The force that opposes motion of a surface as it moves across another surface is friction.
Friction
gravity
Friction opposes the motion of one object moving past another. Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a force acts on them.

There are many types of forces that oppose motion such as friction, drag and most universal, gravity.
