When a plane is lifting off which force is greater: air resistance or thrust?

When a plane is lifting off which force is greater: air resistance or thrust?When a plane is lifting off which force is greater: air resistance or thrust?Depends.

If the A/C is accelerating while lifting off, then f = ma = T - F %26gt; 0 is the net force and thrust T %26gt; F the air resistance (and ground friction with the wheels) so that a %26gt; 0.

But if the plane is lifting off at a constant velocity, then f = ma = T - F = 0 so that a = 0 and T = F, the thrust equals the resistance while lifting off.
