Course Description




 
Physics is a foundational science on which many of the concepts of chemistry, geology, biology, and otheratural sciences rely. Because physics is a math-intensive subject, it is sometimes intimidating to those who wish to study it.
 
This course focuses on some of the critical mathematical tools required for studying physics and is geared toward students with a basic knowledge of algebra, geometry, and trigonometry. Starting with an introduction to vectors, the course then begins to develop a set of mathematical tools for studying classical Newtonian mechanics as well as some basic topics in classical electromagnetism. Although the course does not cover calculus, the math that is presented is more than sufficient for analyzing and solving a wide range of problems involving the motion of objects and forces such as gravity, the electric force, and magnetism.
 
The first half of the course deals with objects in motion, including how to quantify and relate characteristics such as force, velocity, momentum, energy, and power. The second half of the course focuses on waves and electromagnetism, starting with a look at the electric and magnetic forces and their sources, then moving to acoustic and electromagnetic waves, and ending with an overview of geometrical optics. By the end of the course, students should be armed with many of the tools they need to study physics in depth.
