Question

If the mass of an object increases, predict what will happen to the coefficient of sliding friction.

A.The coefficient of sliding friction will increase.
B.The coefficient of sliding friction will decrease.
C.The coefficient of sliding friction will stay the same.
D.The coefficient of sliding friction will decrease by half

Answer 1

If the mass of an object increases, the coefficient of sliding friction will decrease.

Picture you were sliding a small heavy box across the floor, verses a bigger lighter box which was still the same weight, which would be easier to move? The big box, so the sliding friction decreases.

Answer 2

If the mass of an object increases, the coeficient of sliding friction will increase because there is more wieght over the surface where the object is standing and it is going to be harder to pull or push it.
