Textbook: The required text is Classical Mechanics by J.R. Taylor
 Corequisites: PHY 2048 or the equivalent. Fluency in algebra, trigonometry and calculus is necessary for your success in Mechanics I. A course in
differential equations is highly recommended. Calculus III will
be used extensively throughout the course.
Synopsis: This course is the first part of twosemester sequence (PHY 32214222) in undergraduate level classical mechanics. The goal of the first semester is to develop a bridge from the elementary course (PHY2048) to the Lagrange and Hamilton formulation of mechanics to be studied in depth in the second semester (PHY4222) of the course. Topics include matrices, vector calculus, Newtonian mechanics, frames of reference, conservation laws, harmonic oscillator, and calculus of variations.
Physics 3221 will cover selected
chapters of the textbook. See Calendar
for details. Lecture slides will be posted.
Words of Advice for success in this course
Grading policy:
Homework: There will be ten GRADED
homework assignments during the semester, due on the dates indicated
on the schedule.Homework assignments, subject to change are posted on the Homework link of this website. Make your solutions neat, concise, and intelligible.
Points may be deducted if it is difficult to find and/or understand
the solutions. Overdue homework will not be graded.
The graded homeworks will be worth 13% of the total grade.
Inclass exams : In addition to the
homework assignments, there will be FOUR INCLASS Exams of 50 minutes
duration, tentatively scheduled for September 13, October 4, October 25, and November 22. Each of these exams will be worth 19% of the total
grade. The lowest score of the four inclass exams will be dropped.
Hence the inclass exams will constitute 57% of the total grade.
Inclass quizzes: One quiz near the end of the semester
will be used the fulfil the academic
learning compact (ALC) requirement. The ALC quiz is compulsory and constitutes 3% of your total
grade.
Final exam: There will be a two hour,
cumulative final exam. Details about the exam format will be
posted here. Formula sheets for the final exam will be allowed.
The final exam will be worth 27% of the total grade. The final is
scheduled for Friday, December 13, 12:30 PM to 2:30 PM in NPB 1101.

Your grade will be posted on SAKAI. If you have not used Sakai, please visit Sakai Help and learn how to use it. Here is a guideline for your final letter grade: 85%100%, some
type of A; 65%84%, some type of B; 50%64%, some type of C; below
50, will be decided by the instructor. These thresholds may be lowered,
depending upon numerous factors, but will not be raised. The course
grades are not curved.

Holidays (no classes): Labor Day: Monday, September 2; Homecoming: Friday, November 8, Veteran's Day: Monday, November 11, Thanksgiving: WednesdayFriday, November 2729.
STUDENTS WITH DISABILITIES: Students who require
accommodation for disabilities must first contact the Dean of Students
Office. That office will provide documentation, which the student
must bring to his/her instructor during the first week of the semester.
ACADEMIC HONESTY: Each student is expected to
hold himself/herself to a high standard of academic honesty. Under
the UF academic honesty policy, unauthorized assistance or the use
of unauthorized resources is strictly forbidden on workforcredit.
Although discussions among the students are highly encouraged, you
are to work alone on all homework assignments unless specified otherwise.
Fabrication or falsification of excuses or related documentation
is also a violation of the UF academic honesty policy. Violations
of this policy will be dealt with severely. There will be no warnings
or exceptions.
