Four main forces: thrust, drag, lift, and weight in steady flight. Thrust opposes drag and acts parallel to longitudinal axis. Drag opposes thrust and acts rearward parallel to relative wind. Lift opposes weight and acts perpendicular to flight path. Weight pulls aircraft downward through center of gravity

Four fundamental forces govern aircraft motion: lift, weight, thrust, and drag. All forces are vectors with magnitude and direction. Pilot controls lift through angle of attack and airspeed. Weight is controlled by payload and fuel uplift
Kinetic energy is energy required to accelerate from rest to stated velocity. It is a scalar quantity measured in Joules. Formula: KE = 1/2mv²
