Document Summary

Cannot see lift or drag but are impacted by bother everyday. What pulls a 747 off the gorund at takeoff. Bernoulli"s principle: when air is split, higher velocity above the wing. High flow velocity creates low pressure zone. Wing wans to go from high pressure to low. Fl (lift force) always perpendicular to direction of the oncoming air flow: lift is always created perpendicular to drag. Fl due to difference in pressure zones on opposite sides of projectile. Angle between horizontal (ex: ground) and c of g of projectile. Angle between horizontal and long axis of projectile. Angle between projectile"s long axis and the instantaneous projection velocity vector. Used when talking about lift and drag. The point on a projectile where both lift and drag forces act. Cg and cp out of line = torque, therefore pitch, therefore drag. Cp in front of cg = stall, therefore leading side pitch up.
