What are the 4 types of aerodynamics?
The four forces acting on an aircraft in straight-and-level, unaccelerated flight are thrust, drag, lift, and weight. The Third Law states that “for every action, there is an equal and opposite force. It was developed by Sir Isaac Newton in the 17th century. The four forces of flight are always forces acting on an aircraft: thrust (forward), drag (rearward), lift (up), and weight (down).
