Airplanes have to overcome more than just one force in order to fly. Gravity, of course, is the most obvious one. Drag is another one. The silhouette/cross section/wetted area which the airplane presents to the wind is one obvious form of drag. Then there's induced drag, the friction of the air over the aircraft skin, which increases as the speed of the aircraft increases. There are also incidental sources of turbulence that contribute to induced drag. All of these are overcome with clever design and lots of power.
What else can I help you with?
What force must be created by an airplane in order to overcome drag?
The thrust force produced by the airplane's engines must be greater than the drag force acting against it in order to overcome drag and maintain forward motion. This allows the airplane to continue moving through the air and generate lift to stay aloft.
In order for an airplane to remain in level steady flight what must happen to the four forces?
In level steady flight, lift force equals weight, and thrust force equals drag force. This balance of forces keeps the airplane in level flight without ascending or descending.
What is thrust for an airplane?
Thrust is the produced force of the aircraft that propels the aircraft forward in order to overcome drag. Drag is the natural force of the air that resists the motion of the aircraft.
What force does a rocket have to overcome to move skyward?
A rocket has to overcome the force of gravity in order to move skyward. This force pulls the rocket downward and needs to be overcome by the thrust generated by the rocket's engines in order to achieve lift-off.
Is lift needed to overcome drag?
Yes, lift is needed to overcome drag in order for an aircraft to maintain level flight. Lift is the force generated by the wings that counteracts the force of drag acting in the opposite direction. This balance allows the aircraft to move forward through the air.
In a machine the effort force you apply is used to overcome a what force?
In a machine, the effort force you apply is used to overcome a resistance force. The resistance force is the force that the machine acts against in order to perform work.
What is the force to be overcome by a simple machine called?
The force to be overcome by a simple machine is called the input force or effort force. This is the force applied to the machine in order to make it work against the resistance force or load.
How much lift does it take for an airplane to get off the ground?
In order to lift off the ground, the lift force (the upward force generated by the wings) has to be at least as great as the weight of the aircraft. Lift and weight are opposing forces and are equal in straight and level flight.
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 do you call the weight or resistance that needs to be overcome?
That is referred to as the "load" or "force" that needs to be overcome in order to achieve a desired movement or outcome.
What is the force you apply to your lever is called?
The force applied to a lever is called the effort force. This force is used to overcome resistance at the load end of the lever in order to perform work.
What force is opposing the buoyant force?
The force opposing the buoyant force is the force of gravity. Gravity pulls objects downward, creating a force that must be overcome by the buoyant force in order for an object to float in a fluid.
