Anthony Harburn - Earth Shape Deception.. Flat. I Think.. pressure density and buoyancy... not gravity..
Dear Anthony Harburn,
Fact check = You FAIL
There is NOTHING in the Dr. Carlson physics video that says anything about gravity.
So why do you say - not gravity?'
What is pressure?
the continuous physical force exerted on or against an object by something in contact with it.
The Earths atmospheric pressure at sea level is 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch.
What is density?
the degree of compactness of a substance.
The density of water is 1 g/cm3
The density of lead is 11.34 g/cm3
What is buoyancy?
the ability or tendency to float in water or air or some other fluid.
What is gravity?
the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
As you can see from the above definitions, gravity is not the same thing as pressure, density or buoyancy.
Density is not weight or buoyancy:
Weight: If density alone was weight, then ALL objects would fall at different speeds on the Earth. Dense objects would fall faster than less compact objects, even if they weighed the same. But that is not our experience. Everything on Earth falls at 9.8 m/sec/sec acceleration.
So that assertion is WRONG.
Buoyancy: In space all objects float the same - light or heavy, dense or less solidity, astronaut or microphone.
So that assertion is WRONG.
