Which best describes friction int the context of newtons laws? 1.a kind of tape that holds things together 2.the force that opposes the relative motion of two objects in contact with and sliding past each other 3.a force that is always in the direction opposite to the acceleration 4.an objects resistance to being accelerated by a force

2. the force that opposes the relative motion of two objects in contact with and sliding past each other

Explanation:

Consider a body supported on a horizontal and rigid surface. If the body receives the action of a force f, due to the roughness, the frictional force appears.

Frictional forces are contrary to movement. There are two types of static and kinetic friction. When there is force acting on a body but it does not move, friction is called static, when there is force acting on a body and it moves, friction is called kinetic. In general, we can say that friction is the force that opposes the relative movement of two objects in contact and sliding one after the other.
