In the experiment to measure the coefficient of kinetic friction by sliding a block down on inclined plane, it is required that the block move at constant velocity. Why is this requirement necessary? 5. Frictional forces on a block on an inclined plane are directed down the plane (TRUE/FALSE). 9. How does the coefficient of kinetic friction depend on the constant speed of a moving object?
