Would an hourglass on a rocket going up empty faster than one on the ground?

AI Thread Summary
An hourglass on a rocket accelerating upward would likely empty faster than one on the ground due to the effects of vertical acceleration. The discussion centers on understanding the mechanics behind why the sand falls more quickly in an accelerating frame. It is suggested that the downward force on the sand above the neck is not the primary reason for this increased speed. The participants are exploring the relationship between acceleration and the gravitational forces acting on the sand. Overall, the inquiry seeks to clarify the physics of how acceleration influences the flow of sand in an hourglass.

Just wondering. Would appreciate any input! :)

What do you think? :P
 
I think that if the rocket was accelerating then the hourglass would indeed empty faster. I'm trying to figure out why, though...
 
If the hourglass does empty faster it is not due in much part to the downward force on the sand above the neck.

Well, what makes the sand fall in the first place? What effect would vertical acceleration have on this cause?
 
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...
