Re: [Phys-l] Finishing up with that Dead Horse.



Buoyancy is absolutely, positively, no question about it, 100% sure, always, and forever more NOT about "loss of water."

Let''s keep it ridiculously simple.
Is the 'Buoyant Force' 'caused' by the loss of the water or by the
collisions of water molecules that MUST be under the cube in order
for buoyancy to occur?

Everybody got their answers ready??

Careful Hugh - I'm specifically stating that the water container is

Some water WILL flow out of the system.

When before the cube is lowered into the tank or after?

If before, why bother. Why not just save the extra calculation and
fill it enough so that it will cover the cube without letting the
cube touch bottom. Makes the calculation easier and doesn't change
the physics.
