Hello, I have a question for a project I'm currently doing:

In a tunnel with no gravity, there is a constant wind blowing through. A sphere in the middle of the tunnel is completely motionless to start with, but obviously will experience a force from the wind and start moving in the same direction.

What function can I use to express force over time on the sphere by the wind? What about speed of the sphere over time? What if instead the sphere is in free fall with the same horizontal wind?

I would love to learn more about air drag for a situation like this, I'd appreciate any links to further reading material.
