Question

How is friction harmful?

Answer 1

Hint:Friction is the force exerted by two surfaces moving (or attempting to slide) over one another. When you try to push a book across the floor, for example, friction makes it harder. Friction always acts in the opposite direction from where the item is going or attempting to move. A moving item is always slowed by friction.

Complete answer:
When two uneven surfaces come into touch, friction is created. It eventually wears down due to the constant rubbing of these surfaces together. Furthermore, overcoming the force of friction wastes a large portion of the supplied force or energy. As a result, it is regarded as wicked, yet it is also essential.

Friction slows the speed of moving things and can even bring them to a complete stop. Heat is produced by friction between the items. As a result, energy is wasted in the machinery. 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. It generates heat, which may be used to warm sections of an item or ourselves. It also results in a loss of power. During any operation, it generates noise. We are able to walk, run, play, and so forth due to friction.

Note:Because there is less interlocking between smooth surfaces when two smooth surfaces are in touch, the degree of friction between them is low. When two rough surfaces come into contact, the degree of friction between them is high due to the excessive interlocking of rough surfaces. It is also affected by the object's weight or the amount of force it exerts on the surface.
