Lift, raise, elevate, get up, bring up – raise from a lower to a higher position; “Raise your hands”; “Lift a load” 2. lift up – fill with high spirits; fill with optimism; “Music can uplift your spirits”.
The popular explanation of lift. Students of physics and aerodynamics are taught that airplanes fly as a result of Bernoulli’s principle, which says that if air speeds up the pressure is lowered. Thus a wing generates lift because the air goes faster over the top creating a region of low pressure, and thus lift.
The modern lift equation states that lift is equal to the lift coefficient (Cl) times the density of the air (r) times half of the square of the velocity (V) times the wing area (A).
