DIVA Overview

Problems come from Physics by Wolfson and Pasachoff, 3rd Edition. The problems fall into three categories:

 

How to Use DIVA

The purpose of DIVA is to provide students with examples of expert problem solvers. These examples will be most useful to students who have familiarized themselves with the problems before they look at the written solutions or watch the movies
