Sir u have a really good voice It's so soothing that it makes our study more easy

[@tanyapathak5690]

This is a really really amazing video, Khan Academy deserves all the subscribers in the world!

[@roselinedesiree5196]

This is such a great way of explaining woow!!

[@suvarnak2880]

Thank you sir..i had somany doubt about floation..but everything is clear now...

[@chikengas4052]

This vid was uploaded on my birthday

[@arkorakshit8872]

happy belated bday

[@PC-ty1zt]

So what!?

[@shreesingh9343]

Then what can I do

[@adalbertangulo1521]

Happy bday.

[@adalbertangulo1521]

Thats for P C

[@cillianMurphy67]

OMG! Such a clear explanation.. Thank you soo much sir! May god bless you

Excellence is something you have to be born with, this man proves it.

[@mamatarout3278]

Wrong. Excellence is achieved, not given.

[@swapanmallik983]

an object floats on water whe the buoyant force is equal to the weight of the object but many have a misconception that an object floats when buoyant force is greater than the weight of the object(by the whay which is quiet not wrong to say) *here is an Explaination to this statement*:- when buoyant force acts constantly upards then the object must acclerate all the way up at the surface of the fluid. but when the object reaches the surface of the fluid the magnitude of buoyant force becomes equal to the magnitude of the weight of the object. therefore the object does not further accelerate upward and rests on the surface of the fluid that is the object is now in a state of equilibrium

[@aditimitra8040]

I had a question. If we had the gold chain in the first example partially immersed in water, in such a case when we say weight acting downwards, do we mean the weight of the immersed part of the solid or the whole solid ?

[@xrdarken-raj4073]

It means that the portion of chain which is immersed in the liquid(which we call simply the displaced liquid)that portion of the liquid weighs equal to whole weight of the chain.

[@tanishqsinghal2082]

Wonderful explanation .... thanks

[@zishaviswas477]

Finnallyyyyy... Finnallyyyyy I got my doubt solved.. thanks for the logical things.. I think without logic physics is not physics.. you gotta feel it but generally everyone try to explain in in mathematical language... You finally solved my problem

[@nazimazafreen6203]

It's very helpful to understand Thank you very much 😇😇😇

[@priyankapandey9934]

Really amazing explanation... It surely helped me to get out of my doubt... Thank u so much 🎉🎉

[@Hino_55]

Density of the object must be smaller than the density of water for it to float. Sir you explained very well the concept of buoyancy and density, Thankyou sir Mahesh!

[@lordrishi_76]

Thank u very much Khan Academy... I searched a lot on youtube for this explanation but I didn't get one..... And finally I got one of yours..... And I am really grateful... Thanks a lot... ♥️🥺

[@arianaazmir4321]

thank you very much, this vid really helps me a lot. your explanation is very clear. :)))

[@bharatchauhan846]

Very well explained

Way of your explaining is very good.

[@gaganjeet12345]

Superb!!!!!!!

[@cookie-nzl8940]

If we used an object with the same density force as water, how does the object act? Eg. Could a human push it lower and have the object stationary there, or would it always raise to the surface

[@eifabeeekhan4571]

no it wont rise up as bouyant force is same as that of weight of obj , so it will remain at the same place where you left

[@aminaafzal374]

incredible .... amazing

[@Hamnaaz-h8n]

Really great video informative thanks😊

[@dranuragkumar-q2g]

keep it up 👏👏👏 nice explanation 👌👌

[@MB_2003_Hello]

You are awesome explainer!

[@TS-vh9rs]

Does partially submerged and floating has a difference I'm confused cuz Archimedes priciple says upthrust of a partially submerged object= weight of the liquid displaced but law of flotation says upthrst =weight of the object

[@faizfarhan8231]

Not weight of object.. Weight of the fluid displaced by the submerged object

[@deepeshsachan5664]

@@faizfarhan8231 yes 👍 🙌

[@kidsprogramming8220]

i love your presention

[@zaen3220]

What if the overall density of the ship is larger than water, and it manages to displace a mass of fluid heavier than its own mass using blades and machinery!!!

[@man07imperfext]

Ship will partially float and partially sink

[@yanzhuye7851]

@@man07imperfext This is true ; I agree

Bravo to you sir 👍

[@TharuJayayawardhana]

Thank you so much❤

[@ghulamsabir7167]

Can you prove that weight isn't decide to object will be sink or swim

[@Harsh-hl2ek]

Yes as the fish and a good Human swimmer both can swim or the iron nail and whole iron ship so it depend upon its density

[@Piyushx122]

Much needed video.....❤️

[@yanzhuye7851]

Bad Video😠👿💢⁉

[@gamer_random2511]

For the last q - liquid = object So basically if I put it on top it will float?

[@spacepotato672]

Thx👍

[@AshrafAli-qn3gb]

It's really helpful thank you

[@RockySharma-j8h]

I have a question What will happen if the weight of the body W is equal to the buoyant force Fb

Sir, I want all your videos on KZbin. Is there any playlist of all?. If yes, please help me by providing the link.

Excellent explanation 👌

[@natureinitsbest6551]

Thanks❤

[@ayaanlohia7443]

What if the object has same density as of the liquid

[@rnhuntergamer2117]

It will float

[@palak6981]

It will stay where you leave it

[@palak6981]

@Hariom Shree yes with the whole of it inside water it will stay where you leave it

[@cookie-nzl8940]

If you pushed it lower would it stay at the new location or does it rise to the surface ?

[@vinayaksinghparihar1971]

@@cookie-nzl8940 it will always float on water if you push or pull it. Till the force applied externally acts it will not float but as soon as it withdraws it will come back to surface.

[@VISHALKUMAR-oo2rf]

What will happen when both water and object have same density

[@kiransaleem9856]

it also depend on volume

Thankyou sir

Thankyou a lot of much ....

[@cagasmarkrommel3436]

[@sonjaku41]

don't you have to account the viscous drag pushing in the same way that the upthrust???

[@readerzclub9211]

Very nice video.

[@rubentuting525]

How do we know how deep will an object sinks?

[@Fletcher_163]

It will sink till the bottom.

We never calculate density. It's a property of material. So please correct your words in the end of the video.

[@akhilt2405]

Superb

[@raviprakash375]

It's depend upon surface area

[@yajats8675]

No it actually depends on the volume and mass

[@DHANUSHS-yj8ez]

what about safety pin

[@ChampionsJourney_7]

If upthrust is more than the weight of gold what happens

[@Vabadrish]

Suppose you leave the object which is supposed to float ( buoyant force is greater than weight of object) under the water There upward (buoyant) force is greater than downward(weight) force As soon as you leave the object, it will accelerate upwards and will jump out of the water level becoz of acquired velocity (Practically , becoz of surface tension,air drag final result might differ but let's keep it simple for you to understand)

[@james_louis2803]

sir if the density of object put is same as liquid what will happen? sir pls ans?

[@yajats8675]

That object would be RIGHT UNDER the water

[@Your_Father_]

the object floats
