Recent Tutoring Session Reviews
"I introduced him to his upcoming chapter on Light and Reflection by covering topics presented in the book. We discussed similarities and differences between flat and spherical mirrors and reviewed formulas relating object distance, image distance, focal length, and radius of curvature. We used spoons and images from the book to demonstrate behavior of light. He understood concepts and was able to discuss and predict behavior of light with various types of mirrors. Hopefully he will be prepared ahead of his class that will present the material this week."
"Reviewed worksheet on orbital movement. The student had missed the lecture over the topic so I focused on explaining the concepts and deriving the equations. He was much more proficient with the material by the end of the session."
"During this session we focused on reviewing for the student's upcoming test. The test was on electricity and magnetism. We started off looking at circuits set up in series and parallel and what is constant across both of them. We looked at forces from magnetic field and an electric field on a moving charged particle. We also looked at Kirchhoff's rules. We reviewed the two right hand rules and when and how to use them. We ended with looking at the force between two parallel wires carrying current."
"We reviewed Coulomb's law and electric field. We went over similar problems to his homework assignment. We spent most of the time on the superposition principle with electric force and field. We also looked at the acceleration of an electron between two parallel plates. He needed to be reminded of a few things when we started, but he was able to figure out most of the problems on his own. We got through all problems similar to homework, so next time we can focus on electric potential and circuits."
"Finished physics practice exam 1 with the student covering topics of KE, PE, momentum, rotational KE, and helping him conceptualize the problem, write down the appropriate equations, and solving. He has good math skills. I think with our sessions and him doing the following two practice exams he'll be ready for his midterm."
"In this session we discussed periodic motion, mostly of springs. This mostly involved Hooke's law, but also included potential energy of springs, and finding spring constants given the forces and displacements. The student was very comfortable with both of these calculations, and since he is allowed to keep equations handy on his tests and quizzes, he writes them at the top of the page as a reminder. He found these problems all very easy, even the problems at the end of the sets that are challenge problems."
"We went over kinetic and potential energy including work and how each concept ties together. We worked through several problems including concepts with frictional forces, force and distance, work, inclined planes and how to analyze and manipulate word problems."
"Covered moment of inertia formulae for spheres, hoops and solid cylinders. Worked problem of computing relative bottom of hill speeds using conservation of energy including potential and both types of kinetic: translational and rotational ... connected by the no-slip equation v=wr. Gave advice on common gotcha mistakes involving radius vs diameter, centimeter vs meter, and omission of units."
"The student is covering magnetism and induction in her class currently. We discussed the right hand rules, the Biot-Savart law, and then went through derivations of the Biot-Savart for loops and solenoids. We then discussed Ampere's law, and magnetic field inducing torque. The next topic of the class is Lenz's Law and Faraday's Law. I briefly touched on both of those, and we will go into further detail next session."
"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 together her teacher had given her. It was a multiple choice work sheet that focused on these topics. The student 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 with a few topics including the difference between electric potential and electric potential energy, as this is a common confusion. 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 did some textbook problems (maybe 6 problems) covering Work and Energy. I think 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."
