Answer:
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.
DISADVANTAGES:
Friction produces heat which damages the moving parts of a machine.
Friction produces heat which damages the moving parts of a machine.Friction produces wear and tear on the contacting surfaces. This reduces the life of machine parts, tyres and shoe soles.
