Brick pavers generally cost 50 cents or more per brick or between $3 and $15 per square foot, but expect higher prices if you choose unusual sizes, rare colors or odd shapes. Some price quotes for brick pavers include: 1  Red brick pavers: $0.50 - $5 per brick.  Gray brick pavers: $0.50 - $10 per brick.
Aerodynamics. Aerodynamics is the study of forces and the resulting motion of objects through the air. Studying the motion of air around an object allows us to measure the forces of lift, which allows an aircraft to overcome gravity, and drag, which is the resistance an aircraft âfeelsâ as it moves through the air.Everything moving through the air (including airplanes, rockets, and birds) is affected by aerodynamics.tudying the motion of air around an object allows us to measure the forces of lift, which allows an aircraft to overcome gravity, and drag, which is the resistance an aircraft âfeelsâ as it moves through the air.

A plane's ability to get off the ground depends on four main forces and how they interact with each other. These four forces are thrust, drag, lift, and weight. Thrust is the force created by the plane's engine that pushes it forward. It is similar to the force of a car's engine pushing the car down the road. Drag is the force of the wind pushing back on the plane. Airplanes must contend with the force of drag whether or not it is a windy day because, even on a still day, the effect of air movement is created as the plane flies through the air. Drag pushes the plane in the opposite direction from the direction of thrust.
