The simple but informative cover on this title will quickly find an audience for this book with those teaching the physics of roller coasters as well as with young roller coaster enthusiasts. The work does a reasonable job of explaining basic concepts at work including force, friction and kinetic energy to students and provides a simple hands-on project to explore the covered ideas using easily acquired materials. This is a can't miss activity that will be enjoyed over and over again. A safety warning is needed in the construction directions for those students who may be attempting this project on their own. A diagram could be more clearly labeled to aid in its helpfulness but otherwise, it will be a useful resource for those interested in elementary physics.
