The opposite force to friction is momentum. Because friction stops an object from moving or slows an object down, momentum keeps it at speed.
Friction
The resistance force that always opposes motion is friction. Friction is the force that acts between two surfaces in contact and it opposes the relative motion between the surfaces.

The force that opposes motion when moving objects over a surface is called friction
the force that opposes the motion of two touching surfaces is velocity.
Friction is the force that opposes motion between two objects.
Static friction is the type of friction that opposes the motion.
Friction is a force that always opposes the motion of an object. It occurs when two surfaces are in contact and resists the relative motion between them.
Friction, I think
Frictional force is a contact force which opposes relative motion.
