PhysicsTutor Excalibur is a complete, interactive physics tutorial on CD that covers the full physics curriculum from high school physics through the first two semesters of college physics. PhysicsTutor Excalibur teaches physics using a unique, time-saving approach that students really like. PhysicsTutor Excalibur teaches each of the concepts of physics by way of example. This puts each concept into context for a student and makes the concepts easier to understand. Students find this approach much more understandable than the approach that most textbooks take in which concepts are explained in only abstract terms.   Here is how PhysicsTutor Excalibur works: 1. First, it breaks down the study of physics into 20 manageable subject areas. 2. When you select a tutorial in one of these 20 subject areas, PhysicsTutor Excalibur displays a question that you will need to be able to answer once you have mastered that subject area of physics.  If you already understand how to solve that type of problem, you can go ahead and answer it.  However, if you have no idea how to answer that question, you can click on the LEARN button.  3. This will bring up a screen that explains the concept associated with that question and shows you how to, in general, approach that type of question. 4. Then try to answer the question.  If you still have difficulty with the question, click on the EXPLANATION button. 5. This will bring up a screen that shows you, in detail, how to solve that specific problem. 6. After you have correctly answered a question, click on the NEXT QUESTION button. 7. Depending on the difficulty of the concept, this will either display another similar question associated with that same concept or a new question that is associated with another concept in that subject area. Compared to reading a traditional physics textbook, PhysicsTutor Excalibur is a much more efficient and effective way to learn physics.
