Which is the primary forward force acting on the airplane during powered flight?

Explanation:
Thrust is the primary forward force acting on the airplane during powered flight. It’s produced by the propulsion system and acts along the aircraft’s long axis in the forward direction, pushing the airplane through the air. This forward push is what overcomes drag, the air’s resistance acting backward. Lift and weight act mainly vertical—lift up, weight down—so they don’t provide forward propulsion. In steady level flight, thrust balances drag, keeping speed constant; if thrust exceeds drag, the airplane accelerates, and if drag exceeds thrust, it slows down. So the forward motion comes from thrust, not from lift, weight, or drag.
