Answer:
Friction is roughly proportional to speed
Explanation:
Friction of one dry object against another is fairly constant over a fairly large velocity range. For a solid object moving at a high speed through some fluid, friction is roughly proportional to the square of velocity. However, friction is roughly proportional to velocity for a solid object moving at a low speed through a fluid.

the frictional force is proportional to the velocity for small velocities.
