Practicing conversions

Drawing on algebra and trigonometry

This chapter gets the ball rolling by discussing some fundamental physics measurements. At its root, physics is all about making measurements (and using those measurements as the basis of predictions), so it’s the perfect place to start! As you go through the process of converting measurements from one unit to another, you’ll practice applying math skills to physics problems.

Measuring the Universe

A great deal of physics has to do with making measurements — that’s the way all physics gets started. For that reason, physics uses a number of measurement systems, such as the CGS (centimeter-gram-second) system and the MKS (meter-kilogram-second) system. You also use the standard English system of inches and feet and so on — that’s the FPI (foot-pound-inch) system.

In physics, most measurements have units, such as meters or seconds. For example, when you measure how far and how fast a hockey puck slid, you need to measure both the distance in centimeters and the time in seconds.

For reference, Table 1-1 gives you ...
