Artificial Gravity Problem

No, it was wrong on both accounts.

>"And air resistance can't push you down."

False. Air resistance is a reaction force that is applicable to jutting normals.

>"Its a force that works in the opposite direction of your velocity."

False. It is a component of surface tension, and reaction force. These components do not have to be symmetrical.

>"Air resistance is negligible for such massive objects at low velocity."

Irrelevant. There are no counter forces applicable.



You can find the option on the 'functions' section of the right hand panel.

Just to point out, air resistance can only occur if the air is resisting. Have we established the direction of flow for the air in relation to the vehicle and the docking port surface?

It is true in these circumstances. They are vehicles and not idealised objects.
How specific do you want me to get ?
Your statement is correct if it's a flat plane on a surface. Air pressure will hold that to the surface yes. The same way air pressure holds down a sheet of newspaper to a table.
As I say, they're vehicles, the air pressure is not pushing them down. It's pushing inwards on them as you and I have pointed out.
So in this circumstance the air pressure is not pushing them down. Can it push things down ? Yes. But not these things.

You seem to be confusing drag and lift.
Drag (air resistance) is a frictional force that counteracts acceleration, in case of no acceleration it will reduce velocity.
Lift is the resulting force of pressure differences between a fluid above and below an object.

I'd say this more a semantical objection that we seem to be at ends about. Air resistance is a colloquialism, and certainly is applicable in many eyes to most areas of fluid dynamics.

Myself; I regard it as a ubiquitous term encompassing any force derived from passing fluids.

However, it doesn't matter if you presume my statements to be about drag or lift. Both words fit under the given conditions. Drag is not a symmetrical force and is a function of surface tension, this in itself is capable of 'pushing down' onto the car/truck.
