If you read carefully, the premise of what they are saying is that, if
you have, for example, a sealed jar with air in it, you are permitted
to consider the air on the _inside_ of the jar, pushing up on the lid
as contributing to a force to lift the jar off the ground, but you are
not allowed to consider the air on the _inside_ of the jar, pushing
down on the jar un the upper surface of the bottom of the jar.
The atmosphere is not a sealed jar. The source of air pressure in the
atmosphere is gravity, not confinement and kinetic energy.
I feel as though I am in the presence of
genius.....


Take a tums, it'll get better

I'd prefer 2 touch-and-go's and a full
stop. I think that will clear my head.
