How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed

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
