As an object moves faster through a fluid (like air or water), it creates more turbulence and pressure differences around it, leading to increased drag force. This drag force is caused by the friction and resistance that the fluid exerts on the moving object, which increases as the speed increases.
What else can I help you with?
How does aircraft drag increase with speed?
Drag increases by the square of velocity increase, for example, tripling speed increases drag by a factor of nine!
How can you increase drag?
You can increase drag by increasing the surface area of an object, changing its shape to be less streamlined, or by roughening its surface. Additionally, increasing the speed of an object can also increase drag.
Will speeding up decrease the drag force on an airplane?
In general (special exceptions may apply) increase speed = increase drag.
Does wave speed increase as gravity increases?
No, wave speed does not increase as gravity increases. The speed of waves depends on the medium through which they are traveling, not on the force of gravity. In a given medium, the speed of waves is determined by its properties such as density and elastic properties.
Why Is it important to reduce drag?
Reducing drag is important because it increases efficiency, saves energy, and improves performance in various applications such as vehicles, aircraft, and sports equipment. Drag reduction helps to decrease fuel consumption, increase speed, and enhance overall aerodynamic stability.

What increases as the speed of an object increases?
As the speed of an object increases, its kinetic energy and momentum also increase. Additionally, the drag force acting on the object due to air resistance will also increase with speed.
What happens to total drag as airspeed is increased from the stall towards Vne?
Total drag initially decreases as airspeed increases from stall to a certain point, as the airplane moves into its most aerodynamically efficient speed range. Beyond that point (Vne), total drag increases due to the combined effects of parasite drag and induced drag rising with airspeed, leading to a significant increase in total drag.
How can you increase drag?
You can increase drag by increasing the surface area of an object, changing its shape to be less streamlined, or by roughening its surface. Additionally, increasing the speed of an object can also increase drag.
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases

What are the purposes of the slats and flaps of an airplane's wings?
Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.
Why Is it important to reduce drag?
Reducing drag is important because it increases efficiency, saves energy, and improves performance in various applications such as vehicles, aircraft, and sports equipment. Drag reduction helps to decrease fuel consumption, increase speed, and enhance overall aerodynamic stability.
If the speed of an object increases its kinetic energy does what?
If the speed of an object increases, its kinetic energy also increases. Kinetic energy is directly proportional to the square of the object's speed, so a small increase in speed can result in a larger increase in kinetic energy.
When water skiing if the boat was going fast would it create more drag or less drag for the skier?
The drag vs Speed graph will be a curve, with it's minimum at some speed greater than zero. At slow speed, the skier needs to angle the sji at a high angle to the water in order to produce enough lift to stay upright. This is known in Aerodynamics (and, I imaging, Hydrodynamics) as Induced drag. As the speed incearses, the skier can angle the ski at a lesser angle, thus reducing drag. However, as speed increases further, the frictional and drag forces associated both with the movement of the ski on the water, and the skier through the air increase ("Form and Parrasite" drag). The sum of all drag will reach a minimum where induced drag has reduced, but the other types of drag have yet to significantly increase. Drag will be greater at EITHER a slower OR faster speed than this minimum figure.
How fast is a drag-line speed?
The speed of a drag-line might me unable to know because of all of the add-ons you can add on it and the speed might allways increase and decrease.
