Air Resistance (A Damping force that depends on velocity (F(v)))
Newton's second law
Consider the impact on solving Newton's second law when there is an external Force that is velocity dependent
Frictional forces tend to be proportional to a fixed power of velocity
Linear air resistance (n=1) arises from the viscous drag of the medium through which the object is falling.
Quadratic air resistance (n=2) arises from the objects continual collision with the medium that causes the elements in the medium to accelerate.
Air resistance for rain drops or ball bearings in oil tends to be more linear while canon balls and people falling through the air tends to be more quadratic.
Example: A Sphere moving through air at STP
