The phrase usually used for this is "reference frame".
frame of reference
Motion is always relative to something. There's no such thing as really "stationary."Stationary only means that the motion of the observed object matches the observer's motion. Example: Reading the book that lies 'stationary' in your lap while you're in a car or on a passenger jet.
stationary friction is when friction is happening on an object that is stationary.(STATIONARY MEANS STAYS STILL, OR NO MOVEMENT)
A group of forces that is balanced ... that is, forces whose vector sum is zero ... has no effect on the motion of an object, whether the object is stationary or in motion. However, they may crush the object.
It means that the object is moving.
If acceleration means to increase in speed or pace, then a stationary object is static, without movement, without acceleration. But, if an object is moving at a constant rate, then I suggest acceleration is not present, unless, or until the objects speed increases. Yes, an object with no acceleration may be stationary.

vibratory means stationary with no motion, oscillatory means with uniform motion like pendulam.

An antonym means the opposite. A satellite is an orbiting object. The opposite of that would be a stationary object.

Relative motion. To talk about a train moving at a certain speed usually means that the train is moving at a certain speed relative to a stationary observer (relative to the ground). This however also means that a passenger traveling in said train would experience the ground (and every other stationary object) as the moving object. This is why a stationary train may seem to be moving to passengers of an already moving train.
It means that the object is moving.
Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.
Newton's First Law of Motion states that an object remains at a constant velocity unless it has an unbalanced force acting upon it. That constant velocity includes zero, which means that a stationary object with no force applied to it will not move. Since velocity includes direction, then a moving object with no force applied to it will continue to move in a straight line at a constant speed.That tendency is called inertia.
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
