does the nature of the surface affect frictional force ? explain.
how do the lubricants or water or oil reduce the friction of the surface ?
plz frnd answer it's urgent?
1st answer will be mark as brainliest
Answers
2 - lubricants or oils make the surface smooth which make the force decrease and thus we apply lubricants and oils
Answer:
Frictional force actually reduces the relative motion of a body. Various factors which affect friction are: Smoothness of surface:-more the surface is smooth, less is the friction.
How does the nature of the surface affect friction?
Why does the type of surface affect friction? ... Another factor for friction is electrostatic interactions between the atoms in each object. If an object is too smooth friction can actually increase because these interactions increase as well. To a point, friction is independent of contact surface area.
How does lubrication reduce friction?
A lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces
Why does oil reduce friction between surfaces?
A: To reduce friction, oil is added to the engine. The oil coats the surfaces of the moving parts and makes them slippery. They slide over each other more easily, so there is less friction.
