'Lift' is an upward force on a plane. Upward force on a bird's wings is also called 'Lift'.
These forces are called drag and gravity. Gravity is the downward force on the plane, keeping it from flying, but if the lift, the opposing force, is strong enough, you will achieve flight. Drag is the force pulling you back, making it harder to go forward. This force is produced by air pressure on the front of the plane. The opposing force in this case is thrust, which makes the plane move forward.
No. We call the upward component of force "lift"."Thrust" is the component of force forward ... the direction the plane's nose points.
The upward angle of the wing of an aircraft is the dihedral angle. It is vital because it keeps the plane from unexpectedly rolling while in flight.
Air resistance is not a downward force; it acts in the opposite direction of an object's travel. When a plane is in flight the forward force provided by the engines works against the backwards force of air resistance. If the engines are turned off the plane will begin to slow down. As a plane moves foreward the air moving over its wings creates an upward force called lift, which works against the pull of gravity.

Zero - otherwise it would fall out of the sky.

There are five main forces that act upon a plane. The first force is gravity, a force acting toward the earth and hence downwards. The second force is thrust, a force that is generated by an engine of sorts and acts perpendicular to the force of gravity or straight. The third force is drag which is caused when there is an object that poses an obstruction to direct wind flow. Nothing on earth posses zero drag force. This force acts in the direction opposing thrust. The fourth force acting upon a plane is pitch. This is the angle of elevation of the plane on a complete 180 degrees scale. The ailerons control this force. The final force on a plane is controlled by the rear rudder and is termed as yaw. This force is often confused with the turn axel but is nothing related. This force is the force conrolling the right-left direction of the nose of the plane. Thanks for reading my answer - Rohan Sharma XB 2008 TISB School
The forces acting on the car include: 1) Weight (mass x gravity) of the car. 2) Normal force between the inclined plane at each tire (perpendicular to the inclined plane). 3) Force of static (rolling) friction acting between the tires and the inclined plane (parallel to the plane and acting against the direction of rotation of the tires). 4) Force exerted by the car on the plane (parallel and opposing friction on the inclined plane). 5) Drag force depending on air resistance and velocity of the car. The car is allowed to climb the hill because of the static friction opposing the force it is exerting. Without this friction, it would not be able to climb the hill.
when flight moves the velocity of air above and below the plane is different ..this gives it an upward thrust (according to bernauli's theorem).
The wings on a plane use the scientific law of deflected down-wash. The wings on a plane, or even a bird, are slightly angled upwards. when the propeller pulls the plane to a fast enough speed, huge gusts of wind blow against the wings. The wings force the air downward, and because of every action having an equal or opposite reaction, the plane is force upward. the same thing happens with kites.
