Momentum can also be applied to objects that are rotating or that have a torque acting upon them. When you solve for linear momentum in any question, be consistent with the direction you choose to be negative.
For example, if you choose to make downwards negative, keep that direction negative throughout the problem. It sounds daunting, but there are tons of great resources available to help students succeed in these endeavors. Besides reading the textbook, a skill which is difficult to master yet extremely valuable, a review of the key material distilled down into a clean easy-to-understand format can be invaluable. I have been teaching online courses with the use of video since , so please let me be clear, I absolutely do not believe in passive instruction by video.
A little bit of me dies inside everytime I read about classes in which students are placed in front of a computer as the sole means of instruction. Besides being ineffective, how boring! Physics is supposed to be fun, and I have trouble imagining how students can make it through such lonely, soulless courses. I do, however, believe that supplemental on-demand video lessons taught by strong instructors such as those at Educator.
Undertaking learning through inquiry and modeling can be messy and confusing. Having an online instructor there to assist in cleaning things up or explaining things in a different manner or from an alternate perspective can make a world of difference.
Here are all the courses that I teach on Educator. Further, review books such as AP Physics 1 Essentials are designed to assist in these stages of learning, not as a replacement for the oh-so-valuable active learning experiences, but rather as an easily accessible means of solidifying the basic relationships and concepts.
I wrote AP1 Essentials to help students understand essential physical relationships in a manner that is straightforward and easy-to-read, leaving development of in-depth problem solving and lab work for the classroom, where they are most effective. Instead, the goal for this book was to create a resource that students would actually read and enjoy, and help them along their path to a deeper conceptual understanding.
Instead, these new courses are comprehensive learning experiences combining exploration, experimentation, application, and communication skills. Only by putting in the effort and struggling through the frustrations will students find their way to mastery of the course.
