Gravity is negative for example (-0.1)

AI Thread Summary
Negative gravity can refer to the direction of the gravitational force rather than its magnitude, which is always positive. Gravitational potential energy can be negative depending on the chosen coordinate system, particularly when the origin is set at infinity. The concept of negative gravity is often tied to specific interpretations of force direction and coordinate systems. While the magnitude of gravitational force cannot be negative, the perception of gravity as negative can arise from conventional sign choices. Understanding these nuances clarifies the discussion around the possibility of negative gravity.

is there a situation where the gravity is negative for example(-0.1)
and is it possible
i think it is impassible but i have a Friend who believe it is possible
so is it possible ? :smile:

What do you mean by "gravity" being negative? If you mean the force of gravity, yes it can be negative if it is pulling in whatever you define as the negative direction.

If you mean gravitational potential energy, then yes, that too can also be negative if you place the origin of your coordinate system out at infinity.

If you mean just the magnitude of the gravitational force, then no, this can't be negative by definition.
 
What do you mean by gravity being negative? In a sense, the force is negative almost everywhere, but that's because our traditional choice of coordinate system and sign convention makes it such.

Thread 'Question about pressure of a liquid'

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...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

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...
