Welcome to Physics

If this is your first IUHS 'Independent' course, welcome! If you have experienced this type of learning before, I hope it was a rewarding one. Science 22P is an introduction to the study of physical science with an emphasis in the area of physics. Whether you have an aptitude for science or not, I hope you will enjoy and be enlightened by this brief overview of physics.

IUHS Independent courses require you to read, search, and learn independently. It is important that you be aware that reading the discussion section is a key part of each lesson. Be sure to contact your instructor and ask questions about any items or topics in the discussion that were difficult for you. This practice will allow your instructor to better understand any problems you may be having. It will also allow you to gain a better understanding of the course.

This course is an introduction to physics and will introduce you to topics that would be part of a more in-depth study in a course of beginning physics. Physical science does require basic mathematics in explanation of some phenomena, for conversions in the metric system, and in the solution of simple equations.

Physics is the most basic of the natural sciences. It is the study of mass and energy. It is about motion, energy, forces, sound, light, magnetism, electricity, and mechanics. Other natural sciences, such as chemistry and biology, build on some of the principles of physics. By knowing the laws of physics, you can better understand the other natural sciences. Engineers, athletes and coaches, automotive mechanics, and medical technicians are professions that depend heavily on a knowledge of physics.

By studying this introduction to physics, you should gain a much better understanding of many everyday experiences that involve motion, sound, electricity, and heat.
