Why airplanes taxi

Fixed-wing aircraft taxi because their wheels reduce friction as they
move forward
on the ground.

:-) I am feeling profound today...


They taxi because they want to get to the airport and catch a flight...

So, logically, spacecraft in the frictionless environment of outer space
should immediately accelerate to the speed of light.

No, it still takes energy to accelerate a mass, even in a frictionless
environment. However, it would not take energy to maintain velocity in
a friction free environment. However, space (especially near space) is
not frictionless.

It seems this discussion is heating up...

So, you thought that you should simply post a statement like that ...

Now, *see* what you've gone and done! :-)))

No, airplane's taxi because they can.

Or is it because they must?

The only thread better than this one was the one where the guy wanted
to get a uniform because he'd just gotten his PPL.

Phil, to support your theory, I can tell you the earth weighs 130
pounds in my gravitional field (that's before breakfast. It gains a
little after that.).


I have been noticing that the Earth is getting heavier and heavier as
the years go by. I think something needs to be done about this Global
Bloating.

The corollary to that would logically be that any object entering the
atmosphere from outer space would instantly decelerate to zero speed.

Only with infinite friction.

I'm just applying your flavor of logic.

I think the meaning of logic got slighty warped as Mx's spacecraft passed
the most recent black hole. ;-)

The statement that started this thread was fundamentally incorrect. *I've
illustrated why.

Nope. Show me a wheelless airplane taxiing. Skis don't count ;-)

How about floats though?

Has anyone considered the friction between floats and water?

What object could ever be accelerated to the speed of light?
