Mon-Day 1
Physics - we looked at the equations that relate the various variables of motion: speed, distance, time, and acceleration.
We then applied these formulas, using specific test-taking skills of LABELLING the variables DIRECTLY in the question. We then look up the equation that contains ALL of the variables. We then plug in the data, and solve for the ONE unknown variable.
That is how we solve ALL of these one-step problems.
We then did a graphical analysis of motion. We saw how to get the distance travelled by an object by calculating the AREA UNDER THE LINE (ALL THE WAY down to the x axis) in the SPEED vs. TIME graph. To do so, we use the area of rectangle = bh and area of right triangle = bh/2 formulas.
AP Chem - did TWO gravimetric analysis problems, one in which we used the MOLE method, and the other in which we used the gram/mass method.
We also looked at and reviewed the combustion analysis setup.
