# Inertia in flight simulation using box2d

I'm trying to simulate flight using box2d and libgdx.

The main problem I am currently experiencing is with inertia: since there is no air, the plane looks like it were drifting.

I wasn't able how to turn off inertia.

I have two ideas:

1. Imitate air resistance by applying force

2. Imitate flight using linear velocity without using any box2d physics

Are any of these two ways correct? Or maybe there is way to turn off inertia?

• Air resistance as (e.g. F=-c*v^2 where c is some factor and v is the velocity). The c factor will most likely change based on velocity and orientation of the airplane since the surface is very different because of the wings.
