Because if someone asked you what a damping coefficient is, that equation is exactly what you would have to write down. The physics doesn't depend on what it's called, it depends on its quantitative definition and no more, which is exactly what I wrote down.

I did, because I wrote the definition of $\gamma$, which is a lot more than just the name.

I did, actually, in the 4th line: $v_t=F/\gamma$ (it's the damping coefficient).

Could you give me any references? Do remember that I am not talking about the ideal gas law here.

comment Do the properties of two streams flowing into an engine add together when they mix?
Extensive properties add, intensive properties average by weight of whatever physical quantity they are intensive in.

While I can of course write to you (because I know you), it would help if you laid out the answer more completely right here, in the spirit of this website. (This post is supposed to be helpful for anyone who thinks of this question and arrives here.)

@MichaelBrown, so essentially the object gets the energy from the atmosphere via drag? Where did the atmosphere get its motion from? The surface? All the way up to the top? And you see there needs to be constant feeding of energy to maintain this motion. Could you please elaborate a bit?
