Question

Define Force of friction. List the factors affecting the force of friction. Explain
with examples.​

Answer 1

Explanation:

The friction force is the force

exerted by a surface as an object moves across it or makes an effort to move across it.

The factors affecting friction are:-

1)The weight of the object

2)The type of the contact between the two surfaces. Example - Skiing

Answer 2

Explanation:

The force of friction always opposes the motion of an object ,wheter the object is moving or at rest...(this is the definition for the friction of force)

Factors affecting friction:

*A rough surface has more irregularities than a smooth surface that is why the force of friction is usually greater between rough surface then it is between smooth surfaces.

*another factor that affects friction is the force of attraction between some atoms on the two surfaces which has to be overcome..

*third factor affecting friction is the force exerted by the object . The greater the force the greater the friction.

Example: due to the third factor this is why it is more difficult to move a heavy table than a light table...
