How does gravity affect an aircraft in flight? When an airplane flies, it must first overcome two primary forces–weight and drag. Weight is the force of gravity acting to pull the plane to the ground, and it is overcome through lift. Lift results in the plane rising into the air.
How does gravity affect flight?
If gravity and drag are bigger than lift and thrust, the plane goes down. Just as drag holds something back as a response to wind flow, lift pushes something up. The air pressure is higher on the bottom side of a wing, so it is pushed upward.
Why are planes not affected by gravity?
Planes do not actually defy gravity, though. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings.
What is gravity in flight?
BACKGROUND INFORMATION: Gravity is the force pulling the plane down. When the gravity is stronger than the lift, the plane goes down. Helicopters are really airplanes with moving wings called rotors, which replace the fixed wings and propellers used on an airplane.
Can planes fly without gravity?
Aboard a specially modified Boeing 727-200, G-FORCE ONE®, weightlessness is achieved by doing aerobatic maneuvers known as parabolas. Specially trained pilots perform these aerobatic maneuvers which are not simulated in any way. ZERO-G passengers experience true weightlessness.
How do planes use gravity to their advantage?
Gravity helps create lift for paper airplanes. … Lift is the force that pushes an aircraft into the air. When paper airplanes are thrown up, gravity pulls them down. This movement causes a difference of air pressure on the airplane wings, which then causes lift.
Where should the center of gravity be on a plane?
1 Answer. The center of gravity (cg) should be right above or below the center of lift. Otherwise the airplane will start to pitch and never stabilize. But you do not select the position of the cg, instead, you adjust the center of lift such that lift will act along the same axis as weight.
Who discovered gravity?
Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.
Which force of flight is produced to overcome drag?
To overcome drag, airplanes use a propulsion system to generate a force called thrust. The direction of the thrust force depends on how the engines are attached to the aircraft.
How does weight affect a plane?
Weight is the force that pulls the plane down due to gravity. In order for the plane to get off the ground, the plane must overcome its weight throught the force of lift. The more mass the plane has the more lift it has to produce in order to get off the ground.
What is the strongest part of a plane?
The landing gear is the strongest part of an aircraft; it takes the entire weight of the aircraft plus safety factors and off-axis (side loads and moments).
Which of the forces of flight is the most important?
Air in Motion: Aerodynamics and the 4 Forces of Flight
- Lift. Perhaps the most importance force to a pilot is lift. …
- Weight. Weight opposes the force of lift in flight, directing down toward the center of the Earth. …
- Drag. Drag is the aerodynamic force that opposes the motion of the airplane through the air. …

What causes drag?
Drag is generated by the difference in velocity between the solid object and the fluid. There must be motion between the object and the fluid. … We can think of drag as aerodynamic friction, and one of the sources of drag is the skin friction between the molecules of the air and the solid surface of the aircraft.
Does zero gravity exist?
Contrary to popular belief, there’s no such thing as zero gravity. Weightlessness and zero gravity are two different things. The earth’s gravity keeps the moon in orbit. And astronauts are generally much closer to earth than the moon is, which means that the earth’s pull on them has to be much stronger.
Does 0g feel like falling?
Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time. … The astronauts inside it experience weightlessness, floating around in no particular direction.
Is there a zero gravity room on earth?
The Zero Gravity Research Facility is NASA’s premier facility for ground based microgravity research, and the largest facility of its kind in the world. The Zero-G facility is one of two drop towers located at the NASA site in Brook Park, Ohio. The Zero-G facility has been operational since 1966.
