What one of the following four forces does not affect an airplane in flight?

Lift
Drag
Mass
Mass
Forces are always acting on our body, whether or not we can feel them. Those forces are significantly stronger when acting on a body as large as an airplane. The four forces of flight are drag, propulsion, lift, and weight. Thrust and weight are comparable to drag and lift, respectively, when an aircraft is flying straight and level at a constant speed. A high-altitude balancing act is required to maintain the balance of all these forces.
