Want this question answered?
motion
a body is said to be at rest if it does not change its position relative to a reference frame similarly a body is said to be in motion if it changes its position relative to any reference frame.
Displacement
The answer is motion
false
A change in an objects position relative to a reference point is called motion.
A change in an objects position relative to a reference point is called motion.
A change in an objects position relative to a reference point is called motion.

the answer is motionAn angle.DisplacementMotion is a change in the position of an object in relation to a reference point.
It is the process of a change in position relative to some fixed point of reference.
In the question, "an object's change in position...over...time" is a perfectly reasonable definition of velocity.
If we're in the realm of newtonian physics I would say that it couldn't be in motion relative to a reference point, of course quantum physics and seems to prove everything we believe wrong.
