Recent Tutoring Session Reviews
"The student has a test on Monday that focuses on the concept of electric energy and electric potential. In order to prepare for the test, she wanted to complete the review sheet her teacher had given her together. It was a multiple choice worksheet that focused on these topics. She did very well with the worksheet and was able to complete almost all of the problems without my help. I did need to help clarify a few topics, including the difference between electric potential and electric potential energy. She wanted to meet again on 3/8 to complete extra practice problems in the book."
"To help prepare the student for her physics test on Monday, we reviewed textbook problems covering Work and Energy. She's able to do those problems by making proper use of the equations such as W=Fd and W=Delta E when calculating work. Also, she's able to set up the Conservation of Energy equation based off of the information that the problems give, and then solve for whatever the problem is asking (i.e. velocity)."
"Today we spent the majority of our session working on the concepts of electrostatics. We went over the fundamentals of charge, electric field force, and point charges. We worked mainly with the concepts and completed our session working out a few problems involving the forces generated between point charges."
"We went through this session in a similar manner to our previous sessions. This time, we covered electromagnetic optics and images (chapters 33 and 34). The student's physics reasoning skills have notably improved. He is more comfortable with independently approaching problems now. He still needed help with qualitatively assigning ideas to formulas. For this, I am continuing to encourage a more qualitative understanding of the material first as opposed to immediately reaching toward formulas."
"We covered magnetism, the idea of ferromagnets (all spins aligned in same direction) and paramagnets (all spins in different directions, so net direction of spin is zero [can align in presence of magnetic field]). We also covered magnetic flux (the amount of magnetic field lines perpendicular to an area divided by the area). Also magnetic induction: moving a charge through a magnetic field creates a force. However, that force does not do work, work is done by the electric force (this come from work being force times displacement, and a magnetic field does not displace the charge, the electric field does). The student needed help with the concept of flux being defined by the direction of the magnetic field lines in relation to the area. Mathematically it is analogous to work done by a force, depending upon direction."
"Today's topics were conduction, what makes materials conduct or not, different types of conductors, how all of that is determined by electron energy levels, and a few other things. The student is having some trouble finding out what is on the final, so we are just reviewing things he found confusing."
