PICS FROM LAST WEEK
-
- Slide 7.194 SpaceX finally did it!
-
- Slide 7.195 “Just read the instructions”
-
- Slide 7.196 . . .
-
- Slide 7.197 . . .
-
- Slide 7.198
-
- Slide 7.199 Hopefully, we will have no more of this left in the ocean.
-
- Slide 7.200 . . . this meme came out about 30 minutes after SpaceX was victorious.
-
- Slide 7.201 Mystery problem. This came from a problem I worked in 2013. It is problem number 9 on one of our worksheets. Not sure which one.
-
- Slide 7.202 Mr. Pentacost is doing n amazing job of teaching Impulse. Here are some of his slides.
-
- Slide 7.203
-
- Slide 7.204
-
- Slide 7.205
-
- Slide 7.206
-
- Slide 7.207
-
- Slide 7.208
-
- Slide 7.209
-
- Slide 7.210
-
- Slide 7.211
-
- Slide 7.212
-
- Slide 7.213
-
- Slide 7.225 Person on the left is in an inertial frame of reference; Person on right is in a non inertial frame of reference. Person on the right is fooled into thinking he is on earth.
-
- Slide 7.226
-
- Slide 7.214 Sound waves require enough air molecules that will compress and rarefact (spread out). We can pick out this compression and rarefaction on an ociloscope. No sound in a vacuum. In space no one can hear you scream. (Alien: 1979)
-
- Slide 7.215 The higher the frequency, the higher the pitch (soprano). The greater the amplitude, the higher the volume.
-
- Slide 7.216 The soundwaves that you hear throughout the day are a superposition of tens to hundreds of pure frequency waves.
-
- Slide 7.216 If we add the two top sound waves through superposition, they cancel each other and there is no sound. This is the tech behind noise cancelling headphones. They do a pretty good job of cancelling constant humms like a lawn mower or a jet airplane. Not too good at canceling something like . . . my voice. Too many frequencies and amplitudes to deal with in real time. Sorry boys and girls. Can not silence me yet!
-
- Slide 7.218 Sound waves are NOT electromagnetic waves. Sound waves are converted to EM waves at the microphone.
-
- Slide 7.219
-
- Slide 7.219b
-
- Slide 219c
-
- Slide 7.220
-
- Slide 7.221
-
- Slide 7.222: Please don’t let this be you in college. I’ve seen too many former students party up, then flame out in college.
-
- Slide 7.223
-
- Slide 7.224
-
- Slide 7.227. On the right, light bends towards an extremely massive object. On the right light bends because the reference frame is accelerating. Einstein used this thought experiment to illustrate his principal of Equivalence. (see slide 7.231)
-
- Slide 7.228
-
- Slide 7.229
-
- Slide 7.330
-
- Slide 7.331 KNOW THIS!
-
- Slide 7.332 Polaris is our North Star now, but since the Earth precesses (with an omega of 26,000 years) the North Star changes. Our next North Star will be Thubin (I think).
-
- Slide 7.333
-
- Slide 7.333b We precess like a top losing enough energy that it is ready to fall.
-
- Slide 7.333c
-
- Slide 7.334 Our biggest suitcase so far.

- Slide 7.339
-
- Slide 7.340
-
- Slide 7.341
-
- Slide 7.342
-
- Slide 7.343 Impulse is the area of the trapezoid with it’s build up section and fade out section. Notice that the plot of time averaged force vs. time is always a rectangle which starts when the function stars and ends when the function ends.
-
- Slide 7.344
-
- Slide 7.345
-
- Slide 7.346

-
- Slide 7.371
-
- Slide 7.376 I think this is the way they design semi’s in Sweden or Denmark or somewhere over there. Interesting manipulation of air.
-
- Slide 7.377 Check to see where your favorite big city is on this graph. If you learn to interpret these kind of graphs for fun, your Science Reasoning ACT score will naturally go up.
-
- Slide 7.378
-
- Slide 7.379 This is the second bit of evidence I have that animals are starting to work together. Humans days of dominance on this planet are numbered.
