Which force causes a heavy appliance to resist movement when being pushed?

Magnetism is a force that arises between magnetic materials and affects their motion and interaction primarily through attraction or repulsion. While it can influence certain objects, it does not play a role in the resistance to movement of a heavy appliance on a surface, which is primarily governed by friction.

Gravity is the force that pulls objects toward the Earth, contributing to the weight of the appliance. Although it affects how much friction force is present (as heavier objects exert more force against the surface), gravity itself does not directly cause the resistance to movement; that role is filled by friction.

Tension is a force that is transmitted through a string, rope, or cable when it is pulled tight. It is not applicable in the context of resisting the movement of a heavy appliance being pushed across a surface, as tension typically relates to forces in strings or cords rather than direct contact forces like friction.
