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 ?
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.
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
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
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... ♥️🥺
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!
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
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
@@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.
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!!!
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)
This is a really really amazing video, Khan Academy deserves all the subscribers in the world!
Sir u have a really good voice
It's so soothing that it makes our study more easy
This vid was uploaded on my birthday
happy belated bday
So what!?
Then what can I do
Happy bday.
Thats for P C
Thank you sir..i had somany doubt about floation..but everything is clear now...
This is such a great way of explaining woow!!

Excellence is something you have to be born with, this man proves it.
Wrong. Excellence is achieved, not given.
OMG! Such a clear explanation.. Thank you soo much sir! May god bless you
Wonderful explanation .... thanks
Superb superb.....exceptionally...good.....
incredible .... amazing
One of the best videos in this topics... Thank you !!
Really amazing explanation... It surely helped me to get out of my doubt... Thank u so much 🎉🎉
keep it up 👏👏👏 nice explanation 👌👌
Superb!!!!!!!

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

Sir you explained very well the concept of buoyancy and density, Thankyou sir Mahesh!
thank you very much, this vid really helps me a lot. your explanation is very clear. :)))
Very well explained
Way of your explaining is very good.
You way of explaining is soo much good ❤
You are awesome explainer!
Really great video informative thanks😊
Amazing explanation
Awsome explanation 🎉
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
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
Bravo to you sir 👍
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
Not weight of object..
Weight of the fluid displaced by the submerged object
@@faizfarhan8231 yes 👍 🙌
i love your presention
what about safety pin
For the last q - liquid = object
So basically if I put it on top it will float?
Thank you so much❤
Sir, I want all your videos on RUclips. Is there any playlist of all?. If yes, please help me by providing the link.
Thx👍
Much needed video.....❤️
Bad Video😠👿💢⁉
Can you prove that weight isn't decide to object will be sink or swim
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
Thanku so much 🙂🙂 This video helped me a lot 😃
What if the object has same density as of the liquid
It will float
It will stay where you leave it
@Hariom Shree yes with the whole of it inside water it will stay where you leave it
If you pushed it lower would it stay at the new location or does it rise to the surface ?
@@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.
How do we know how deep will an object sinks?
It will sink till the bottom.
Much great explanation
I have a question
What will happen if the weight of the body W is equal to the buoyant force Fb
What will happen when both water and object have same density
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!!!
Ship will partially float and partially sink
@@man07imperfext This is true ; I agree
Thanks❤
This saves my brain cells tysmm 😢😢
Ha ha
Thanks
It's really helpful thank you
Excellent explanation 👌
great video damnn
Thankyou sir
Very nice video.
Thankyou a lot of much ....
it also depend on volume
Superb
nice explanation
amazing
don't you have to account the viscous drag pushing in the same way that the upthrust???
If upthrust is more than the weight of gold what happens
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)
Thx
sir if the density of object put is same as liquid what will
happen? sir pls ans?
That object would be RIGHT UNDER the water
the object floats
It will Float
🎉🎉🎉🎉🎉
It's depend upon surface area
No it actually depends on the volume and mass
Omg it finally clicked
We never calculate density. It's a property of material. So please correct your words in the end of the video.
please Myanmar subtitles show me
Noobda
U tooo cus u cant explain like him u non
You can't get it that's why you are abusing.
why the hell do I think the narrator's voice matches with that of the narrator of FloatHeadPhysics
Excellent explanation
Nice explanation
