Is thrust dependent on air density?
Yes, thrust is dependent on the density of air. Thrust is the force of flight that pushes in the direction of the aircraft’s motion. By Newton’s second law, the force needed to accelerate an object increases with the object’s mass. The greater the density of the fluid, the greater its mass. A greater density means a greater mass, and a greater mass means a greater force. Thus, the amount of thrust generated must increase when the fluid density increases.
