Final answer:
The potential energy for friction when dragging a table depends on the coefficient of friction, normal force, and distance.
Step-by-step explanation:
The potential energy for friction when dragging a table across a rough floor depends on the coefficient of friction, the normal force, and the distance the table is dragged.
The coefficient of friction is a unitless quantity that depends on the two surfaces in contact. It determines the amount of friction between the table and the floor.
The normal force is the force exerted by the floor on the table perpendicular to the floor. It is equal to the weight of the table.
The distance the table is dragged affects the work done against friction, which is the product of the force of friction and the distance.
