Firstly let's learn, what does Friction means.

↬Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

10 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)

• Lubricants(oil/grease)

• Not related to the area of contact

• Friction is more on rough surface
