How do the forces of lift drag gravity and thrust affect the flight of an airplane?

Let's take the forces one-at-a-time starting with Thrust.
1. Thrust - is provided by the propeller or jet engine; thrust acts to move the plane forward into the air.
2. Lift - As the plane moves forward the shape of the wing (airfoil) causes a pressure difference that exerts an upward force on the wing -- the lift force. As thrust increases lift increases and the plane rises as lift overcomes the downward pull of gravity.
3. Gravity - the force that pulls objects back to Earth. In order to have an object like a plane rise higher the Lift force must be stronger than the pull of gravity. If a plane weighs 10,000 lbs (pull of Gravity) then Lift must be 10,001 lbs or more in order for the plane to rise.
4. Drag - Air moving over a surface experiences friction as the air molecules rub against the surface. Rough surfaces have more friction than smooth ones, but even smooth surfaces have some friction; the net effect is to oppose the forward motion and slow the airplane down. Thrust must be strong enough to overcome the total Drag and accelerate the plane to a speed that generates enough Lift to overcome Gravity and allow the plane to rise.

What are the two forces acted upon the airplane when in flight?
the two forces acted upon the airplane when in flight is Lift/Gravity and Thrust/Drag(:
What are The four forces acting on an airplane in flight are?
Thrust (forward), Gravity (down), Drag (back), Lift (up)
What are 4 forces acting in an airplane during flight?
Forces acting on an aircraft in flight are:gravityliftdrag
What are the four forces acting on an airplane?
Lift Gravity Thrust Drag Lift is the lifting force that allows airplanes to fly, gravity is the force pulling it back down. Thrust is the force that propels an airplane forward, drag is the aerodynamic friction slowing it down. These variables are constantly interacting with eachother, when an airplane is in straight and level flight, these forces are said to be in balance.
Why do the aircraft need a force from their engines to fly at a steady speed?
To overcome drag. The four forces always acting on an airplane in flight are: Lift, thrust, gravity, and drag.
What are the forces that act on an airplane flight?
gravity
What are the two forces acted upon the airplane when in flight?
the two forces acted upon the airplane when in flight is Lift/Gravity and Thrust/Drag(:
Which four forces causes a airplane to become airborne?
There are two forces that causes an airplane to be airborne. They are Thrust and Lift. The other two forces resists the airplane's flight. They are Gravity and Drag.
Center of gravity for an airplane?
The center of gravity is a point on the airplane that the airplane would balance while sitting on the ground. The center of gravity or also called "the CG" is important in trimming the aircraft in flight as the weight has to balance out the forces on the wing. It is also important in aerodynamic maneuvers as the G-forces act through CG.
What are The four forces acting on an airplane in flight are?
Thrust (forward), Gravity (down), Drag (back), Lift (up)
What are the 4 aerodynamic forces of flight?
the four forces of flight are lift,drag,weight/gravity and thrust.I have no clue how to describe them.........i hope that helps!
What are the forces that cause an airplane to fly?
Gravity, force and lift are all forces that cause an airplane to fly. There are more forces depending on what time of airplane is in flight. For example the forces used to keep a comerical jet as to a fighter or military jet. As there are many forces the same the proportion is different there for the air flow if different on each airplane.
What are the forces that affect people in an airplane?
Gravity, G-force (value of force exerted on a body), Air pressureg force?
What are 4 forces acting in an airplane during flight?
Forces acting on an aircraft in flight are:gravityliftdrag
When an airplane is flying straight and level what can be said about the forces on an airplane?
the forces are equal to balance the aircraft in flight
How friction effect the flight of an airplane?
Friction is the force resisting the movement of an object across a surface. For an airplane there is no friction when it is flying. Instead this is referred to as air resistance which produces drag forces. There are several forces acting on the airplane at one time: Thrust, Drag, Lift, and Gravity.
What are the forces of flight?
The four forces that act on an airplane in Flight are Lift (upward generated by the wings), weight (Down generated by gravity, Thrust (forward generated by the engines), and drag (essentially backward generated by the resistance of the aircraft to the atmosphere).
