Question

which three factors most affect friction?
temperature
volume
texture
surface area
density
mass

Explanation:

Friction is affected by the texture of surfaces in contact (rougher textures generally increase friction), the surface - area in contact (in some cases, more surface area can mean more friction), and the mass which affects the normal force pressing the surfaces together (more mass usually leads to more friction). Temperature, volume, density have less direct impact on friction in most common scenarios.

Answer:

C. texture, D. surface area, F. mass
