The content matched what was in the book, "Stop Faking It" Force and Motion by William Robertson. I thought that a lot of the explanations were worded well enough to understand if you stop and think about how Newton's laws apply around you. Very often, I found myself doing the demonstrations just because they were so practical and easy to perform.

Informative and well illustrated.
The progression through the material had an easy flow. I really appreciated the diagrams and interactives throughout the descriptions.
There was also a lot of interesting questions that were posed in the beginning that I could use in my own classroom.
