Document Summary

Decreasing the area facing the oncoming flow, taper the leading side (making it smaller prevents the air from moving abruptly. One can only attain drift on an object that is rounded on one side, and flat on the other. The coefficient of drag (cd) indicates how streamline a projectile is (the more streamlined, the lower cd. A represents the frontal area of the projectile facing the flow. V2 means if velocity doubles, fluid drag quadruples. Terminal velocity is reached when all of the resistive forces = the motive forces. As the body falls in mid-air, the drag increases proportional to the acceleration. Drag increases as v2 increases (ex: if velocity = 4, drag = 16) A light body reaches terminal velocity sooner than that of a heavy body (ex: badminton bird vs. tennis ball) As soon as the magnitude of air resistance = acceleration, terminal velocity is reached. Effects of streamlining: the body) felt on the body.
