What does a lower kinetic coefficient mean compared to a higher one? Does a higher one just require less friction force to move it? ( pulley system lab where there are two masses and its at constant velocity )
Homework Answers
friction is a resistive force acting in the direction apposite to that of motion.
The coefficient is ratio of frictional force to the normal force and has value less than 1.
The lower the kinetic coefficient means, less resistance to the motion of the object on a particular surface and higher means more resistance to the motion.
Since, Ff = uk N
the higher the coefficient, the more will be the frictional force and more work/force will be required for causing movement of the object against it.

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?

Please show all work, equations used, and free body diagram. Two masses are connected by a string (ignore the mass of the string), one is on an incline and the other is being suspended by a pulley in the air (Pulley is also massless and frictionless).
