In order to increase or decrease the magnitude of friction between objects, there are two factors that must be taken into account: the roughness of the two surfaces and the weight of the objects. If the (sometimes microscopic) roughness of the two surfaces are increased, they will be more likely to catch on one another. If the weight of the two objects is increased, the two surfaces will be closer to one another, meaning that the particles of both objects will be more attracted to each other. These slight bonds will have to be broken in order to move the object, especially with initial movement, when static friction is preventing the object from moving. For example, it would be much easier to move a light cardboard box than a heavy steel block, and it would be much easier to move both objects on a path of ice than on grass.
