What is thrust?

What is thrust?

• A. The upward force generated by the wings
• B. The forward force produced by aircraft engines
• C. Air resistance against the aircraft that slows it down
• D. Gravity acting on the aircraft

Answer: (B)

Thrust is the forward force produced by the aircraft's engines that propels the airplane through the air. It comes from engines pushing air backward, and the action-reaction pair pushes the airplane forward. This forward push is what Overcomes drag, the air resistance that slows the plane, and allows the aircraft to speed up or maintain its speed. Lift, by contrast, is the upward force generated by the wings, which keeps the plane in the air but doesn’t move it forward. Drag is the resistance that acts opposite to your motion, and gravity pulls the plane downward. So the description that matches thrust is the forward force created by the engines.
