aer (air) + dynam (force) + -ics (field of study) = "the study of the forces of air." It explains why a wing produces lift and why cars and planes are shaped to slip through the air with the least resistance. The everyday adjective aerodynamic — sleek, built to cut through air — comes straight from it.
