Question

What forces act on an airplane to keep it in the air? If the airplane is traveling at a constant velocity, what could be said about the magnitudes of the forces? ​

Answer 1

Let's see

$\\ \sf\longmapsto \overrightarrow{drag}$

$\\ \sf\longmapsto \overleftarrow{Thrust}$

$\\ \sf\longmapsto Lift\:Force\uparrow$

$\\ \sf\longmapsto Acceleration\:due\:to\: gravity\downarrow$

Net force is 0
