Question

what is mean by friction ​

Answer 1

Answer:

the resistance that one surface or object encounters when moving over another.

Answer 2

Answer:

what is mean by friction?

Explanation:

==>The rubbing of one surface or things against another.

==> There are four types of friction are there:-

•rolling friction.

•sliding friction.

•static friction.

•fluid friction.

The rolling friction:-

==>The force resisting the motion of the rolling body on a surface is known as the rolling friction or rolling resistance.

==>Rolling of a ball or wheel on the ground is the example of rolling friction.

Sliding friction:-

==>The sliding friction is also known as kinetic friction.

==>The friction between two bodies that are in sliding friction.

==>sliding friction comes to play whenever an object moves along the surface of another object, such a movement is called 'slide'.

==>Hence, the sliding friction is the force that opposes the movement or slide of an object.

Static friction:-

==>The static friction is the force that keeps an object at rest.

==>static friction is the friction between two or more solid objects that are not moving relative to each other.

Fluid friction:-

==>Fluid friction occurs between fluid layers that are moving relative to each other.

==>The example of fluid friction are riding a bike.
