Question

What happens to static friction when a wooden block is moved with increasing speed on a horizontal surface? Why? ​

Answer 1

Answer:

The value of limiting friction, which is nothing but the maximum of static frictional force and minimum of kinetic frictional force applied by the surface to just start the relative motion, decreases as the block is moved with increasing speed on a horizontal surface.

Answer 2

Answer:

The value of limiting friction, which is nothing but the maximum of static frictional force and minimum of kinetic frictional force applied by the surface to just start the relative motion, decreases as the block is moved with increasing speed on a horizontal surface
