Professor Fran Bagenal at the University of Colorado has some great astronomy resources, including this page on Universal Motions. In addition, there are some very clear and useful diagrams that go along with her notes. I like to use her diagram of a rocket for my own lesson, but many of hers could be useful in any of these Newton lessons.
