Center of gravity vs center of mass

AI Thread Summary
The center of gravity and the center of mass are distinct concepts in physics. The center of mass refers to the average position of mass in a body, while the center of gravity is the point where the total weight of the body is considered to act. In uniform gravitational fields, these two points coincide, but they can differ in non-uniform fields. The discussion highlights the importance of understanding these differences for accurate applications in physics. Clarifying these terms is essential for proper analysis in mechanics.

Is it different from the center of mass? My book says yes but doesn't answer the question.

Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
