October 30

Periods 3-4, 8-9
As necessary, get a couple partners and go through the last quizzam. Solutions are in the Newton's Laws folder on our school site. Make any corrections and write down any questions that you may have on anything, so we can be sure to fix it up.

Then let's get back into circular motion. Watch and take notes on a video of examples of horizontal and vertical situations. There is a second one on the roller coaster loop the loop. With these, be sure to have our packet and you can try and finish before leaving:

Period 5
My apologies for being out today. We are going to start using one of the great human missions that is under development as a theme for much of the physics we will think about the rest of the year - human settlement of space, meaning sending people to the moon and to Mars. To get started, Newton's laws will play the single biggest role in understanding how this will work. Please watch and take good notes on a couple videos:
How rockets work (3rd law is key, action-reaction)
Sending humans to Mars - how will we do it  pick out what you consider to be the big challenges and key ideas to think about for such a mission. The panelists talk about numerous aspects of things to think about for this mission, which is likely the most ambitious project in human history! Incredible complexity to figure out and conquer!

Check out Video on NON-Gauss method

As we look to make things a bit more realistic, such as charged sticks from our past labs that actually have ends, we need to use a different approach than Gauss's law, which we can only use as an approximation for this like a stick. Check out this video (we'll call it NON-Gauss), which outlines what we'll get into tomorrow.

World's heaviest calibrated weight: 1,000,000 pounds (exactly!)

Check out this video, courtesy of Shantelle G., of the world's heaviest calibrated weight...it is exactly 1,000,000.0 pounds. Pretty crazy!!
