Alta High Conceptual Physics What is Mechanics The study of how and why objects move  is called  Mechanics. Mechanics is customarily divided into 2  parts  kinematics  and  dynamics . We will begin with the simplest part of  kinematics – motion in a straight line.   This is know as  linear  or  translational  motion.

Alta High Conceptual Physics Frame of Reference In physics, Motion is relative.  This  means that in order to describe motion,  you have to pick a “frame of reference” Frame of reference is always decided by  the observer In physics we often use a  coordinate axis   to denote our frame of reference.
