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 two forces must be equal for a plane to stay at the same altitude?
For a plane to stay at the same altitude, lift force from the wings must be equal to the weight of the plane. Lift force is generated by the wings due to the flow of air over them, while weight is the force acting downwards due to gravity. When these two forces are equal, the plane remains at a constant altitude.
When a plane is flying which 2 forces must be balanced?
When a plane is flying, lift and weight must be balanced to keep the plane level and maintain altitude. Lift is generated by the wings and opposes the force of weight, which is the gravitational force acting on the plane.
When a plane is going ascending what forces act upon it?
When a plane is ascending, the force of lift generated by the wings must overcome the force of gravity pulling the plane downward. The engine also provides thrust to power the plane upward. Additionally, air resistance (drag) influences the speed and efficiency of the ascent.
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.
When the plane is flying at a constant heightwhich two forces must be balanced?
Gravity and lift.

What best describes what must happen in order for a person to lift an object?
The force of gravity must be greater than the mass of the object

What happens to the four forces in order to make an airplane fly?
The four basic forces acting on an aircraft are Lift, Weight (Gravity), Thrust, and Drag. In order for an aircraft to ascend, Lift must be greater than Weight, and Thrust must be greater than Drag.

When a plane is ascending, the force of lift generated by the wings must overcome the force of gravity pulling the plane downward. The engine also provides thrust to power the plane upward. Additionally, air resistance (drag) influences the speed and efficiency of the ascent.

Dose lift have to be greater than weight for a plane to land?
Yes, in order for a plane to land safely, the lift (created by the wings) must be greater than the weight of the aircraft. This helps the plane maintain control during the descent and landing process.
If a plane is flying at a constant speed and height is weight and lift equal?
If weight and lift aren't equal, then there's a net vertical force on the plane, and it must have vertical acceleration.
What does a plane need to make it fly?
Using light-weight materials, an aerodynamic design, power source to get the plane off the ground will all help. Probably the biggest thing a plane needs is enough lift from the wings. The shape of the wing helps create this lift. The wing's profile kind of looks like a tear drop that is flat on the bottom and curved on the top tapering to a point to the rear of the wing. If I remember correctly, this profile creates an area of high pressure on the underside of the wing compared to a lower pressure on top of the wing. This is what creates the lift for the plane. Of course you have to maintain a proper speed to maintain this lift in order to keep the plane in the air...Hope that helps.
