B.Gravity only
C.Gravity an friction only
D.Gravity, friction an applied force
((C. is what I believe it is
Vash/Antonio -- if you are going to pretend to be two different people, at least one of you should learn to spell physics.
No wings or propeller?
To determine the correct answer, let's break down the possible forces that affect a flying airplane:
1. Friction: Friction refers to the resistance encountered by a moving object through contact with a medium. In the case of an airplane, it experiences air resistance or drag, which can affect its motion. However, it is important to note that friction alone does not fully explain the forces acting on a flying airplane.
2. Gravity: Gravity is the force that pulls objects towards the center of the Earth. It acts vertically downward and affects all objects, including airplanes. Gravity is responsible for keeping the airplane in its trajectory and maintaining its altitude.
3. Applied Force: An applied force refers to any external force that is intentionally being applied to an object. In the case of a flying airplane, the engines propel the aircraft forward, providing a thrust force. This applied force is necessary to counteract the resistance of drag and maintain a constant speed.
Considering these explanations, we can conclude that the correct answer to the question is D. Gravity, friction, and applied force. A flying airplane experiences the force of gravity, encounters air friction or drag, and requires an applied force (such as engine thrust) to maintain its motion.
