OK the atmosphere by definition envelopes the earth.The force keeping it here is solely gravity.
The "force" opposing this is diffusion across a pressure gradient into the vacuum of space.
Assuming that is correct how could I prove this other than looking out the window.
Newton's law of gravity will give the force Earth exerts on a single molecule, the force of the vacuum??
