It isn't always - for instance: static friction (standing still) is greater than moving friction.
BUT, Air resistance (or water resistance for boats) increases with speed - quite rapidly. The reason for the increase is that you must move the fluid out of the way in less time as you speed up.
What else can I help you with?
What happens to the magnitude of fluid friction as Speed increases?
As speed increases, the magnitude of fluid friction also increases. This is because at higher speeds, there is more interaction between the moving object and the fluid, resulting in greater resistance and friction.
Why does friction increase as the speed increases?
Friction increases as speed increases because at higher speeds, there are more collisions between the moving surfaces, leading to greater resistance. This results in more heat being generated, which in turn increases friction. Additionally, higher speeds can cause deformation of the surfaces, creating more contact points and thus increasing friction.
Can speed affect friction force?
Actually, friction does depend on velocity. If you stop your car you have to ease up on the brakes as you slow down because friction increases as you slow down. This effect has been observed for objects travelling at bullet velocities. Friction decrease as speed increases.
What friction is greater than sliding friction?
Static friction is greater than sliding friction. Static friction occurs when an object is at rest and an external force is being applied to move it, requiring a greater force to overcome the initial resistance compared to when the object is already in motion and experiencing sliding friction.
Do maglev trains have zero friction?
Yes, there is friction from movement through the air. The higher the speed of the train and the greater the surface area of the train impacting the air, the greater the friction, and hence the temperature, energy loss and limitations on speed. In the future we will integrate this technology with zero/low pressure tubes, made from carbon fiber or some other materials that will allow these trains to operate with little to no friction and therefore unimaginable speeds, theoretically tens of thousands of miles per hour, and at a fraction of the energy required to lift an airplane from the ground and withstand friction and energy loss at super sonic speeds. These trains will likely be built underground for a number of reasons and likely begin by transporting freight.
What is the difference between kinetic friction and state friction?
it speeds up and speeds down

How does speed affect friction?
That depends on the exact circumstances. Solid friction hardly depends on the speed at all. In fluid friction, the situation is more complicated. Usually there is some range of speeds for which friction is more or less proportional to speed; at higher speeds, the force of friction may even become proportional to the square of the speed.
Which friction is greater sliding friction or static friction?
Static friction
