"Lift" is the force that acts opposite to gravity. If 'lift' can be made to exceed

the weight of the craft, then the net vertical force on it is directed upward, and

the craft can rise.

When are we use lift force for force diagram?

Lift force is used in force diagrams when analyzing the motion of objects that interact with a fluid, typically in the context of aerodynamics or hydrodynamics. It is most commonly applied to aircraft, birds, and other vehicles in flight, where the lift acts perpendicular to the direction of motion and counteracts the weight of the object. In these diagrams, lift is represented as an upward force that balances or exceeds gravitational force to achieve sustained flight. Additionally, lift can also be relevant in scenarios involving vehicles moving through water or other fluids where buoyancy plays a role.


What is the lift force in an aircraft?

The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.


What is the lift drag thrust weight formula used in aviation to calculate the forces acting on an aircraft during flight?

The lift, drag, thrust, and weight formula used in aviation is a way to calculate the forces acting on an aircraft during flight. It states that lift must equal weight and thrust must equal drag for the aircraft to maintain level flight.


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 of flight and why do they affect planes?

The four forces of flight are lift, weight (gravity), thrust, and drag. These forces affect planes by enabling the plane to generate lift to counteract gravity (weight), provide thrust for forward motion, and counteract drag to maintain speed and altitude during flight.

Where is the lift in a vertical flight?

there is no lift in vertical flight, it is all thrust.


What type of feathers are long and extend beyond the body for lift?

The type of feathers that are long and extend beyond the body for lift are called flight feathers, or remiges. These feathers are primarily found on the wings and are specifically adapted for aerodynamics, allowing birds to achieve lift during flight. They play a crucial role in enabling various flight maneuvers and stability in the air.

What feathers assist a bird during flight and landing?

Primary flight feathers support a bird during flight by providing lift and thrust, while secondary flight feathers help with maneuverability and stability. Tail feathers play a crucial role in steering and braking during landing by controlling the bird's direction and speed.

What statement is true about an airplane during flight?

During flight, an airplane is subject to four primary forces: lift, weight, thrust, and drag. Lift, generated by the wings, opposes the weight of the airplane, while thrust produced by the engines counters drag, which resists forward motion. For stable flight, these forces must be balanced appropriately, allowing the aircraft to maintain altitude and speed. Additionally, the design and aerodynamics of the airplane play a crucial role in its flight efficiency and performance.
