What condition will tend to prevent an object to move?

Friction, physical barriers, energy fields (such as magnetism), etc... Come to mind but I'm not sure if this question is as general as it is worded. A specific condition would be encasement in ice but there would be infinite answers if you are asking specifically.

As everything is relative, inertia will tend to prevent a change, which looks like preventing an object from moving.

Well, movement is relative to a specific reference point.

Gravity is the cause of friction.  Friction is typically the major counter- force found on earth to oppose motion.
