Course Description:
|
(1)
Classical Mechanics is one branch of physics. Also one of the
oldest areas of study. However, it is still an important area of physics
which also include the exciting research field of Nonlinear Dynamics and
Chaos.
(2)
When people think about a very hard problem, they use the word
“Rocket Science”. In fact, classical mechanics is “Rocket Science” which is
part of what we will learn in the course. However, I am not going to teach
anything new other than the LaGrange method. (A new technique to solve
problems without the use of Newton's laws) Then you may ask what I am going
to do as the instructor. We will combine several basic ideas you have learned
so far in physics courses to get close to the actual real-life situations.
Physics uses approximations to make life easier for solving problems.
However, to what extent we need to simplify depends on the accuracy needed.
For Example, you have worked with an object thrown up or down under gravity
and studied the details of motion assuming no air friction. You have also
studied friction (probably a constant frictional force) separately. In this
class, we will study the same problem with variable (with time, speed) and
position) frictional force and can add a rotational motion too. In general,
this makes the problem much harder, so you need to practice in order to
perform better with the technique.
(3)
Nature managed to stimulate the early human thought process to
invent controlled fires (probably observing lightning starting fires), the
wheel (observing boulders coming down), etc. Similarly, the
early humans start thinking about what they saw and tried to
understand why and how that happens. Central force motion and Orbits are a
great example of that, if you cannot think of the Newton Apple. We will
start this course providing you a historical approach to understanding
nature and starting with dimensional analysis and units, vector algebra,
familiar Newton’s laws (starting in 1-d and extending to 3D) and projectile
motion. We will then cover oscillations,
conservation laws, many body systems, and motion in central fields, motion
in electromagnetic fields, rotation of rigid bodies, Lagrangian
equations, Hamilton’s principle, and virtual work. By the end of the
course, you should be able to combine the different parts of physics you
learnt before and solve a problem close to the real-life situation. In other
words, without a good background in classical mechanics, it will be hard to
understand the new developments in Science.

If you are a 7600 you will have an additional requirement
beyond the 4600 students, please contact me for details.

Course delivery:
|
Course
will be delivered as an in-person class. (However, due to the prevailing
situation GSU could change the course delivery method to online (i- college) or mixed
delivery.) You will receive email notices on any announcements. The course content in i-college will have
several modules. After the Welcome Module, they will be labelled from
Module 1, 2, 3,….. Each module will cover one or
several chapters and will have submodules. The chapters and details covered
in each module, the schedule, goals and learning outcomes are listed under
each module.
|
|
Positive Study Habits:
|
·
Students who earn A’s and
B’s, follow both oral and written instructions in the
syllabus, go through the lecture materials multiple times to make sure
they can apply the concepts and techniques discussed in the lectures
to additional cases.
·
They would have worked out all
the assigned quizzes by themselves. They may have discussed with others and
carefully analyze the steps for solving a problem, but not copy material
and submit as their own.
·
Also, they refer to multiple Classical-Mechanics
books available in the library and additional material provided via i-college.

Assessments: |
·
(1) Homework: (i-college
Assessments and under the tab Assignments), also available in my GSU
Physics faculty website under teaching and courses
(http://www.physics.gsu.edu/perera/courses/cm4600/Spring2022/homework.html):~10%.
(2) Quizzes:~20% (3) midterm:~30% (4) Final
Exam: ~40%. (~ indicates
possible minor deviations.) Assignments will need to be uploaded as a
single PDF file. Please follow the
pattern given below for naming the file name. {Identifier} indicating, it
is homework (as set1, set 2, etc.). Your file name should be: (Example:Perera_U_classical_set1.pdf}

Grading Policy:
|
·
Four testing parts will contribute to the final grade. (1)
i-college Assignments (Homework) (2) quizzes in the- icollege (3 lowest will be dropped) and the (3) Mid
Term and (4) Final Exams. Expected learning outcomes listed above will be
tested in quizzes, assignments and in the Exams. Being able to solve the
problems similar to the assignments and problems discuss in class (but may
not be the same) should allow you to score well in the Exams. Quizzes could
be mostly multiple choice type questions. However, the problems in the exams
will be selected based on the limited time available to answer the
questions. The solution to the problems (From Asssignments
to Mid term and Final) should include steps
leading to the final answer. Majority of the points will be assigned to the
important steps. Even with a wrong final answer one can get most of the points
if the steps leading to the answer are correct. A basic (non- programmable)
scientific calculator can be used. The exams will be closed book closed
notes exam. An equation sheet will be provided. (Exams will be in class
unless GSU changed it to online under a lockdown browser due to the
prevailing situation.)
·
Very first Assignment will be testing
your knowledge on the syllabus and Roll
Verification. Four of the technical assignments will be
discarded giving the students the chance to obtain up to the full points
for submitting 10 of the assignments. Assignments may be graded randomly.
The solution to the problems should include steps leading to the final
answer. Points will be assigned to the important steps. All timely
submitted homework (Assignments) will be counted. Solution passwords will
be provided (iCollege or via in class) after the
submission of the answers. Link to Assignments:
·
http://www.physics.gsu.edu/perera/courses/phys4600/collection.html
·
(Passwords for the solutions will be provided after the due
date.)
·
Mid Term Exam will cover at least First 3 chapters: Feb
22 or 24
·
The Final Exam (cumulative)
will be a two and a half hour in
class test (could change to online)
will be on Apr 26th
– From 10.45 - 13.15

Roll Verification:
Withdraw:
Schedule: Disabilities: |
First Assignment in i-college will be used
for Roll Verification purposes and information gathering.
The last day students may withdraw with
either a "W" (Only for students performing at passing level) or a
"WF" grade is March 1st, 2022. Withdraw before that
deadline to avoid getting a "WF" while performing at passing
level. This is automatic and the instructor or the department cannot change
the grade.

general plan for the course delivery, deviations may necessary.
The Americans with Disabilities
Act (ADA) is a federal anti-discrimination statute that provides
comprehensive civil rights protection for persons with disabilities. Among
other things, this legislation requires that all students with disabilities
be guaranteed a learning environment that provides for reasonable
accommodation of their disabilities. Students who wish to request
accommodation for a disability may do so via the Access and Accommodations
Center (AACE) at https://access.gsu.edu/. Students may only be accommodated upon issuance of a
signed Accommodation Plan by the AACE Center (see: https://access.gsu.edu/testing-services/)
and are responsible for providing a copy of that
plan to instructors of all classes in which accommodations are sought.

Academic Honesty: Privacy: |
In addition to the standard person to
person exchange, sharing information/cheating (on to be graded assignments
such as quizzes, exams) via group messaging apps such as GROUPME or Slack
is a violation of the Academic Honesty Policy.
Academic dishonesty is a serious violation of the trust upon which
the success of our University depends. Cheating and plagiarism can not only
result in a poor grade and penalties from the University, but it can cause
your mentors and peers to mistrust you and could keep you from developing
the habits to make you a successful student and a successful worker in your
future career.
Violations of the academic honesty policy that end up in your
records appear on background checks if an employer contacts the university.
The University’s policy on academic honesty is published in the Student
Handbook,
https://deanofstudents.gsu.edu/files/2019/07/Academic-Honesty
Policy.pdf, and includes dishonest actions such as
cheating, plagiarism and facilitating academic dishonesty. Please be aware
that violations of this policy will result in a grade of “F” for the
assignment or the course. If you have any questions about the policy or are
unsure if something, you’re about to do counts as academic dishonesty,
please send me an email asking for a time to discuss the issue.
The instructor may be using Turnitin, Grammarly available through I-College to detect
plagiarism. You can use Turnitin to view the originality
score, which helps you to better understand plagiarism. In keeping with USG and
university policy, this course website will make every effort to maintain
the privacy and accuracy of your personal information. Specifically, unless
otherwise noted, it will not actively share personal information gathered
from the site with anyone except university employees whose
responsibilities require access to said records. However, some information
collected from the site may be subject to the Georgia Open Records Act.
This means that while we do not actively share information, in some cases
we may be compelled by law to release information gathered from the site.
Also, the site will be managed in compliance with the Family Educational
Rights and Privacy Act (FERPA), which prohibits the release of education
records without student permission. For more details on FERPA, go here
|
Sexual Harassment: |
In instances of
sexual misconduct, the present instructor(s) and teaching assistants are
designated as Responsible Employees who are required to share with
administrative officials all reports of sexual misconduct for university
review. If you wish to disclose an incident of sexual misconduct
confidentially, there are options on campus for you do so. For more
information on this policy, please refer to the Sexual Misconduct Policy
which is included in the Georgia State University Code of Conduct (http://codeofconduct.gsu.edu/).
