Test Tomorrow

A rough week got worse with the death of a college friend. Test will be tomorrow. Make sure you touch base with me tonight if you have questions as I'll try to be on here from 8-10.

Practice Problems

1. A football player has a velocity of 3 m/s. If his mass is 48 kg, what is his kinetic energy.
   
2. Double the football player's mass. How does this affect his energy?
   
3. Now double his velocity. How does this affect his energy?
   
4. A girl sits a book with a mass of 1.2 kg on a shelf that is 1.4 m high. How much potential energy does the book now have?
   

Interesting Days Tomorrow and Friday

Tomorrow, Savannah Weaver, a senior from PCA, will speak to both 7th grade classes. Savannah is a certified VFR/IFR pilot and will speak about her journey to become a pilot as well as the physics and math needed as a pilot. We welcome her.

Friday will be our first lab of the year. We will be dropping a few interesting things from some rather high spots here at the school. I will have a short lab report to fill out Monday, and we will test Tuesday instead of this Friday as originally planned. I will post our PowerPoint in the next post to keep things clean and easy to find.

Test on Friday, Sept 17

Make sure you study your Energy notes. I will post the PowerPoint on Wed. Don't wait until then to study. Also, be sure to make up your missing work.

Test Next Wednesday, Sept 8

Seventh grade will test on Newton's Laws on Wednesday, Sept 8. I wanted to test on Tuesday, but since we will be off on Monday and it's going to be a long weekend, I think it's better to wait a day. A printed study guide will go home on Thursday. Please download the notes from this link. Simply enter the letters into the captcha box, click "download file" and then wait 45 sec. for the free download link to appear. Make sure to save the file. Books for studying are available for check-out if needed. Please let me know if there are any questions.
