Air resistance and Gs?

Question

If there is a small peice of metal (microscopic) that is in closed cilindar (which has regular air in it, or if you would like, some common gas) which is shaped almost exactly to the same shape as the peice of metal, how much will (standard earth) gravity effect the position of this metal? Is there some formula to calculate such things if density, volume, and changing Gs (force) are included? If the metal is fit exactly (or as exactly as posible) to the shape of the cilindar, is it POSSIBLE for the metal to move? Again, any formulas for how much force would be required to move said peice of metal?

If anyone includes any formulas, detailed explentations are appreciated.

Answer 1

Not sure I really understand what you are getting at...

Gravity will effect the object in the same way as if it were not in the cylinder. Gravity passed through objects, including the container.

Microscopic objects in a liquid may become suspended if they are small enough. In this case buoyancy is counteracting gravity.

hope this helps.

Answer 2

if you mean by not touching it and it moving the formula for the common gas is

P.V=n.R.T

if V changes it means that the cilindar is moving

P(Pressue) V(Volume) n(# of mols of the gas)

R(the regular numbr 8.314) T(Temperature)
