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.

Is air resistance fluid friction?
At sub-sonic speeds, air resistance is fluid friction. At supersonic speeds, it is not.
Which is greater sliding friction or rolling friction?
sliding friction
Why sliding friction greater than rolling friction and if the area of contact is same?
The FORCE of Friction is INDEPENDENT of Surface Area. Only the 'Coefficient of Friction', and the Force between the two Surfaces. Sliding Friction is greater than Rolling Friction ONLY if the Coefficient of Friction is GREATER for the Sliding Surfaces.
Does friction affect stopping distance?
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
Which type of friction is usually greater static friction or kinetic friction?
Usually static.
What is the difference between kinetic friction and state friction?
it speeds up and speeds down

Static friction is usually greater than?
kinetic friction
What is Static friction is usually greater than?
sliding friction
Which type of friction is usually greater static friction or kinetic friction?
Usually static.
Is rolling friction or fluid friction greater?
Fluid friction is greater.By: Adarsh kv1
What is the relationship between mass and force of sliding friction?
they are directly proportional, the greater the mass, the greater the sliding friction
