your question is a but vague.
the answer refers to the Newtonian aspect of it:
if you have a reference point, then you can measure the difference between the two places of that object.
taking time into account, you can derive its velocity and acceleration rate.

Motion is important because it helps us define if were moving or not. With out motion we couldn't be able to move.An object is in motion if its position changes it relative to another object.
I think it's important to know if your reference point moves because your reference point is the object that's not supposed to move and if it moves it will mess up your hypothesis of thinking that your 1st object moves. It takes a while to completely understand the answer, or even the question
yes, if the speed is negative, that is, moving backward
Deciding if an object is moving isn't as easy as it sounds. We can only discern relative motion and we have to use reference points. (A reference point is an object that is not moving that you compare to the other object.) An object is in motion when it's distance from the reference point is changing.For example, you could say that you and this computer are not moving. Other than your eyes blinking, chest pumping up and down, and you clicking on the mouse, you and this computer are not in motion. Since the distance between you and the computer is not changing, you can conclude that neither you or the computer are moving.
No, an object not moving relative to Earth is not a blue shifted object. With no relative motion, an object will not be subject to Doppler effect and will not red or blue shift. For an object to be blue shifted, the distance between the object and Earth must be decreasing. The object must be closing on Earth or vice versa.
motion occurs when an object changes its position relative to a reference point.
DisplacementMotion
Its position changes relative to a frame of reference.

the answer is motionAn angle.DisplacementMotion is a change in the position of an object in relation to a reference point.
An object is in motion if it changes position relative to a reference point. Motion is a relative quantity and is expressed in respect to the position of another object. Example: both a car and the Earth are moving (earth is revolving around the sun) but if we express the motion of the car in respect to the Earth, we say the car is moving relative to the Earth. At the same time the earth is moving relative to the sun.
Its position, relative to the point of reference.
A change in an objects position relative to a reference point is called motion.
motion
motion
the object is moving relative to that point.
