Course Overview

Kinematics is the branch of physics that describes motion without considering the forces that cause it. In this course, students will learn how physicists measure, describe, analyze, and predict motion using mathematical models, graphs, and equations. Beginning with the basic concepts of distance, displacement, speed, and velocity, students will progress through acceleration, motion graphs, equations of motion, and two-dimensional motion. By the end of the course, students will be able to analyze a wide variety of real-world motion scenarios and solve problems using the tools of kinematics.
