Question

1• What is friction ? Explain the different kinds of friction.2 Explain the desirable and undesirable factors of friction3.Give examples of push or pull.4 Give examples of change in speed, direction with the application of force on object​

Answer 1

Answer:

Friction is defined as the force that opposes the motion of a solid object over another. There are mainly four types of friction: static friction, sliding friction, rolling friction, and fluid friction. ... If we consider only the rotational motion, then point B tends to move backwards suppose with a velocity VR

Answer 2

Explanation:

Friction is a kind of force a sliding force .It generates when two objects move away from each other in two opposite directioon or in rest .

There are two kinds of friction

static friction is generated when two are not in motion

Knetic friction generates when two objects are in motion
