The object accelerates.
It has it's shape to reduce drag and alow it to fly
The arrow opposite the direction of travel is the air resistance or drag.
A paper airplane is affected by its shape in just about every way. Drag, efficiency and performance are all affected by the aircraft's shape.
Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and gravity (or weight).In simple terms, drag is the resistance of air (the backward force), thrust is the power of the airplane's engine (the forward force), lift is the upward force and gravity is the downward force. So for airplanes to fly, the thrust must be greater than the drag and the lift must be greater than the gravity (so as you can see, drag opposes thrust and lift opposes gravity).This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and gravity are balanced. During a descent, gravity exceeds lift and to slow an airplane drag has to overcome thrust.
Lift, weight, thrust and drag.
Drag
The four basic forces acting on an aircraft are Lift, Weight (Gravity), Thrust, and Drag. In order for an aircraft to ascend, Lift must be greater than Weight, and Thrust must be greater than Drag.
Aerodynamics help reduce drag so the engines can produce thrust.
Lift equals weight and thrust equals drag.
Lift, Gravity, thrust and drag
lift and thrust overcome weight and drag
yes
There are four forces that act on an airplane that keeps it at a level altitude. Thrust, drag, weight, and lift determine whether a pilot flies at a level altitude.
Thrust (forward), Gravity (down), Drag (back), Lift (up)
