Question

What happens to the coefficient of friction when the weight is increased? Why is this?

Answer 1

Answer:

The coefficient of friction does not change.

Explanation:

The reason for this is that the coefficient friction depends only on one variable, which is the nature of the surfaces in contact. Therefore, weight has no effect whatsoever on the coefficient of friction. hence, No change occurs in the coefficient of friction if the weight is changed.

hope it helped ya.

Answer 2

Answer:

Usually the coefficient of friction remains unchanged

Explanation:

The coefficient of friction should in the majority of cases, remain constant no matter what your normal force is. When you apply a greater normal force, the frictional force increases, and your coefficient of friction stays the same. Here's another way to think about it: because the force of friction is equal to the normal force times the coefficient of friction, friction is increased when normal force is increased.

Plus, the coefficient of friction is a property of the materials being "rubbed", and this property usually does not depend on the normal force.
