Study:
Lecture notes (my Ch. 1 and Ch. 3), Lecture slides, and
suggested book problems.
•
Including understanding the computer program that calculates the
motion of the massspring system.
•
Do I get a formula sheet?
No, because there are only a few:
•
Spring force, friction force, equation of motion, definition of
acceleration, definition of velocity, exact solutions for x, v, and a
using calculus (today), frequency of oscillation (today)
Today:
