—Motion is the phenomenon in which an object changes its position over time.
2.E
—A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign - make good reference points.
3.A
—Distance is a numerical measurement of how far apart objects or points are.
4.B
—A vector contains two types of information: a magnitude and a direction. The magnitude is the length of the vector while the direction tells us which way the vector points. Vector direction can be given in various forms, but is most commonly denoted in degrees. Acceleration and velocity are examples of vectors
5.D
—displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.
