Answer:
According to Newton’s First Law of Motion: Every object remains in the state of rest or uniform unless it is acted by an external unbalanced force. In the case of the aeroplane, if the lift is equal to the weight, there is no change in vertical motion. If the thrust is equal to drag, there is no change in the horizontal motion.
Newton’s Second Law of Motion states that a body of mass (m), subject to a force F undergoes acceleration (a), F = ma. Hence, in this case, the amount of force produced by the lift overcomes the gravity to move.
Newton’s Third Law of Motion states that every action has an equal and opposite reaction. The four forces acting on the aeroplane helps to maintain a flight. When the angle of attack of the air increases, the resultant force from the deflection of the air both above and below the wing is also a major component to lift. As the air is deflected downwards, it pushes on the wing in an equal and opposite direction.
