Doesn't the metal also put weight in the lower part of the water ?

[@aryan1389]

Absolutely fantastic lecture blyaaad!!!

Thank you sooooooooo soooo sooo sooooo muchhhhhhhhhhhhhhhhhhhhh

Thank you veryy muchhhh

[@shumailamalik6225]

You are just amazing!

[@predatorgaming895]

Great explaination🔥

[@Diya.Dasari]

thank you sir

[@YouNeedAFriendLikeMe]

I have a doubt. The buoyant force is the weight of the displaced fluid, and in theory the more the weight of the submerged object, the more the force right? Then why do heavy objects sink? They should stay afloat right? And all the non heavy object should sink bit they float? Why is that?

[@cagasmarkrommel3436]

Thanks

[@Naina_mohanty]

Great explanation..It helped me a lot.🙂

[@meghasharma7746]

"BEST"🙏

[@ShivamAttargekar-ot3tf]

Best but archimedes wore shirt too

[@inderveersinghsount9017]

Density of common salt is more than density of water . Then why sodium chloride dissolve in it??

[@ujaanroy3075]

The formula of pressure is h*rho*g where rho is density. This tells us that pressure depends on the material that is submerged. But you said it does not matter what material we put in the water, the buoyant force remains the same. Why?

[@ut6582]

Hey Dumb dumb rho is the density of the liquid, not the object being submerged. Use thy brain. (

[@worldofmusic1058]

@@ut6582 He said the same. Density depends upon the material, or more specifically, the compound or element which have different density. I too have that doubt.

[@nkaurum3482]

@@worldofmusic1058 rho here means the density of the fluid and not the density of the object

[@beingtohuman]

Doesn't buoyant force differ in accordance with density of various materials?

[@predatorgaming895]

Bouyant force depends on volume..... If mass is more then it sinks... If mass is less then it floats ..

[@rscorT101]

OP EXPLANATION

[@wise_old_tree]

Legit god

[@manasviii7960]

okay doubt- why do ships sink sometimes....the same amt of buoyant force is acting on it right??

[@harshvardhanmankotia6492]

Water fills in

[@oliviadegonia2788]

ships will sink usually when water fills the space..this would increase the mass while the volume stays the same and will increase the density so that the it’s greater than the water. this will then cause the boat to sink :)

[@veenaraghavendra8574]

Will the upthrust be same on an object when it is submerged in liquids of different densities? Kindly explain this

[@BongelaMnguni]

A denser (heavy) liquid will cause a more Buoyant on the same object if it were submerged on a less denser liquid. Example: suppose I have two liquids Water (density = 1000 kg/m3) Air (density = 1 kg/m3) Then I submerge an object with a volume = 1 m3 in both liquids. Note that: weight of submerged liquid (buoyant) = density of liquid × volume displaced by object on that liquid So in water: Buoyant = 1000 kg/m3 x 1 m3 = 1000 kg In air: Buoyant = 1 kg/m3 x 1 m3 = 1 kg So you see that the same object experiences 1000 kg of buoyant in water and 1 kg in air

[@DevRSingh]

Hye sir, is FloatHead Physics also yours???

[@gk2853]

Yes, its his

[@kidskudos4775]

I have a doubt

[@gdftech3401]

then why a wooden block floats n water Hope u read my comment

[@mainangatia2039]

The density of wood is less than that of water so the density of the water it will displace will be greater than that of the wood. According to the formula buoyancy = weight of displaced fluid so if the displaced fluid weighs more than the wood it generates a greater buoyant force thus the flotation. I really hope I've helped. Physics isn't my thing but I really wanted to help.

[@Aalijah_Matyevna]

@@mainangatia2039 Why is the density of water more than wood?

[@bikobiko]

@@Aalijah_Matyevna wood is more hollow than water. Depends on what kind of wood though
