Week of September 19

This week marks the interim of our first quarter – wow!

This Week in Physics
First of all, please sign up for Remind.com if you haven’t already. Second, please read the assignments for your class period.
If you are in 1st: On Monday we will take our quiz over both goal set 1 and goal set 2. In addition, by Monday please take notes on both Motion in One Dimension Podcast 5 – Introduction to Acceleration and Motion in One Dimension Podcast 6 – Acceleration Signs vs. Velocity Signs. We will briefly debrief these brief podcasts and will then toss some cars back on the tracks to analyze accelerated motion graphs. Next we will do assignments 2 & 3 together in class. On the day after we finish these assignments, we will take a quiz over goal set 3. For that day please also take notes on Motion in One Dimension Podcast 7 – Introduction to Kinematic Equations and Motion in One Dimension Podcast 8 – Kinematic Equations Sample Problem. When announced please also take notes on Motion in One Dimension Podcast 9 – Introduction to Free FallMotion in One Dimension Podcast 10 – Free Fall Sample Problems, and Motion in One Dimension Podcast 11 – Terminal Velocity. Expect a unit test by the end of next week.
If you are in 4th/5th: Your assignments are exactly the same as 1st period’s.
If you are in 8th/9th: For Monday please finish both assignment 1 and the work on goal set 2 from your goal pakcet. Then read the blog for 1st period (above) and follow it with a one-day shift so that your quiz is on Tuesday, and so on.
If you are in 11th: On Monday we will continue to work on assignment 1 and goal set 2 from our goal packet. If you do not finish in class, please finish both assignment 1 and the work on goal set 2 from your goal packet. In addition, due Tuesday, please take notes on both Motion in One Dimension Podcast 5 – Introduction to Acceleration and Motion in One Dimension Podcast 6 – Acceleration Signs vs. Velocity Signs. On Wednesday we will take a quiz over goal set 1 and goal set 2. Next we will do assignments 2 & 3 together in class. On the day after we finish these assignments, we will take a quiz over goal set 3. For that day please also take notes on Motion in One Dimension Podcast 7 – Introduction to Kinematic Equations and Motion in One Dimension Podcast 8 – Kinematic Equations Sample Problem. When announced please also take notes on Motion in One Dimension Podcast 9 – Introduction to Free FallMotion in One Dimension Podcast 10 – Free Fall Sample Problems, and Motion in One Dimension Podcast 11 – Terminal Velocity. Expect a unit test by the end of next week.

Cool Science of the Week
Astrophysicists trying to understand the nature and origin of the universe (from a scientific perspective) often search for gravitational waves, or distortions in the dimensions of space and time, as predicted by Einstein’s general theory of relativity. Recently scientists from the LIGO (an observatory run by Caltech and MIT in Pasadena) detected gravitational waves from a collision of two black holes that are 1.4 BILLION light years away. Nothing, including gravitational waves, travels faster than the speed of light (which Einstein also proved), so, in scientific terms, that means that the collision occurred 1.4 billion years ago, which also means that these black holes are now most likely one single supermassive black hole!
