Question

Do objects with more mass have more friction

Answer 1

yes. object with more mass tend to have more friction. for example if you slide a heavy box across the floor, it will have more friction with the floor due to gravity.

Answer 2

Yes. An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface of the light object.
