Material Detail

I spent something over an hour exploring this material, and highly recommend it.
This collection of problems, though useful in themselves, are perhaps even
more useful as examples and/or templates for instructor-customized physlet
problems. Most are of excellent quality. Both qualitative and quantitative
problems are included within the set. Some are rather difficult, and will
provide a challenge for very good students. Others should be accessible to all
students in an introductory course who take the time to think about them. Most
probe student understanding in ways not accessible to typical end-of-chapter
problems. Some work will need to be done by instructors to modify these (e.g.,
remove the answers, put randomness in the problems) if they are to be useful for
graded homework, although they can be used as is for study self-study beyond
the basic in-class presentation.
