lift = 1/2 air density x velocity squared x surface area

Faster. This is how lift is produced over the surface of the wing because the pressure is decreased over the top surface

Lift=Coefficient of lift x 0.5density of air x speed (squared) x surface area.

A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.

The force of lift is what makes airplanes fly. It results from an effect called the Bernoulli Effect when air passes over and airfoil, a surface which is curved on the top and flat on the bottom. The air passing over the upper surface has farther to go and therefore goes faster than that passing over the lower surface. The faster-moving air causes the pressure above the airfoil to reduce, causing the wing to rise.
