Recent Tutoring Session Reviews
"Tonight the student did an amazing job with unbalanced forces. She is doing work that many college kids struggle with. I worked through several examples with her tonight. The examples utilized all of the information that she has covered to date. She very comfortable drew force diagrams and identified the forces acting on the systems. She then used the information and Newton's second law to find the acceleration of the system. We also used the statement "Friction is FUN" to solve for the coefficient of kinetic friction. F = Force of Friction U = coefficient of friction N = Normal Force. Finally tonight, we wrote some general rules for solving systems containing more than one object (masses on a pulley and ramp, Atwood machines). The number one rule we gave was to take the direction of motion of the system to be positive! Excellent work tonight and good luck on your test."
"Today we covered more circuits. We used the idea of current flow to distinguish between parallel resistors and series resistors. Similar to last session, we used mostly Ohm's law and formulas for power. We learned to redraw the circuits in combination circuits. Then we combined resistors using the formula for both resistors that are parallel and also in series. Student was eager to learn the material and teacher assigned enough practice. We reviewed that voltages in series resistors are added together to calculate total voltage while parallel resistors have the same voltage. Student has improved on learning the concepts behind circuits, especially solving total resistance of combination circuits."
"Since the student's next topics included sound and waves, I provided an upper level view of what he should expect during the next few days in class by going over basic wavelength, frequency, velocity, and period calculations and examples. We also went over a few definitions and concepts such as standing waves, resonating frequencies, transverse waves, and longitudinal waves. Next session he plans to have plenty of problems to go over from his lectures."
