Buoyancy and Archimedes’ Principle: An Explanation

This video explains the buoyant force and archimedes’principle. I will also show you how to derive the equations for the buoyant force and archimedes’ principle. This is a very important principle in physics for object that float and sink in a fluid.

You are very welcome, glad you liked it!

[@user-dy6im4ng4t]

Thanks man it just simple and summarize a long video lecture that has been given by my lecturer. Hope my lecturer watches it aswell👍👍🙏🙏

[@stepbystepscience]

Glad it helped!

perfect explanation

[@stepbystepscience]

Thanks, glad you think so!

Sir, I have question, this different in pressure in liquid is cause by gravity so we can say gravity cause bouyacy?

[@stepbystepscience]

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.

[@mohamedadnan3345]

@@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

[@stepbystepscience]

@@mohamedadnan3345 But the Earth is not flat.

[@-tweeomoz-1786]

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?

[@stepbystepscience]

That is not relevant to the video.

[@Relatablename]

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.

[@georgegautam]

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

[@stepbystepscience]

OK

[@GelilaMulugeta-e9u]

Tnx God bless you

[@stepbystepscience]

Thank you too

[@GelilaMulugeta-e9u]

Tnx fr 😊😊😊😊😊😊

[@stepbystepscience]

Welcome

[@amywright4139]

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.

[@stepbystepscience]

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?

[@Yankee4ever2]

amazing

[@stepbystepscience]

Thanks, glad you think so!

[@jorgesoberon6866]

So, if our object is a flat sheet of metal, with h2=h1, what happens?

[@stepbystepscience]

That is not possible, everything has some thickness.

[@rezikotrikadze1697]

In that case the volume and mass would be equal to zero

[@SikelelaDamane]

TO YOUR DENSITY WHERE DO YOU GET THAT 1026KG/M^3

[@stepbystepscience]

I looked it up online.

[@AyAb-kx4ih]

Hi I am very interested in your work
