displacement
The change in an objects position is called motion.
In the question, "an object's change in position...over...time" is a perfectly reasonable definition of velocity.
movement
Motion
Speed --- actually, if your question is 'position' over time, there is no answer since position is a vector quantity. And position divided by time will still yield a vector quantity-- velocity. If the question asks for change in distance over time, then the answer is speed. --gh ---

The rate of change of an object's position over time is the object's speed.

Change in position over time is velocity ("speed").
Displacement is the change in position of an object. The equation for displacement is Δd = df - di , where Δd is change in position (which is displacement), df is final position, and di is initial position.
The push or pull action or force on an object causes change in position of an object
Velocity is change in position, or displacement, over time.
The force that can change an object's position is an unbalanced force.
The change in position of an object compared to a reference point(another object) is called motion.
