What are the coefficients of drag and lift?

For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.

Lift is an aerodynamic force that results from the air passing over the curvature of the wing. It causes a reaction. A high pressure on the bottom of the wing and a lower pressure on top of the wing....

That depends on the bear in question.

They are the 4 forces.

In aircraft aerodynamics, the lift-to-drag ratio, or L/D ratio, is the amount of lift generated by an aerofoil, divided by the drag it creates by moving through the air. A higher or more favourable...
