"[COVERED]: We discussed some areas that the student requested.
1 - Starling's Forces: We began by reviewing osmolarity, and discussed how the Osmotic Pressure gradient influences the direction of motion of water; using salmon as an example, tying that into the homeostatic actions of the kidney and its endocrine control. Based on this, we defined tonicity. From there, we discussed how the movement of serum into and out of the capillary.
2 - Torque: We began with a discussion of rotational equilibrium and discussing the two ways that questions are asked about it: in rotational equilibrium, and in how that equilibrium changes to disequilibrium (angular acceleration). We briefly related the variables of linear kinematics to those of rotational equilibrium (which although not tested directly on the MCAT, is needed to explain the transition between equilibrium and disequilibrium; i.e., Newton's 2nd law for rotation). Part of this discussion was a cross-connection between uniform circular motion and periodic motion, in order to explain why we talk about angular velocity in SHM.
3 - Momentum: We discussed Newton's second law and how it applies only to forces outside of the system, even if that system is comprised of more than one particle. We discussed the corollaries in reference to momentum, energy, and work.
4 - We discussed terminal velocity.
5 - We reviewed how to determine the overall rate law of multistep reaction pathways.
[PROGRESS/CHALLENGES]: This was a great session for the student. She has applied herself and worked hard, and her ability to visualize these principles is really coming together. She finally understood osmotic pressure, and how tonicity was just defined relative to the cytoplasm, eschewing her prior "chart memorization" approach. By comparing the linear and rotational variables, she was able to finally understand a net Torque changing the angular velocity.
[EXTRA PRACTICE]: Further questions and reviewing the material to cross-connect as much as possible."
