Dual-Enrollment Course Outline - Accelerated Physics Instructor: Mrs. Terri Ogden Email: togden@pomounties.org Course Goals Accelerated physics is an introductory course designed to teach the basics of physics. This course will cover linear and projectile motion, inertia, forces, energy, friction, waves, sound and electricity. Be prepared to apply trigonometric concepts as well as use algebra skills fluently. Mathematics is the language of physics and helps to define it. Other topics may be covered, time permitting, such as optics, magnetism, thermodynamics, and students’ interest. Welcome to the science of energy! Materials Textbook: Serway, R.A. & Faughn, J.S. (1999). Holt Physics. Holt, Rinehart, and Winston: Austin, TX. Supplemental materials such as notes, study guides, readings, et cetera will be provided. Students are responsible to obtain a scientific calculator (two line display preferred), notebook, and writing utensils. Students may also want to keep a 3-ring binder to organize important worksheets.
