Recent Tutoring Session Reviews
"The student's physics class has moved on from learning how to use free body diagrams to implementing Newton's second law, F = ma, for a variety of dynamic physical systems. We worked together on an online problem set due Thursday, which had many conceptual questions involving accelerating systems with more than one object in play. We spent a particularly long amount of time discussing a challengingly worded problem involving an elevator and standing on a scale in the elevator, and I showed him exactly how to use free body diagrams to understand the balance of forces in an accelerating, gravitationally influenced system. Basically, the acceleration is in the direction of the net force, and whatever that net force comes out to be according to Newton's second law allows us to decide how to calculate the forces in play."
"The student and I covered changes in ideal gases. We used the ideal gas law. We also covered transfer of heat, work, and internal energy. We used pressure and volume graphs to find work."
"This session we covered ionic, covalent, and metallic bonding. I introduced the student to Lewis dot diagrams and used those to help explain covalent bonding."
