The book slides with constant velocity.
When the velocity changes. And the velocity will change when the forces on an object change. For instance, some types of friction forces change as a function of velocity.
the INITIAL velocity does not change. It is constant. however, the velocity changes depends on the friction and inclination of the inclined plane.
force
When there is any change in its location. In an imaginary scenario where there is no friction, it is when there is a change in its velocity.
None. Change your question for two OBJECTS and the answer is friction.
Acceleration is the rate of change in velocity. It has nothing to do with friction, unless friction is causing the change.
The materials that, in general, change sliding friction to fluid friction are called lubricants. This class of materials includes oil, grease and the like.
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.
