Our dynamics test is Monday.
- As you prepare for the upcoming
test, look again at all of the examples in chapter 5 and section 1 of chapter
6. Try solving them yourself before you look at the text’s solution.
Remember, that may be more than one mathematical representation for the same
physical situation (different coordinate system, etc.).
- There are some good problem solving
hints on page 124 for N2 problems & exercises.
- Especially practice free-body
diagrams and writing the various force components for N2. (Chapter 3 has more
examples on writing a vecor in terms of its components.)
Today we'll work through as many
exercises as possible. Most of these involve applications of Newton's Second
Law. Along the way we'll study circular motion.
