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.

Rocket aerodynamics is the study of how air flows over a rocket and how this affects drag and stability. The nose cone and fins of a rocket are designed to minimise drag (air resistance) and to provide stability and control (keep it pointing in the right direction without wobbling).ins control direction and stability. The stability of a rocket is its ability to keep flying through the air pointing in the right direction without wobbling or tumbling. Fins are used on smaller rockets to provide this stability and control direction.
