Final answer:
Friction on a solid surface is influenced by surface type, object weight, and normal force.
Explanation:
The factors that can affect the amount of friction acting on an object on a solid surface are:
- The type of surface: Different surfaces have different levels of roughness and materials, affecting the amount of friction generated.
- The weight of the object: The force of friction is influenced by the weight of the object pressing down on the surface.
- The normal force: The normal force between the two surfaces impacts the friction between them.
