An important skill in physics that is used often is unit conversions.
Below is a list of the units from the order of magnitude of 18 to -18.

                       Unit Analysis

Equations are used often in physics, and it is important to
manipulate the UNITS in the equation as well at the numbers.
The below examples provide some practice in this skill. This
skill will be used throughout the course. (see page. 772)

Ex.1 Velocity x Time




Ex. 2 Force / Acceleration




Ex. 3 Mass2 x Speed
