Catalog course description:
A continuation of Physics 10. Physics 11 is divided between classical and modern topics, including electricity and magnetism, circuits, special relativity, quantum aspects of nature, atomic and nuclear structure, and elementary particles.
Course Themes and Emphases:
• the microscopic structure of matter
• fundamental forces and new forms of energy
• extension of human "experience" to small spatial scales (quantum physics) and high velocities (relativity)
Physics, Principles with Applications, 5th Edition, by Douglas C. Giancoli, Prentice Hall (Upper Saddle River, New Jersey, 1998).
Final grades will be based on the following weighted components:
1) Final Exam 25 %
2) Hour Exams (2 X 12.5%) = 25 %
3) Laboratory 25 %
4) Homework 10 %
5) Quizzes 15 %
There will be two midterm exams and one final, comprehensive exam. Each exam will be closed book. Required formulae will be provided on the exam, but you will need to be able to recognize the meaning of the symbols in each formula and how to use them to solve problems such as those encountered in homework and lecture examples. Exam problems will be a mixture of quantitative problems like those encountered in homework sets and conceptual problems (multiple choice and short answer) like those encountered on weekly quizzes
A list of laboratory topics for each week is given below. Mr. Fontana will provide details on the operation of the laboratory portion of the course, including grading policies for labs.
Week 1: Electric Field Mapping
Week 2: Electric Circuits I (DC Circuits)
Week 3: Charged Particle Motion in a Magnetic Field (e/m)
Week 4: Electric Circuits II (AC Circuits)
Week 5: Measurement of the Speed of Light (c)
Week 6: Special Relativity Simulation
Week 7: The Photoelectric Effect (h/e)
Week 8: The Bohr Model and the Hydrogen Spectrum
Week 9: Nuclear Physics I
Week 10: Nuclear Physics II
Every Wednesday, homework sets will be collected for grading. No late submissions will be accepted. Homework assignments will focus on quantitative problems. You are strongly urged to work additional problems on your own, beyond those that are required.
Every Friday (except on Midterm exam days, winter break and the last class of the term) there will be a short (10 minute) quiz. Weekly quizzes will focus on conceptual problems, will generally be multiple choice, short answer and/or true-false questions that test your understanding of the concepts covered in the lectures and reading assignments for that week.
Help sessions will be every Tues. and Thurs. evening (beginning on Thursday, January 6) 8-10pm in Youngchild 90. A student assistant will run most of these sessions.
