Q: Why A: 'Shaking' and 'meddling' are the two basic means by which we can move our understanding *** Mechanical Energy : 
HRW: Chapter 15 ANNOUNCEMENT FOR TODAY (9/20/16): PLEASE (again) COME TO CLASS AT 3:30 pm (and prepare to stay until 5:50 pm). Note: We have not yet settled into steadystate. But this has become necessary for today. I beg your indulgence. 
If you are looking in this box to see (And if you are looking to the column at left for the assigned reading, you are also doing the right thing.) 0. Identifications: 1. Oscillations: 2. Gravitations:

F = kx 
HRW: Chapter 13 NOTE: These two chapters seem OUT of ORDER. This is intentional. 1) Simple Harmonic Oscillation and 2) Universal Gravitation For the moment, regard these as two separate and independent topicstwo pieces we need to begin this course. We will soon bring them together. 

September 26 
Bridge Topic (from Thingy to UnThingy) #1 > A Differential Equation. *** Space Time as Clocks 
After Tuesday's discussion, you might have a greater sense for which sections of the above chapters are being emphasized and which are not: GO BACK and REALLY READ the sections it seems that we are emphasizing. REALLY READ means (among other things): Pick at least two Sample (Solved) Problems and try to solve them without looking. 
NOTE: IF you feel at all behind with respect to these assignments, here's the 'TRIAGE' priority order: FIRST worry about anything related to Harmonic Motion; SECOND worry about Gravitation. (We might not get to gravitation next class.)
EXERCISES A. The Undercroft: Universal Gravitation Problems at end of Chapter 13: Problems 3, 19, 24, 31 The following "Problems" (not "Questions") at the end of Chapter 15. a) Problem 9. b) Problem 29. c) Problem 31.

A 2Dimennsional Arrangment of 
All Solutions must interweave Verbal Explanations and Pictures Through the StepByStep Series of Equations. Every LINE is a COMPLETE STATEMENT whether of English (i.e.: full sentence), Every question must be responded to with a thought process as described above and a final answer that is explicitly labeled as such (circled, boxed, bolded, etc.). For some of these HW's, you will have already seen answers in class. For some, you will not. The standards and expectations for thoroughness of communication are similarly high either way.


October 31  Capital Deltas, LowerCase d's & LowerCase Deltas; 


Derivation: Newton's Shell Theorem 
Chapter 21  Unthung 

November 7 
Derivation: 
PROOFS: 1. That The Oscillation of a SmallAngle Planar Pendulum is Simple Harmonic ("SHO of a Pendulum"). 2. That The Wave Equation Can Be Derived From an Application of Newton's Laws to a Long, Light String ("Wave Equation on a String") For both of the above, "Prove" means: Start with a fully labeled diagram. Then: Set up 2 columns and, by your own methods of rigorous, thorough, intuitively reasonable thought, create a full derivation for each of the requested proofs. Column 1 = Claims Research absolutely acceptable, but use such research to inform, not to replace, your thoughts. Cite any/all such research in a formal, proper manner, such as APA. Express all definitions and assumptions you find necessary and relevant to the task. Proceed claim by claim (complete thought by thought) from the givens you establish until you reach the desired conclusion. In general, the claim for each step will be expressed as complete thought of mathematics, i.e. an equation; the justification for each step will be expressed as a complete thought of English, i.e. a sentence. 

Distortion vs. Displacement 
Chapter 22 
3. ARGUE (rigorously and convincingly, but in English) that the common sense and/or the fundamental laws of classial mehanics would be violated if Fields did not exist. Again, just like (1) and (2), Start with a fully labeled diagram. Then: Set up 2 columns and, by your own methods of rigorous, thorough, intuitively reasonable thought, create a full derivation for each of the following requested proofs. Column 1 = Claims Research absolutely acceptable, but use such research to inform, not to replace, your thoughts. Cite any/all such research in a formal, proper manner, such as APA. This time, however, all claims might well be in English. This "proof" might well be a bit softer (more informal) than those for (1) and (2), but that might well make it more challenging.

(b) REVIEW/PRACTICE: 1 (general). Assuming the conservation of (electric potential) energy, the definition of electrical capacitance and Ohm's Law, TYPE out a full derivation for the current as a function of time in an RC Circuit. 2 (particular). Assuming the numerical values presented BELOW for a particular RC Circuit (two resistors in parallel, one in series both with the pair and with the capacitor), find the amount of time for the current to decay to half its original value. Emf = 9 Volts. C = 100 microFarads. R1 (in main loop of circuit, series with battery and capacitor) = 400 Ohms. R2 = 200 Ohms, R3 = 300 Ohms. R2 and R3 are both in parallel with each other. But that parallel configuration itself is in series with everything else.
