What are 2 factors that determine the amount of friction between 2 objects?

• Force and roughness between surfaces

• hills and valleys and how smooth or rough the surface is

• Amount of force and amount of surface the comes in contact

• The force and the weight exerted on the surfaces

Without friction, an object in motion would never stop.

• true

• false
