A desk weighs 500 N with gravity applying that force downward If you apply 275 N upward force and a friend helping you applies 275 N upward force what is the net force applied

50 N upward

Which type of force is exerted on the support ropes of a hammock when you lie in it

Tension

What creates the lift that allows gliders to fly

Unequal Pressure

The aircraft's wing is shaped so that the air passing over the wing moves faster than the air under the wing causing a positive pressure differential, thus creating lift. In simpler terms, it is the air moving above the wing, not below the wing, that causes lift.
