What is friction?

Friction is defined as a force that resists the sliding or rolling of one solid object over another.

• It is the resistance offered by the surfaces that are in contact when they move past each other.
• Frictional forces like 'traction' needed to walk without slipping, may be beneficial though they also present a great measure of opposition to motion.
• The major cause of friction between metals caused by the forces of attraction which is known as adhesion.
• Adhesion works between the contact regions of the surfaces, which are always microscopically irregular.
