Here are the screenshots and captions from last week . . .
TIme Stamp: Nathan Chen does SIX QUADS in the 2018 olympics in his redemption skate. First time in history. Li = Lf
PhySP18SS5.2.1 From Sheet 5.2.3
PhySP18SS5.2.2 Also from Sheet 5.2.3
PhySP18SS5.2.3 DANGER!! but useful
PhySP18SS5.2.4 Sheet 5.3.2
PhySP18SS5.2.5 Sheet 5.3.3 One of the most tedious problems of the year.
PhySP18SS5.2.6 Sheet 5.3.5
PhySP18SS5.2.7 Sheet 5.3.5
PhySP18SS5.2.8 Sheet 5.3.5 The hard part was using the ratios to help you unpack the Final momentum suitcase.
PhySP18SS5.2.9 Sheet 5.3.6 Just head-to-tail
PhySP18SS5.2.10 The return of the Gold Standard!! Sheet 5.4.5
PhySP18SS5.2.11 Glance Ball! The most points earned were 14 bonus. We are working on GLANCE BALL SQUARED. GB^2 for the hipsters.
PhySP18SS5.2.12 GLANCE BALL from the past.
PhySP18SS5.2.13 A true genius.
PhySP18SS5.2.14 Newton’s version of what Hooke looked like. FAKE NEWS!
PhySP18SS5.2.15 This COULD be Hooke.
PhySP18SS5.2.16 Two hours Division time given for reading this book. Have the NHS Library order it.
PhySP18SS5.2.17 Hooke’s microscope.
PhySP18SS5.2.18 A fold out from Hooke’s best seller Micrographia. Fleas were a real problem (Black Plague and all) The second pandemic of bubonic plague was active in Europe from AD 1347, the beginning of the Black Death, until 1750.
PhySP18SS5.2.19 Another major problem was head lice. Here he finally settles the mystery of how those infernal bugs hang on to hair follicles.
PhySP18SS5.2.20 We did an impromptu lab/demo with a hanging spring and came up with this graph.
PhySP18SS5.2.21 This is NOT Hooke’s Law.
PhySP18SS5.2.22 This IS Hooke’s Law
PhySP18SS5.2.23 Hooke’s Anagram. He didn’t want Newton taking credit for his discovery of a property of these new found springs made of the new alloy of “steel”.
PhySP18SS5.2.24 Another interpretation of Hooke’s Law.
PhySP18SS5.2.25 I asked Mrs. Davis to weigh in on the controversy.
PhySP18SS5.2.26 How Hooke made the springs.
PhySP18SS5.2.27 Hooke’s Apparatus
PhySP18SS5.2.28 . . .
PhySP18SS5.2.29 . . .
PhySP18SS5.2.30 One of the most important graphs in Mechanics.
PhySP18SS5.2.31 The +, – areas of those right triangles are VERY important for AP Physics.
PhySP18SS5.2.32 Compression on the left and stretch on the right.
PhySP18SS5.2.33 Another version of Hooke’s Law. Showing the Spring Force (Fs). It is ALWAYS trying to restore equilibrium and get back to it’s happy place. Isn’t that we are all trying to do?
