PhyFl18SS3.3.1 Taken right before the In House Preseason Tournament. There are at least a few future millionaires in this picture.

PhyFl18SS3.3.2 1st Semester Hall of Famers. Chosen by proven brilliance of mind.

PhyFl18SS3.3.27 Wednesday’s bullet points

PhyFl18SS3.3.28 THursday’s bullet points

PhyFl18SS3.3.29 Prob 3.3 Back: Component Method and stack and rack

PhyFl18SS3.3.30 This is our class data from dropping the basketball from a the ceiling in the room (considered a small height) Small heights are any height where the time of fall is less than 1 second. The MAJOR problem with this time data is that it reduces down to 1 sig fig after you take into account the human reaction time (±0.15sec). One sig fig data is the death sentence in science. NOBODY will believe you.

PhyFl18SS3.3.36 Momentum is “moving inertia” We will study it in detail 2nd semester. Its the reason an object will keep on rising (but slowing down) after the upward force is removed. The object wants to keep going and going until the earth’s gravitational field gently calls it back home.

PhyFl18SS3.3.37 Prob 3.7.7

PhyFl18SS3.3.38 Prob 3.9.1 Vector PUZZLES!

PhyFl18SS3.3.39 We just mentioned the idea of MULTIPLYING vectors. Thats a second semester thing. Two ways to multiply vectors: Dot Products and Cross Products

PhyFl18SS3.3.40 Dot products are the source of all energy from forces. Cross Products are the source of all rotations and twists

PhyFl18SS3.3.41 . . . .

PhyFl18SS3.3.42 . . . .

PhyFl18SS3.3.43 These people take recorders to heights I have never heard before.

PhyFl18SS3.3.44 The Stella crowd was large on Saturday morning. Perhaps I should open my own coffee shop when I retire. What would I call it?
