**PHYS 151**

** **

**Overview and Course Learning Objective **– This course
focuses on motion of objects and systems in our physical world. Students will
learn how to use the fundamental laws of physics to model physical systems that
involve linear motion, curved and rotational motion, energy and motion,
oscillatory motion, and the physical modeling of thermodynamic systems and
fluids.

This course and its associated laboratory section are
entirely online. For this lecture section, the online book required is
“Physics”, 10’th edition by Cutnell and Johnson. __The book, reading
assignments, chalkboard examples, homework problems, and exams are all accessed
online through “Wiley Plus”. All students in this course must create an
account for themselves in Wiley Plus to purchase the online book and access the
online course materials and assignments. __You may create your account by
visiting https://www.wileyplus.com, and
typing in University of Nevada Las Vegas in the search box to find the
course(s) PHYS 151/152. Register for the course and pay for the online book
and course at that time.

In addition to Wiley Plus online, short video lectures and examples for each module or chapter are required viewing. These videos may be accesses through your UNLV online portal for the course.

**Assignments**

All course assignments except for the assigned video files are
accessed through Wiley Plus__. Each student must create their own account in
Wiley Plus to purchase the book and access the assignments__. Go to:

https://www.wileyplus.com/

to register yourself for the course prior to the start of the semester. You may type in “University of Nevada Las Vegas” in the search box on the Wiley Plus login page, then find the courses PHYS 151/152 to begin the registration process.

Each module or chapter covered in this course will contain 5 assignments. The five assignments for each module will consist of (1) reading assignment, (2) chalkboard video assignment, (3) question assignment, and (4) problem assignment. (5) Each chapter will also have two short video files to watch. The book, reading assignments, chalkboard examples, homework problems, and exams are all accessed online through Wiley Plus.

Reading Assignments – The reading assignments for each chapter will consist of a list of sections in the online or printed textbook that are required for study in that particular chapter.

Chalkboard Video Assignments – These are worked example problems presented as short videos.

Question Assignments – These are homework questions that each student must complete online prior to the due date for each question assignment. These questions are graded. Students are given more than one attempt at arriving at the correct answer, however credit for each question is reduced by 25% after two attempts and zero credit is given after the third attempt.

Problem Assignments - These are homework problems that each student must complete inline prior to the due date for each problem assignment. Home “problems” are generally more difficult that homework “questions”. These problems are graded. Students are given more than one attempt at arriving at the correct answer, however credit for each question is reduced by 25% after two attempts and zero credit is given after the third attempt. After the second unsuccessful attempt at a solution, a “hint” may be given for a problem.

There are also video files to be viewed for each chapter. These videos will cover important topics or examples for the given chapter. These videos are not part of Wiley Plus, but may be accesses through your UNLV online portal for the course.

Your homework grade, consisting of graded questions and problems in each chapter will contribute 20% of your total, final grade for the course.

**Course Schedule**

All course modules or chapters are immediately available
upon your registration for the course at Wiley Plus. In general, each module
must be completed per week of the course__. The exact due dates for each
module or chapter are explicitly listed on the Wiley Plus website for the
course.__ You may, if you like, complete the course at a faster rate than
the listed due dates. If a module or chapter is not completed by the listed
due date, however, a penalty is incurred. The exact penalty is indicated on
the website.

**Exams**

There will be three exams given during this course. These exams will consist of two midterms and one final exam. Each exam (including the final) will cover material in approximately one-third of the course. This will generally consist of only the course material that has been covered since the previous exam. I note, however, that exam 2 and exam 3 (final exam) are always “comprehensive” in nature since material presented throughout this course always builds upon, and thus requires knowledge and study of all previous course material.

Exams will be taken online through Wiley Plus. On the day of an exam, you may login and take the exam anytime between the hours of 8 am and 5 pm. Once you begin the exam, though, the system will limit you to 90 minutes to complete the exam. You MUST complete as much of the exam as you can during this 90 min. time period, as no extra time is given.

Each exam will consist of 20 questions and problems. There are no multiple attempts, and no hints or partial credit given. Some of the exam problems will be more difficult than others. Do the best you can and complete as many problems as you can in the 90 minute allotted time period for the exam.

Exam Content – as mentioned above, each exam (including the final) will cover material in approximately one-third of the course. There is so much material in this course that 20 problem exams will not be able to test you on all subject areas that are covered in the course, though we will try to include problems on as much material as we can. Also, do not expect that exam problems will simply be exact duplicates or “clones” of homework questions and problems. Exam problems will require that you apply the concepts, principles, and knowledge gained in the reading and video assignments as well as the homework assignments to similar, but generally new applications.

**Grading**

Your final grade for the course will be calculated per the following weighting:

Homework – 20%

Exams – 60% (Three exams at 20% each)

Laboratory grade - 20% (Grade obtained in PHYS 151L).

Since the laboratory grade is part of the grade for this
course, you will be __given the same final grade__ in both PHYS151 and PHYS
151L.
