Flight science

From Wikipedia, the free encyclopedia

Flight science relates to the science orientated part of flight. For an airplane to fly these four important science practices must be applied:

• Weight - caused by gravity, pulls everything toward the ground.

• Lift - caused by air moving over the wings, acts upward against weight.

• Drag - caused by air resistance, acts in the opposite direction to motion.

• Thrust - caused by an engine, overcomes the force of drag.

Generally, if the plane is moving forward, it means that thrust is overcoming drag. If the plane is climbing, the force of lift is greater than the force of weight. If the plane is descending weight is greater than lift.^[1]
