WebHow is friction harmful? Solution 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. WebMay 16, 2024 · This phenomenon, which is responsible for stopping objects in motion, is known as friction. It generally acts in the opposite direction with respect to the direction of motion. Friction – Friction is the force, which resists the relative motion of surfaces or bodies sliding against each other.
