Unit 2: Motion in a Straight Line
Our formal study of physics begins with kinematics, which is defined as the study of motion without considering its causes. The word "kinematics” comes from a Greek term meaning "motion.” In this unit, we will study motion without worrying about what forces cause or change it. Such considerations come in later units. In this unit, we will examine the simplest type of motion - namely, motion along a straight line, or one-dimensional motion.
Completing this unit should take you approximately 13 hours.
