the type of surface and the weight of the object

Explanation: friction ≈ μN, so it depends on the surface material/roughness (μ) and the normal force (N), which for a horizontal surface is the object's weight. An applied push only indirectly affects friction by changing whether the object is at rest (static friction up to a limit) or moving (kinetic friction); a push with a vertical component can also change the normal force.
