This insight is a model of a parachute falling through the air. The objective is to determine--by comparing to actual data of a falling parachute--whether the drag coefficient is proportional to the velocity of the parachute, or it's square.

This differential equation model simulated the motion of a falling parachute. In particular, the mass of the parachute and velocity are used to calculate a drag force against the downward acceleration of the parachute towards the ground.
