Phys 325 Discussion 2 – Drag Force Intuition
... The origin of the quadratic drag force on any projectile in a fluid is the inertia of the fluid that the projectile has to push as it moves forward. (a) Assuming the projectile has a speed v and a cross-sectional area A (i.e. the area perpendicular to its velocity), and that the fluid through which ...
