1-1 When pressure is applied to the airplane controls, one or more of the basic forces changes in magnitude and becomes greater than the opposing force, causing the airplane to accelerate or move in the direction of the applied force.
15 kwi 2024 · From lift and drag to control surfaces and aerodynamic forces, this quiz will challenge your understanding of how airplanes stay aloft and maneuver through the air. Answer questions on Bernoulli's Principle, the four forces of flight, control surfaces, and more.
3 Ground Lesson Content T h e F o u r F o r c e s - Airplanes in straight and level flight are subject to 4 basic forces: We i g h t - We i g h t is the downward force provided by gravity. As an airplane sits stationary on the ground, the only force acting on it is gravity.
18 When considering air: 1. Air has mass. 2. Air is not compressible. 3. Air is able to flow or change its shape when subject to even small pressures. 4. The viscosity of air is very high. 5. Moving air has kinetic energy. The correct combination of all true statements is: [A] 1 and 4. [B] 1, 3 and 5. [C] 2, 3 and 4. [D] 1, 2, 3 and 5.
Which one of the following statements about the lift-to-drag ratio in straight and level flight is correct? A) The highest value of the lift/drag ratio is reached when the lift is equal to, the aircraft weight.
By speeding up the air over the top you have reduced the pressure above the paper, so the air pressure under the paper pushes it up. The harder you blow the more it will rise.
Introduction: The principles of flight are the aerodynamics dealing with the motion of air and forces acting on an aircraft. Lift is the most apparent force, as it's what we think of as giving an aircraft the ability to fly. Thrust provides a method with which to move the aircraft.
