    Capillary Rise
Click For Summary
In a zero-gravity environment, the capillary rise effect is significantly altered due to the absence of buoyancy. Fluids may not remain confined within containers if they do not wet the walls, potentially leading to fluid expulsion. This phenomenon also affects porous media, such as soil or hydroponic systems, where water transport to plant roots becomes unpredictable. Additionally, in systems with porous barriers, fluids may require higher pressure to pass through, complicating fluid dynamics in space. Overall, the removal of gravity introduces complex challenges for fluid behavior in capillary systems.

Apparently that happens.

Taking away gravity (more precisely, removing buoyancy effects) can cause all kinds of interesting behavior. It's possible that the fluid will not remained confined within a container- if the fluid does not wet the container walls, the fluid may be driven out of the container.

It's also a problem for porous media- a specific application is soil/hydroponic media- the fluid surface is not uniquely defined, and so water may not get transported to the roots of a plant. If there is a porous filter barrier in a fuel or water line, the fluid may not pass through unless there is sufficient pressure to drive it.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
