What are the 4 laws of flying?
There are four forces that act on things that fly. These are weight, lift, thrust, and drag. Each of these plays a key role in keeping an aircraft in the air and moving forward. Newton’s 3rd Law says for every action, there is an equal and opposite reaction. An aircraft is a perfect real-world example of force pairs. Even sitting on the ground, the plane exerts a force down on the ground and the ground exerts an equal force back up on the plane.
