Course Description

Mechanics is the study of motion. This course focusses on the classical theory of motion as understood using Newton's laws, dividing the material into three broad subjects. In the first part of the course, the student is introduced to basic kinematics (the description of how things move) with an overview of motion concepts and a couple of simple examples: motion with constant velocity and motion with constant acceleration (especially projectile motion and circular motion). The course continues with a study of dynamics (the explanation of why things move) and an exploration of several common types of force: gravity, string tension, friction, drag and (introducing Newton's third law) thrust. The final part of the course involves the study of conservation laws -- especially in their relation to momentum, energy and mechanical work -- and how they facilitate the study of motion. Instruction concentrates on basic principles of physics and general problem-solving techniques, both in class and in web-based homework assignments.

The lectures follow the first 11 chapters of the textbook (Randall Knight, Physics for Scientists and Engineers), in order. Weekly homework assignments are hosted by Pearson Education's Mastering Physics online homework system. There are three exams. A laboratory section is also associated with the course, with a 2-hour lab every other week. The labs are managed separately from the lecture course, but contribute to one course grade at the end of the semester. See the "Labs" sidebar link for details.
