Wednes-Day 2
Chem 5 - reviewed Aufbau etc rules (took 25 minutes due to no work at home); finished Period 4 configs and orbital diagrams; explained Aufbau exceptions.
Started electron configs of transition metal cations.
Tomorrow - finish unit with anions and isoelectronic series.
Chem 7/8 - caught up to 5th, and got to explaining Aufbau exceptions.
finish unit with anions and isoelectronic series, tomorrow.
APB - finished pendulum SHM; fully explained when and how to use net force to center of circular arc = mv^2 / 2 ; and, for non-uniform circular motion, that there is an overall net force that is the vector sum of the tangential weight force and the sum of the center-aligned forces.
We then did the energy curves for pendulums, as well as the s, v, a derivative curves.
We tried to reason each of the slopes and curves: here's the real reason!!!: since A is amplitude yet is ironically a horizontal displacement, A varies with actual height, delta y, which is related to (1-cos theta) so A should vary as the -cos theta function, which is what you see!
