Question

1)what is friction?
2)Define static friction?
3)what is sliding friction? ​

Answer 1

Answer:

1) what is friction?

➡️Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

2) Define static friction?

➡️Static friction is a force that keeps an object at rest. The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface which it is on.

3) what is sliding friction?

➡️Sliding Friction comes into play whenever an object moves along the surface of another object. Such a movement is called 'slide'. Hence, sliding Friction is the force that opposes the movement or slide of an object.

Answer 2

Answer:

$\huge{\underline{\underline{\sf{\pink{Answer}}}}}$

➞What is friction?

A force which acts at the surfaces of contact, when one body moves upon another body is called force of friction.

➞What are the types of friction?

There are three types of friction:

✦Static Friction:

The frictional force that comes into play when one body tends to move over the surface of another, but the actual motion has not started yet is called static friction.

✦Rolling Friction:

The frictional force that comes into play when one body is actually rolling over the surface of another body is called rolling friction.

✦Sliding Friction:

The frictional force that comes into play when one body is actually Sliding over the surface of another body is called sliding friction.

➞ Explain Friction as a boon and friction as a curse.

Force of friction brings about wear and tear in moving bodies. It produces heat and slows down a moving body. A lot of energy is wasted in overcoming friction.

However, if there were no friction, the bodies will either slip or not move. Furthermore, the bodies will not stop. Even walking on the surface of the Earth would have been impossible. Thus, we can say that friction is a necessary evil.
