Answer:
Weight , Drag , Thrust , Normal force
Explanation:
It is given that a jet plane is speeding during takeoff. The air resistance is negligible.
Therefore, the forces that acts on the jet plane are :
Weight
As the plane has some mass, the weight of the plane is acted upon it. The weight is acted in the downward direction.
Normal force or the Lift
The lift force is the force that helps the plane to move up in the air and it opposes the weight of the plane. It is the normal force to the weight of the plane and this force holds the plane in the air.
Thrust
The thrust force is the force which helps to move an aircraft in the direction of the motion. This force is created by the jet engine. This force moves the plane in the forward direction through the air.
Drag
Drag force is caused due to the difference in the velocity of the solid objects and the air. The drag force opposes the forward motion of the jet plane.
