Description This is the second course in a two-semester sequence in introductory, calculus-level physics. Physics is concerned with the description of how nature behaves. This behavior is described mathematically and verified by experimental measurements. In the first semester, you were introduced to Newton’s Laws of motion, Conservation's Laws, and applications. This semester will build upon the fundamental concepts that were learned in the first part of this sequence. This semester will begin with an analysis of waves. Waves are a concept that will prove useful for the study of both sound and light. Our discussion of light will include the optics of lenses and mirrors along with physical optics which includes the concepts of interference, diffraction, and polarization. The semester will end with a discussion of Thermodynamics.

Course requirements will include the following: A. Quizzes A quiz will be given Thursday of every week. It will be on the material covered in the previous week. Each quiz will be graded out of 10 points. The total points for Homework and Quizzes will account for 15% of the final grade of this course.

5
Course requirements will include the following: B. Homework Students should answer as many questions and work as many problems from the ends of the assigned chapters as possible. They will not be graded, but students may (and should) ask questions in class about solutions. Sample problems will be worked in class as chapters are completed, and other solutions will be posted on physics bulletin boards. Questions and problems similar to those at the ends of chapters are likely to be found on quizzes and the final exam. Occasionally, extra credit problems may be assigned.

6
Course requirements will include the following: C. Midterm Exams There are 3 midterm exams. (best 2 of 3) There are 3 midterm exams. (best 2 of 3) D. Final Examination The final examination will cover all aspects of the entire course. It counts 30% of the final grade.

7
Course requirements will include the following: E. Review Article/Presentation: You will be asked to write an review article on a topic related to what you learn in this course. This can be done towards the end of the semester. The score of this article would be 15% of the final grade of this course. You are required to give a presentation prepared on your article at the end of the semester. The presentation should be on Power Point. The date will be announced.

8
Grading Policy The graded aspects of the course are weighted: Midterms (best 2 of 3) 40% Final Exam 30% Lecture HW & Quizzes 15% Review Article/Presentation 15%

Oscillatory motion is a repetitive motion back and forth about an equilibrium position. Swinging motions and vibrations of all kinds are oscillatory motions. All oscillatory motion is periodic.

13
Our goal in this chapter is to study the physics of oscillations. Much of our analysis will be focused on the most basic form of oscillatory motion, simple harmonic motion. We will start with the kinematics of SHM. Then, we will examine oscillatory motion from the twin perspectives of energy and Newton’s laws. Finally, we will look at how oscillations are built up by driving forces and how they decay over time.

14
Before Lecture #1 Simple harmonic motion is closely related to circular motion. Much of our analysis of oscillating systems will be based on the law of conservation of energy. Please review: Uniform circular motion. Ch#7 Restoring forces and elastic potential energy. Ch #10 Energy diagrams. Ch #10 http://www.physics.uoguelph.ca/tutorials/shm/Q.shm.html
