Challenge 9: Comparison of Drag-free Model with Air Resistance Model

A new projectile model which compares a drag-free model with a model incorporating the effect of air resistance (using the Verlet method). Here air resistance is modelled as being directly proportional to velocity2, surface area, air density; and indirectly proportional to mass.
