How is friction harmful? ›

Below is a list of friction's negative impacts: A lot of heat is generated by friction in various mechanical parts, which wastes energy as heat. Restricts motion, requiring more energy to overcome it. Making noise while operating a machine wastes energy and is annoying.

Since friction is a resistive force that slows down or prevents motion, it can be a nuisance, because it can hinder motion and cause the need for expending extra energy. Friction can also cause parts in contact to heat up and can cause parts in contact to wear out.

Friction comes into play when two irregular surfaces come in contact. The continuous rubbing of these surfaces together causes it to gradually wear out. Also, much of the applied force or energy is wasted in overcoming the force of friction. Hence, it is considered as evil, but it is necessary too.

Friction is very useful for us otherwise we will all be slipping and sliding, bumping, tumbling, rolling all the time.. Friction help us in that manner, holding us up and steady, stationary whenever we want to… Friction is also harmful since it will also stop us from doing things that needs to be done…

Because of the friction, the machine parts will wear out. Because the frictional force resists a body's motion, it takes more energy to overcome the friction. Forest fires are caused by friction between the branches and leaves of trees. Unwanted noise is produced by friction between machine components.

Friction is an evil that hampers the motion, causes wear and tear in machine parts, and causes wastage of energy, but the same friction is very necessary for us as is clear from the explanation provided below: Friction between our feet and the surface enables us to walk.

Final Answer:

c) Engine parts wearing out due to friction is a classic example of harmful friction, leading to reduced efficiency and the need for frequent maintenance and replacements in machinery and engines.
