Recent Tutoring Session Reviews
"During this session we covered torque. We discussed how to find torque and how it is an analogue to force in rotational motion. We reviewed what quantities had rotational analogues to linear quantities. We also covered center of mass and ways in which to find it. We discussed static equilibrium and how to use the knowledge that all forces equal zero and torque equals zero to set up equations to find the forces that are acting in a system."
"Student is continuing to work through the units on electricity. This week focuses on the pressure difference in a circuit and how it is necessary for light bulbs to light. She worked on worksheets that involved color coding parts of a circuit based on the pressure (potential) in that part of the circuit. She has been doing really well understanding the concepts of this unit. To confirm some of her hypotheses, we set up a circuit to test the brightness of bulbs in parallel."
"The student's class has begun studying magnetic fields, but not gotten too deep in this new topic yet. She suggested we focus on her homework from the previous unit which will be due this week - it is a large part of her class grade. We spent the session discussing the problems she was uncertain about and how to solve them... in particular, a circuit problem with emf sources in parallel and an RC circuit problem involving a transient current. We plan to tackle magnetic fields after spring break, in two weeks."
"The student and I covered Magnetism and went over homework problems related to this topic. The first set of homework problems were conceptual, multiple choice type questions, which she recalled mostly from class last week. The second homework set had problems to calculate magnetic force, field, etc. using basic equations. She seemed to recall her classroom lectures well. Lastly, we went over a final review of Electricity and circuits, as she is taking her make up test since she did not take the test last week. We reviewed electric charge, force between charges, current, resistance, and voltage as they relate to simple series and parallel circuits. We also reviewed how to calculate power using these properties. The student showed a grasp for circuits and how to find equivalent resistances, etc."
"Today we talked about the Divergence Theorem, and capacitance. The student was relatively comfortable with capacitance - it is something he's seen before, but now we're just working with slightly more complicated geometries. He had some trouble with the calculus behind the divergence theorem, although he did seem to understand the general concepts behind it. I outlined how to use the Divergence of a field in an integral to find the flux, and I showed him how to find the curl of a field using the determinant of a special matrix. These concepts seemed a little clearer to him at the end of the session, although he still needs to review 3D integrals and changing coordinate systems."
"In this session we covered transitions between displacement velocity and acceleration. The student is becoming more and more comfortable with the equations of linear motion and is able to dissect word problems better. We went over which terms are scalars and vectors. I have worked on grounding these definitions with real world examples so he can better recall which is which."
"The student has a physics final this Thursday. We reviewed basic electrostatics and magnetism, including the right hand rule, which all will help him in his upcoming final exam."
"The student and I covered both math and physics during this session. In math we went over using similar triangles to solve for unknowns which she really seemed to understand. In physics we went over how to properly write a lab report and went over a review sheet cover said topic. It was pretty straight forward for her and it seems like it is preparing her to start writing lab reports in her physics class."
"The student and I covered topic relating to Ohm's Law, the power law and other things with relation mainly to capacitors. I also introduced him to some other material that has to do with applications of this area of science to technology (airbags, projectors, etc.). Overall, with the website and other review, we had a good introduction to the topic."
"During this session, the physics quiz was reviewed first, and then seven pages of physics homework was completed on momentum. Algebra homework was then completed from a class-given packet on exponentials. Lastly, the upcoming English test was prepared for by going over what would be on the test from past homework."
"Today we worked on thermal expansion and conductivity in preparation for an exam. We did several practice problems and I left her with some extra things to review. The student sometimes has trouble knowing where to start on a problem but once started doesn't seem to have any trouble getting the right answer. We also discussed strategies for multi step problems."
"Today we prepared for the student's exam tomorrow. The problems from homework sets 3, 4, and 5 represented the material that would be covered. First, we reviewed some questions from homework 3. These questions represented fairly basic FBD type problems, covering concepts such as friction, angles, tension, and inclined planes. As we covered homework 5 last time, we felt better focusing next on homework 4, which he had some trouble on. This problem set expanded on concepts in homework 3, such as pulleys, mass systems, and static friction. He will continue to prepare for his exam tomorrow."
