Question

a. What are the factors that affect friction?​

Answer 1

Explanation:

What are the factors affecting friction?

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)
