That is equivalent to saying that:* The object moves, or
* The object's position changes over time
when can you say that the object is in motion
You would say that the object in motion is accelerating. Or you can say that the object's velocity is increasing.
It means that the object is moving.
Stationary reference points are chosen to determine an object's motion because they provide a frame of reference that is not moving and can be used as a benchmark for measuring the object's motion relative to it. This helps in accurately defining the object's position, speed, and direction of motion.
An object in motion will stay in motion, at a constant velocity. This assumes that no net force acts on the object. This is known as Newton's First Law.

"un objet" (masc.)
An object is considered to be in motion when its position changes with respect to a reference point over a period of time. The object's motion can be described in terms of its speed, direction, and acceleration.
In order for an object to be in constant uniform motion ... that is, un-accelerated, with constant speed and direction of motion ... the vector sum of all forces acting on it must be zero.
That is equivalent to saying that: * The object is moving, or * The object doesn't stay all the time in the same place.
