3/25Physics update and homework due 4/1

Hi folks,

Today we took some time to do a lab based on the material we have been covering lately.  In the lab, we measured the gravitational potential energy of a falling object and we compared that to the work done by that object on another object to find the energy efficiency of the system.   This encouraged some careful data collection as well as allowing us to put some of our new formulas to use.

Two assignments for homework next week.

1.  Please answer the questions on the Energy Efficiency Lab Question and Answers .pdf.  

2.  Please do the enclosed Energy Problem Set with Answers .pdf

4/29 Physics update and homework due 5/6

Hi folks, Today we took a bit of a deeper look into light and began our unit on optics.  We will do more with optics next week. For homework this week…I've changed my mind.  :) Remember that extra credit assignment I was talking about in class, well let's make it homework with extra credit possibilities.   Here's the scoop.  Take a look at this article by Randal Monroe from his What If blog.    https://what-if.xkcd.com/3/   You'll see how he uses different physics concepts and applies them to real world things even though the situation is fictional.  (Unless somewhere out there Yoda really is hanging out on some swamp planet…it's possible.)   Now you do it.  Pick any book, movie, comic or video game and apply some of the things we've learned this year.  I've included one of my ex-students papers for example.  It's very good be sure to take a look. For homework, Apply at least 5 different physics concepts to the situation. ...

Caerus Summer Mini-Class in July

Image
Hi everyone, I hope everyone is having a great summer.  I've been enjoying catching up on some reading and doing some much needed house/yardwork. Most of you are may already aware of the following free class but I'd like to invite you all personally.  If anyone would like to hang out with us next Saturday afternoon and enjoy a really fun class, we'd love to see you.  Also, please bring a friend!  Do you know anyone who might be interested in taking a fantastic English, Math, History or Science class?  If so, bring them along (or forward them this email….or both)!   Last but not least, we'd really appreciate it if you would take the time to pass this down any group lists of Facebook groups you may be on.  Here's the link to the website.   http://www.caerusacademy.com/free-july-mini-class.html Thanks again everyone.  Hope to see you next week!
