Friction

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.

ways to reduce friction?

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings

Answer 2

Answer:

Friction is the force that opposes the motion of a body.

Two ways to reduce friction are

using oils i.e. lubrication of surfaces

making the surfaces smoother
