Week of November 2, 2015

Happy November! Remember that we do not have school this Tuesday, November 3rd, as teachers will be going through district training.

This Week in AP Physics
We will continue our exploration of energy. Homework 1 is due on Monday. On Wednesday and Thursday we’ll finish our notes for the unit by covering the conservation of internal energy within a system and the concept of power. Homework 2 will most likely be due on Thursday or Friday. Ideally our unit 4 test will be next Monday, November 9, although there is a slim chance we will be ready for it this Friday, November 6. In addition, your lab report for the work-energy theorem experiment will be due on Tuesday, November 10. (Remember that the hardcopy will be due at the start of class on the due date; an upload  is due to TurnItIn.com by 3:00 of that day. Remember to write using Google Drive and share your document with me at alhsgb@gmail.com… Note that I do not use that for email correspondence.)

This Week in Physics
On Monday in class you will have a sub (your favorite sub!) You will take notes on the following podcasts IN CLASS (not as homework): Force Podcast 1 – Net External ForceForce Podcast 2 – Weight, and Force Podcast 3 – Normal Force. Be ready for a podcast quiz over those notes on Wednesday. We will expand on the notes from the podcasts and build toward assignment 1, which we should do by the end of the week. Most classes have a significant number of students who will be absent on Wednesday due to a field trip, so we’ll set our pace for the week as appropriate. Note: If you are in 1st period or 6th period, your lab report for the Human Cannonball Projectiles Lab is due on Friday, November 6. (Remember that the hardcopy will be due at the start of class on the due date; an upload  is due to TurnItIn.com by 3:00 of that day. Remember to write using Google Drive and share your document with me at alhsgb@gmail.com… Note that I do not use that for email correspondence. Be sure to use the lab document as well as the lab report writing guide and lab report rubric as you write.) Also note: If you are in 3rd period, we have yet to do this experiment. We will do it most likely on Thursday, and your report will be due next week.

Spooky Science of the Week
NASA’s Near-Earth Object Program continually monitors the universe for asteroids that may be on a crash course with Earth. They keep a list of asteroids with potential to collide with Earth and develop plans to save us just in case it happens one day. If you check the list, you’ll see that a collision is highly improbable anytime in the next couple of centuries. The problem with asteroids is that their trajectories often change due to gravitational interactions with moons and planets and collisions with other asteroids. Sometimes an asteroid suddenly appears without us having recognized its existence before. On October 10, NASA discovered Asteroid 2015 TB145, now nicknamed the Great Pumpkin Halloween Asteroid, which is due to fly just outside of our moon’s orbit on Halloween! This asteroid is about the size of a large skyscraper and would not make for a fun collision, but we are in absolutely no danger. Sadly, we also won’t be able to see it, since it’s passing by in the early afternoon, and it is going to be very dim even for those who are experiencing it during their nighttime. Like Linus’ Great Pumpkin, we could wait and wait, and we’ll never see it here in Avon Lake. Nonetheless, check out the news (or Twitter) on Halloween night, because professional and amateur astronomers who experience the asteroid in different parts of the world will sure to be posting cool images of it.
