A plane needs to overcome its weight with lift to become airborne. Lift is generated primarily by the wings as air flows over and under them, creating a pressure difference. Additionally, the plane must counteract drag, which is the resistance it faces as it moves through the air. Achieving sufficient lift requires a combination of wing design, speed, and angle of attack.
What else can I help you with?
Why is lift important in flight?
Because the plane has to overcome the force of gravity and it has wings to create lift to make the aircraft fly.
How much lift does an airplane need to fly?
An airplane needs enough lift to overcome its weight in order to fly. The amount of lift required depends on factors such as the aircraft's weight, velocity, wing design, and air density. Pilots can adjust the airplane's angle of attack and airspeed to generate the necessary lift for flight.
What is the effect using an inclined plane to lift an object?
no
What are the forces of a plane flying at a constant height?
The forces acting on a plane flying at a constant height include lift, weight, thrust, and drag. Lift counters weight to keep the plane in the air, and thrust is provided by the engines to overcome drag and maintain speed.
What energy does a jet plane need at the point of takeoff?
A jet plane needs a significant amount of kinetic energy for takeoff, which is generated by the engines providing thrust to overcome drag forces and lift the aircraft off the ground. Additionally, potential energy is required to lift the plane against gravity. The engines must work at full power during takeoff to generate enough speed and lift for the aircraft to become airborne.
Why do you need weight on a plane to make it fly?
I'm not sure what you mean by "need" since weight is a concomitant - everything used to construct an aircraft has weight. It's a fact of life.Aircraft designers do everything possible to reduceweight.
Why is a force needed on a plane?
A force is needed on a plane to counteract the forces of gravity and drag, allowing the plane to lift off the ground and maintain altitude. The force generated by the engines helps propel the airplane forward and create lift, enabling it to overcome gravity and stay in the air.
What are the four forces that act on planes?
The four forces that act on a plane in flight are lift, weight (gravity), thrust, and drag. Lift is generated by the wings to overcome gravity (weight), while thrust from the engines propels the plane forward to overcome drag, which is the resistance of the air against the forward motion of the aircraft.
Lift must be than gravity in order for a plane to stay in the air?
Lift generated by the wings of a plane counteracts the force of gravity pulling it down, allowing the plane to stay in the air. For a plane to achieve lift greater than gravity, it must generate enough thrust through its engines to maintain forward motion and generate sufficient lift from its wings to overcome the force of gravity.
Can a plane fly without wings?
While there have been some wingless "lifting body" experimental aircraft. All conventional airplanes get the the majority of their lift from their wings and cannot fly without them. No. By definition, A PLANE is a fixed-wing aircraft. The wings are absolutely necessary for lift.
What is the force used in the taking off of the plane?
The main force used in the takeoff of a plane is thrust generated by the engines. This thrust propels the plane forward and allows it to overcome drag, enabling the wings to generate lift for the plane to become airborne. Additional factors like lift from the wings and rotation of the aircraft also play a role in the takeoff process.
Why does an airplane need more lift then weight?
Obviously so it can overcome gravity and take off.
