Reading Assignment: Chapter 2, Sections 2-10 Introduction: The study of motion is broken into two main areas of study – kinematics and dynamics. Kinematics is the description of how objects move. Dynamics is the description of why objects move. It is important to understand how an object moves before exploring why . Therefore, the first labs in this course focus upon the study of kinematics. In particular, this study involves the relationships between the quantities of position, distance, displacement, speed, velocity, acceleration, and time. These relationships are conceptual, mathematical, and graphical. Thorough understanding of kinematics requires knowledge of each of these types of relationships.

For example, much of the excitement in riding a roller coaster arises from the high speeds and accelerations experienced during the ride. Although motion often occurs in more than one dimension, it can be simplified by considering one dimension at a time. Motion in one dimension is any motion that occurs along a straight line. Notice that one dimension has two directions. Therefore, positive and negative values of position, velocity, and acceleration have particular meaning. Several types of motion in one dimension occur commonly in a wide variety of physical circumstances: objects at rest , objects in motion with constant velocity , and objects in motion with an acceleration that is constant and parallel to the direction of motion . Motion under the influence of gravity close to the earth's surface and motion under the influence of a constant force are the two most familiar examples of motion with a constant acceleration. Remember that all motion is measured from a particular origin or reference frame. © 2004 Penn State University
