PICS FROM LAST WEEK:
Will add captions later this weekend.
-
- PhyFl16P1SS68 — 4 big circular motion equations
-
- PhyFl16P1SS69 –when you walk at an angle between two dimensions, you each dimension gets a portion of your walk. Here the x axis got most of the portion of the walk because the angle was 30° above the x. Therefore, he is going to spend more time in the x than it does in the y.
-
- PhyFl16P1SS70 — This is the map view that came out of what we did on the west line.
-
- PhyFl16P1SS71 — KNOW THIS DERIVATION FOR THE TEST!
-
- PhyFl16P1SS72 — Here is another derivation.
-
- PhyFl16P1SS73 — A very important equation
-
- PhyFl16P1SS74 —
-
- PhyFl16P1SS75 –How fast does a LP albumn turn in radians per second.
-
- PhyFl16P1SS76 — 1.7.5
-
- PhyFl16P1SS77 –1.7.6
-
- PhyFl16P1SS78 — This was an election we had in my 9th grade advisory. Hmmmm….
-
- PhyFl16P1SS79 — 1.7.7
-
- PhyFl16P1SS80 –We discussed a little bit about Neutron Stars
-
- PhyFl16P1SS81 — Neutron Stars has the EM waves coming out of two spots on either side of the star. This makes it like a lighthouse in the universe.
-
- PhyFl16P1SS83 — Jocelynn Bell in the mid 60’s. She was about to discocver a whole new type of star.
-
- PhyFl16P1SS82 — me trying to give you an idea of the difference between white noise and the signal that Jocelynn Bell began to receive. The signals were further apart than what this screenshot shows (see next screenshot).
-
- PhyFl16P1SS84 — Here is the true signal.
-
- PhyFl16P1SS85 — Joy Division made this image famous. I always liked this image, but didn’t realize what it meant until a few years ago. WKellyann Conway is Trumps campaign managerhen I talk to people who are wearing this shirt
-
- PhyFl16P1SS86 — some people REALLY like the image.
-
- PhyFl16P1SS87 — This is a artists rendition of a Neutron Star. notice the EM waves are limited to two zones as the Neutron star spins.
-
- PhyFl16P1SS88 — more info.
-
- PhyFl16P1SS89 — Neutron stars are more massive than our sun, but they have collapsed after the star has exploded in a supernova and are not very large . . . therefore, they are extremely dense (one teaspoonful would weigh a billion tons).
-
- PhyFl16P1SS90 — what makes up a Neutron Star.
-
- PhyFl16P1SS91 — more details
-
- PhyFl16P1SS92 — You should memorize this just because . . .
-
- PhyFl16P1SS93 — my 5 displacements on my trippin runs on the west lawn.
-
- PhyFl16P1SS94 — The blue displacement is the overall displacement (∆x(tot))
-
- PhyFl16P1SS95 — We will learn to add these arrows. Weird, huh?
-
- PhyFl16P1SS96 — The data graphed from the Trippen Run
-
- PhyFl16P1SS97 — Here is an example of a duet. The graph below is always the slope of the graph above.
-
- PhyFl16P1SS98 — We will get into this a lot more in Packet 2
-
- PhyFl16P1SS99 — Secant BAD, YOU FOUND IT!!–> https://vimeo.com/29988162 in Tangent GOOD! The slope of the secant is the average velocity (v bar), the tangent slope represents the instantaneous velocity of the object.
-
- PhyFl16P1SS100 — Newton was the first one to see that this idea of average vs. instantaneous was a problem so what did he do about it? You guessed it. He invented Calculus.
-
- PhyFl16P1SS101 — Algebra BAD. Calculus GOOD!
-
- PhyFl16P1SS102 — We discussed the idea of significant figures a little bit. This will come up more in Packet 2 and 3, but for now, just make sure you have preferably three digits in your answers.
-
- PhyFl16P1SS103 — Fractions are bad unless they are coefficients. Coefficients come from mathematical relationships and therefore don’t have units (or the units divided out). Constants are numbers in Physics that DO have units. They are measured quantities. SOme are even UNIVERSAL CONTANTS (like the speed of light or the Universal Gravitation constant or Plank’s constant. These are true anywhere in the universe you travel.
-
- PhyFl16P1SS104 — So the Earth’s radius is 6.37 x 10^6 m. That is the radius to three sig figs. If you write out the number like 6,370,000 m, those zeros are not significant. They are merely placeholders.
-
- PhyFl16P1SS105 — This is an example of adding up three grades. The 80 is a test grade so it gets added three times. This is a weighted average that some teachers do. It is the same when we add up velocities of the trippin run. We did not spend as much time on each velocity so they are “weighted” differently.
-
- PhyFl16P1SS106 — If this was x vs.t then these velocities (slopes) COULD be added up as a simple mean because I spent the exact same amount of time going each velocity.
-
- PhyFl16P1SS107 — In this case, the two red lines red lines represent an objects two velocities, but notice that you spent A HECK OF A LOT MORE TIME going one velocity than the other so when you add them up the average velocity is “weighted” towards the positive velocity. SOmetimes we say this is skewed away from the middle of the two velocities.
-
- PhyFl16P1SS108 — another example
-
- PhyFl16P1SS109 — simple vs. weighted
-
- PhyFl16P1SS110 — As you go to the graph below you are taking the slope (or “derivative”) of the graph above.
-
- PhyFl16P1SS111 —
-
- PhyFl16P1SS112 — These are from the help session Wednesday lunch for the THQ1B
-
- PhyFl16P1SS113 —
-
- PhyFl16P1SS114 —
-
- PhyFl16P1SS115 —
-
- PhyFl16P1SS117 — Check this out. Look at how the students in 6th hour are helping other students before the THQ1B was handed in. ASSUMING that it is not just wholesale copying (which I don’t think it was), this is a very good thing.
-
- PhyFl16P1SS118 —
-
- PhyFl16P1SS119 —
-
- PhyFl16P1SS120 — Oh, Trifecta . . .
