This is such a great way of explaining woow!!
Sir u have a really good voice It's so soothing that it makes our study more easy
Thank you sir..i had somany doubt about floation..but everything is clear now...
OMG! Such a clear explanation.. Thank you soo much sir! May god bless you
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.
thank you very much, this vid really helps me a lot. your explanation is very clear. :)))
It's very helpful to understand Thank you very much 😇😇😇

Wonderful explanation .... thanks
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... ♥️🥺
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
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
Superb superb.....exceptionally...good.....
You way of explaining is soo much good ❤
Superb!!!!!!!
incredible .... amazing
Very well explained
It's really helpful thank you
You are awesome explainer!
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!
Really great video informative thanks😊
i love your presention
Bravo to you sir 👍
Way of your explaining is very good.
Amazing explanation
Excellent explanation 👌
Much great explanation
Thankyou a lot of much ....
Thanku so much 🙂🙂 This video helped me a lot 😃
Sir, I want all your videos on KZread. Is there any playlist of all?. If yes, please help me by providing the link.
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

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
I have a question What will happen if the weight of the body W is equal to the buoyant force Fb
Much needed video.....❤️

For the last q - liquid = object So basically if I put it on top it will float?
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
nice explanation
Nice explanation
Superb
amazing
don't you have to account the viscous drag pushing in the same way that the upthrust???
Thanks❤
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!!!

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