[@amood76]

I can't express how grateful I am. I feel like crying

[@amood76]

My lifesaver. I owe you

[@INTEGRALPHYSICS]

There is no crying in physics...

[@adhishpv6315]

The video was really helpful, If you have any reference for this video can you share it please? Thank you

[@Klockarbo]

Stupid question, but how do you calculate h = 0,3? Thanks for the video!

[@INTEGRALPHYSICS]

Did I lose you in the algebra? Let me know, I'm happy to help.

[@USVROTOENGINEERS]

Sir, This video is very useful for designing a floater. Thank you

[@INTEGRALPHYSICS]

Glad it was helpful!

[@Gaming-vd3dv]

Thank you sir, but isn't there a force acting on the block from the pressure of the atmosphere so the force F =pA(area of the block)? Then the forces would be Fb = Fg + F(air?)?

[@INTEGRALPHYSICS]

Yes the atmosphere is acting downward on the top of the block. However it is also acting downward on the water, increasing the pressure in the water too. Ultimately it cancels out.

[@Gaming-vd3dv]

​@@INTEGRALPHYSICS That makes sense, thank you

[@GuidoHaverkort]

Is it fair to say that the 'depth to height of the block ratio' is the same as the 'density ratio'?

[@INTEGRALPHYSICS]

Yes.

[@USVROTOENGINEERS]

Sir, How finally have you arrived at 0.3M? Can you explain? Thanks

[@USVROTOENGINEERS]

I tried and got the answer, Thanks

[@SPARROW_GAMER.321]

You are a good teacher

[@INTEGRALPHYSICS]

Thanks!

[@murphygreen8484]

If the height were to come up higher than the object would that mean it would sink?

[@INTEGRALPHYSICS]

Yes. If the calculated h is greater than the actual height of the object, it means the object does not displace enough fluid to float (ie. The object is denser than the fluid in which it is immersed)

[@murphygreen8484]

@@INTEGRALPHYSICS thank you!

[@abinvarghese-g1j]

if the block made by mild steel then multiply by density of mild steel to get FW

[@danishh1385]

This question come out in my test and I forgot how to do it

[@ArjeeBhajee]

Thank you so much!

[@INTEGRALPHYSICS]

Glad it helped!

[@mmnyako]

Thanks for sharing!

[@INTEGRALPHYSICS]

You bet!

[@adilaitbaev5456]

Thanks!

[@INTEGRALPHYSICS]

No problem!

[@ahmadjauhar3204]

thank you so much, this is what i just need to bus

[@INTEGRALPHYSICS]

No problem!

[@unknown-gy8jz]

tq

[@INTEGRALPHYSICS]

You're welcome.

[@smiha7531]

Helped!

[@INTEGRALPHYSICS]

You're welcome! It was a fun video to do!

Since gravity is a buoyant force in a vector pointed at Earth, interesting math awaits to shed light on why 'buoyancy' of an object of matter FROM space TOWARDS Earth is never quenched (except by the blockage created by the surface of the planet). An object of matter that is in space, and is too far from any celestial body to exhibit any acceleration, is not buoyant. It is at rest in space. But if the matter object is brought near a celestial body, it gains an unquenchable buoyancy that is only 'arrested' by the planet's surface halting its buoyant acceleration. The conventional math describing this 'buoyancy' is F = mg and GPE (gravitational potential energy) = mgh. But with buoyancy of a matter object in water, we know the exact physical nature of the source of the buoyancy. The 'buoyancy' of matter objects accelerating toward a celestial body is also due to a pressure gradient, but it is an electromagnetic gradient created by the constituents of so-called 'empty' space. And that is the kicker - conventional belief is that space is empty, so there is no way to create a pressure differential. But there IS an acceleration gradient. The exact physical nature of the source of the acceleration gradient - is a worthy line of inquiry. .

Definately this knowledge was used in teh construction of teh pyramids some how.

[@hapless_152]

Good explanation, switch off the annoying music, ahrd to hear what you're saying.

[@INTEGRALPHYSICS]

Thanks for the suggestion. I stopped putting music in the videos for this very reason. Unfortunately its not something I can just turn off after uploading.
