Answer 1

Explanation:

(i) Roughness or smoothness of the surface

(ii) Type of friction (sliding or rolling)

Answer 2

Question:

write two factors that affect friction...

Answer:

• Roughness/smoothness of the sliding object.

• Roughness/smoothness of the surface.

• Shape/design of the object.

• Normal force acting upon the sliding bodies.

• Dry friction is independent of the surface area of a contact.

• Type of friction involved(rolling/sliding)

• Sliding surface's state of matter (solid/fluid)
