General Physics I Course Text

● This course does not require a text. Course Description This course will start with a descriptive approach. You will first learn about kinematics-the branch of mechanics that describes motion. From mechanics you’ll move to the study of energy, power, and momentum. These concepts will be defined rigorously. You’ll learn how Newton’s laws need to be modified in order to avoid limitations: a few new and simple ideas introduced by Einstein. To conclude you’ll learn about Heat and Thermodynamics, including the 1st and 2nd Law of Thermodynamics. This course requires knowledge of basic algebra, trigonometry, and elementary calculus.

Course Objectives

After completing this course, students will be able to: ● understand the basic principles pertaining to Newtonian mechanics ● apply these principles to solve practical problems in these areas of study

Course Prerequisites

StraighterLine does not require prerequisites, however it is suggested that students have finished Calculus I (MAT250) prior to enrolling to ensure the best possible outcome. Important Terms In this course, different terms are used to designate tasks: ● Exam: A graded online test. ● Exercises: ungraded practice exercises and quiz questions.
