Friction: Disadvantages and Examples
Friction is crucial for daily activities, yet it does have disadvantages. One major drawback of friction is the wearing out of shoe soles. When walking or running, the friction between the ground and shoe soles causes them to gradually deteriorate, necessitating repairs or replacements.
For instance, running on the ground leads to continual friction between the shoes and the ground, resulting in wear and tear. Another example is when lighting a matchstick, where friction is employed to ignite the match, but this process also wears down the matchstick due to the abrasive nature of friction.
