Doug,

I had to respond once again to your "UP" question. When you sit on a
Kitchen Chair you create a downward force the chair creates a "UP" force
equal to your down force.


Sure.
Not equal in all cases though, otherwise chairs would never
tip over or break, nyet?

Doug, does the chair move up? Of course not.

Because you created the down force first.

... Does it create LIFT? Damn
right it does and in a "UP" direction.


But if it had wings, it would go faster.

Actually there is a difference between "upward force" and
lift. You can throw a brick into the air, is that creating
lift? I thought that by asking about 'lift' and 'up'
together in the same sentence, it would be fairly clear what
I meant. Maybe not.
