The article discusses the forces acting on a falling object in respect to the drag forces and reynolds numbers. The article suggests for varying Reynolds numbers, the force of drag equation is written as such:
$F[d] = kv^n$
So the forces acting on the object will be described by the function:
$−mg − kv^n = ma$
When the solution of that DE will derive from the reynolds number.
k is the air resistance coefficiant, and its units are N/sec.
How do the units make sense for reynolds numbers greater than 1?
