Physics is the science which explores matter and energy in terms of motion and force. While Algebra 1 is a prerequisite for the course and solving problems involving mathematical computation is required, the focus of this course is on understanding concepts, rather than on numerical manipulation. Everyday examples and illustrations are used wherever possible, and students are encouraged to think through specific applications of the general concepts which they study. In completing this subject, among other activities, students apply the concepts they have learned to explain the physics of actual situations. There are 11 examinations in Physics.
