positive and negative

Answer 2

The terms positive and negative can be useful when giving opposite directions from a reference point.

• Positive and negative terms are answers of the given blank.

• A reference point is a place or thing which used for contrast to determine if something is in motion.  

• An object is in motion if it varies a position in relation to a reference point. Objects that are fixed relative to Earth – for example, a building, a tree, or a sign - make respectable reference points.
