Chapter 13
In order to understand how machines work, it is important to have a good grasp of applied physics. The study of applied physics is the study of the practical application of the laws of physics. Engineering, architecture, and heavy equipment operation depend upon applied physics. This chapter will build on concepts first discussed in the Physical Science portion of chapter 9: General Science to explain how various common mechanical devices operate.
