Of course gravity is important but the buoyant force is the upward force a fluid exerts on an object. It comes from the fact that the pressure in a liquid increases with depth, therefore there is more force on the bottom of the object than there is at the top of the object.
@@stepbystepscience I know sir , but imean this increase in pressure when we go deep cause by gravity Right?, Because flat earther say there's no gravity just bouyacy and density
sir in neutral boyancy if you push the object down in water will is rise up to the middle or if you place it up it will be up but if you say sir that it will come back to middle if thats so then why can we call the forces equal
This is somewhat irrelevant but, because the definition of a fluid is an object that takes the shape of its container, could powders be considered liquid and does powder have buoyant properties?
Powders are still made up of quite large particles and they don't associate with each other significantly past electrostatic forces or contaminant surface tension. Liquids are their own discrete phase of matter.
In other sources, it shows that for a floating object the buoyant force and the gravitational force (weight) are balanced. Not one greater than the other as you show.
Good point, when the object is floating at the surface the buoyant force and the gravitational force are equal. But because it floats to the top of the water the buoyant force (when the object is completely under water) is greater than the force of gravity. Sorry for the confusion, does that help?

This is the simplest and yet explicit explanation I have gotten so far. Thanks for this video
You're very welcome!
Amazing explanation! Was looking online for a while, best explanation so far! THANK YOU SO MUCH!
Glad you found my video, thanks very much for your comment!
phenomenal explanation! Thank you very much for this video ❤
You're very welcome!
Hello Sir I have a question. Isn’t the upward force always buoyant force, so why do we subtract f2-f1?
Thanks man it just simple and summarize a long video lecture that has been given by my lecturer. Hope my lecturer watches it aswell👍👍🙏🙏
Glad it helped!
Very good explanation,enjoyed the revision.
Glad you enjoyed it! Thanks for your comment.
Your explanation helped me a lot..👍
Glad to hear that, best wishes.
Sir, I have question, this different in pressure in liquid is cause by gravity so we can say gravity cause bouyacy?

OK
thank you so much!! you helped me a lot!
Glad I could help! Thanks for watching
Nice simple explanation thank you

This is amazing thank you
Glad you think so and thanks for watching!
ty for the explanation
Thank you for watching!
perfect explanation
Thanks, glad you think so!
Tnx fr 😊😊😊😊😊😊
You are welcome.

So, if our object is a flat sheet of metal, with h2=h1, what happens?
That is not possible, everything has some thickness.
In that case the volume and mass would be equal to zero
Tnx God bless you
Thank you too
TO YOUR DENSITY WHERE DO YOU GET THAT 1026KG/M^3
I looked it up online.

Hi I am very interested in your work
Thanks for your interest and best wishes
F2 should equals the gravitational force + f1
amazing
Thanks so much!

Tnx fr 😊😊😊😊😊😊
Welcome
amazing
Thanks, glad you think so!
