yes
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.
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.
It will stall and begin to lose altitude.
The car (or plane/whatever else it is) accelerates. This means that it gains speed
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.
When thrust is greater than drag, the aircraft will accelerate and increase its speed. This will lead to a climb in altitude or a change in direction due to the increased force pushing the aircraft forward.
Lift equals weight and thrust equals drag.
Lift, Gravity, thrust and drag
The force of an airplane that opposes thrust is called drag. Drag is the resistance force that acts opposite to the direction of motion of the aircraft and is caused by the interaction of the aircraft with the surrounding air.
lift and thrust overcome weight and drag
yes
The thrust force produced by the airplane's engines must be greater than the drag force acting against it in order to overcome drag and maintain forward motion. This allows the airplane to continue moving through the air and generate lift to stay aloft.
