Units and Dimensional Analysis

You need a Java-capable browser such as Netscape 2 for Windows or Netscape 3 for Macintosh to be able to work with the units problems.

Your goal is to find the correct expression for the given variable. Click on a variable, then click on the "Numerator" button to put one factor of it in the numerator (and similarly for the denominator). The collective SI units will be displayed.

Dimensionless factors (ie., 1/2) are ignored. There is often more than one correct answer - see if you can find them all!
