ASU Fall 2016 Session A Week 5 Update

PHY 121 continues on. A better performance on Test 4 than on Test 3 so feeling like some of the missing pieces are falling into place. Not a perfect score, but a B+ on it. Still a bit shaky on some topics. Michel van Biezen’s videos on YouTube have been great. I spent a bit of time going through his videos earlier in the week. I need to do a little bit better job actively solving the examples he works. Definitely could use another week or so to digest all this information and work problems.

Week 5 finds me venturing into some new topics in PHY 121- Part II of our textbook moves from Newton’s Laws into Conservation Laws. I don’t remember much about these topics from my physics course at UCR almost 20 years ago so interested to learn more.

Week 5 topics include:

  • Momentum and impulse
  • Momentum conservation
  • Center of mass
  • Kinetic Energy and Work
  • Work by variable forces
  • Potential energy and mechanical energy

PHY 122’s fourth lab has us looking at Friction this week. This had a lot of really great information on coefficient of static and kinetic friction courses. In retrospect, I should have looked ahead a bit more at the labs. There was some good information in the lab manual that would have helped me out a week or so ago.
