Question

List three ways of reducing friction?give examples for each

Answer 1

use lubrication , reducing contact area,

Answer 2

The most common methods used to reduce friction between moving surfaces include polishing the surfaces that come into contact, lubricating the surfaces, using ball or roller bearings and streamlining. Friction is defined as the force that resists one surface from sliding or rolling against another surface. This means that friction is only present when one or both of the surfaces that are in contact are in motion.
