Thrust is defined as?

• A. Drag resisting forward motion
• B. Weight downward due to gravity
• C. The upward force to counter gravity
• D. Force exerted by the engine on air which causes lift or forward propulsion

Answer: (D)

Thrust is the force produced by the propulsion system when it pushes air backward, and the reaction pushes the drone in the opposite direction. In a quadcopter or similar drone, the propellers shove air downward; this momentum transfer creates an upward thrust that counteracts gravity. If the craft tilts, that same thrust can have a forward component, providing forward propulsion. The other terms describe different forces: drag is the resistance that opposes forward motion, weight is the downward pull of gravity, and lift is the upward force generated by rotor aerodynamics to counteract weight. So thrust is the force exerted by the engine on air which causes lift or forward propulsion.
