I am going to tutor a high school student. I had an initial meeting with him and learned that he is using Conceptual Physics by Paul Hewitt. During the initial consultation, the student had a few questions to ask. It was a typical problem where a mass on the table is attached to a string. The string passes over a pulley at the edge of the table. The other end of the string is attached to a hanging mass. Question is to find the acceleration of the masses. My immediate approach was to use Newton's second law to both masses and solve for acceleration. But the student has never learned how to draw force diagrams. He did not know about the tension on the string. This is my first experience with a high school student although I have college teaching experience. Is there any other approach to this problem? Also, do you have any advice as to how to help high school students to learn and like physics? In two weeks, the boy has his mid-term test and he needs my help. Thank you for any suggestions and advice. Gamma.
