Course Description

How do we describe the motion of objects around us, and the forces that act on them? How do cars stay on those steep turns at Talladega? Why do the planets have the orbits they do? Did you know that a shell casing hits the ground at the same time the bullet does? These sorts of questions and more are the domain of classical mechanics, which describes everything from projectiles to machinery to spacecraft, stars, and planets amazingly well. Classical mechanics also provides a basis for the study of most "modern" subjects in physics, including quantum mechanics, general relativity, astrophysics, and elementary particle physics to name a few.

In PH105, we aim first to provide you with the fundamental physics background to understand the world in motion around you, and then use that background to delve into momentum, energy, oscillations, thermal processes, fluid mechanics, and more. Compared to PH101, the mathematical sophistication will be much greater.

PH 105 is our first calculus-based introduction to physics, and is aimed at students who desire (or require) a detailed working physics background, particularly calculations and problem solving. Laboratory experiments will augment lecture- and discussion-based learning, and introduce students to key experimental techniques and analysis. The course will stress a conceptual and mathematical understanding of everyday phenomena in terms of their basic underlying physical principles. Broadly, the course material can be grouped into the following areas:

 
 

Student Learning Outcomes

 
 
  • Course goals and objectives
Upon completion of this course you should have a basic understanding of classical mechanics for both discrete and continuous systems and thermodynamics. A good understanding of this material forms the background necessary for enrollment in PH 106 or PH 126. Expected learning outcomes include but are not limited to the following:
 
  • General learning outcomes for 100- and 200-level physics courses:
  1. Scientific method:
    Students will understand the scientific method and critically evaluate scientific information.
  2. Effective teamwork:
    Students will develop skills in working together in team activities.

 

  • Course-specific learning outcomes:
  1. Conceptual understanding of Newton's laws:
    Students understand concepts that require knowledge of Newton's laws of motion, and use Newton's laws to formulate a solution to physical problems.
  2. Conceptual understanding of conservation laws:
    Students understand concepts that require knowledge of conservation laws, and use them to formulate a solution to physical problems.
  3. Analysis of circular motion and oscillations:
    Students will solve problems involving analysis of circular and oscillatory motion of objects.
  4. Knowledge of continuous systems:
    Students will understand how to extend physical principles for discrete systems to describe the physical behavior of continuous systems.
  5. Knowledge of thermodynamics:
    Students will solve problems which require knowledge of the three laws of thermodynamics.

Exams and Assignments

 

Exams

There will be three “hour” exams, each covering several thematically consistent chapters. Two of the “hour” exams will be administered during laboratory periods, and one will be administered during the final examination period.

For the hour exams, you are allowed only the following items:

Writing implement(s)
Calculator (no cell phones or PDAs)
One prepared 8.5 x
 11 inch formula sheet (front and back sides allowed)

The hour exams may have slightly different formats, but each one is worth an equal amount (viz. 20% of your total grade each). The exam dates will be listed on the course calendar during the first week of classes.

Homework

Several homework problems will be assigned each day, both from your textbook and from other sources, amounting to approximately 15-20 problems per week. These problems will be posted on the course web page. You will turn in each day's problem at the start of the following day's lecture. The lowest two homework problems each week will be dropped. You may collaborate on homework, and are encouraged to, but each student must turn in his or her own work.

Quizzes

Fairly frequently, short in-class quizzes will be given. They will focus on the topics covered in the previous lecture, including but not limited to the problems assigned for that lecture. Quizzes will generally occur during the laboratory sessions, but are not limited to them.

Labs

There will be approximately 9 laboratory experiments through the term. Laboratory experiments will be worked in groups of 2-4. You will choose one experiment per week to write a laboratory report on as a group, due the following Monday at the start of the lecture period. Templates for these lab reports and the grading structure will be provided, though for each experiment there will be specific questions to be answered contained in the laboratory procedure document. Example raw data from the experiment(s) you did not choose to include in your report (e.g., printed data plots) should be included as appendicies in your report as evidence that you completed those experiments.

 
 

Grading Policy

 

Each of component of your grade is described above, and their relative weights in determining your overall grade are shown below. The lowest homework problem each week will be dropped.

Policy on Missed Exams & Coursework

 

If you have a legitimate reason for missing a homework assignment or quiz, you will be given the option to make up the homework set at a later date, or receive a 'bye' on that particular assignment. The reason must be documented in writing, and whether it is acceptable or not will be judged on a case-by-case basis. If possible, inform the instructor as soon as possible before the assignment is due.

If you have a legitimate reason for missing a major exam, then you must inform the instructor as soon as possible before the exam occurs. If the reason is acceptable, either the exam will be dropped for you, and the final exam will count proportionately more, or you may make up the exam at a slightly earlier or later date. We reserve the right to administer a modified make-up exam slightly differing from the exam the rest of the class has taken. There is no makeup possible for missing the final exam.

Acceptable reasons must be documented, if possible in advance, and may include but are not limited to: prior athletic commitments, medical issues, off-campus academic commitments, prior commitments to on-campus academic events, band travel, standardized testing, graduate school interviews, and certain personal/family issues. Unacceptable reasons are fairly numerous. Among the least likely to be accepted are oversleeping, leaving early for academic breaks, and fan travel to ‘away’ athletic events. 

 

Attendance Policy

 

In-class exercises or quizzes will be given frequently at the end of the lecture period. The lowest 2 quiz scores will be dropped. While attendance is not strictly required for laboratory periods either, it is hard to imagine how you will complete lab reports otherwise.

It is expected that students will attend class having found some utility in it, rather than out of a sense of coercion or obligation. We will not waste your time while you are there.

Policy on Academic Misconduct

All students in attendance at the University of Alabama are expected to be honorable and to observe standards of conduct appropriate to a community of scholars. The University expects from its students a higher standard of conduct than the minimum required to avoid discipline. Academic misconduct includes all acts of dishonesty in any academically related matter and any knowing or intentional help or attempt to help, or conspiracy to help, another student.

The Academic Misconduct Disciplinary Policy will be followed in the event of academic misconduct.

Disability Statement

If you are registered with the Office of Disability Services, please make an appointment with me as soon as possible to discuss any course accommodations that may be necessary. If you have a disability, but have not contacted the Office of Disability Services, please call 348-4285 or visit 133-B Martha Parham Hall East to register for services. Students who may need course adaptations because of a disability are welcome to make an appointment to see me during office hours. Students with disabilities must be registered with the Office of Disability Services, 133-B Martha Parham Hall East, before receiving academic adjustments.

Severe Weather Protocol

In the case of a tornado warning (tornado has been sighted or detected by radar, sirens activated), all university activities are automatically suspended, including all classes and laboratories. If you are in a building, please move immediately to the lowest level and toward the center of the building away from windows (interior classrooms, offices, or corridors) and remain there until the tornado warning has expired. Classes in session when the tornado warning is issued can resume immediately after the warning has expired at the discretion of the instructor. Classes that have not yet begun will resume 30 minutes after the tornado warning has expired provided at least half of the class period remains.

UA is a residential campus with many students living on or near campus. In general classes will remain in session until the National Weather Service issues safety warnings for the city of Tuscaloosa. Clearly, some students and faculty commute from adjacent counties. These counties may experience weather related problems not encountered in Tuscaloosa. Individuals should follow the advice of the National Weather Service for that area taking the necessary precautions to ensure personal safety. Whenever the National Weather Service and the Emergency Management Agency issue a warning, people in the path of the storm (tornado or severe thunderstorm) should take immediate life saving actions.

When West Alabama is under a severe weather advisory, conditions can change rapidly. It is imperative to get to where you can receive information from the National Weather Service and to follow the instructions provided. Personal safety should dictate the actions that faculty, staff and students take. The Office of Public Relations will disseminate the latest information regarding conditions on campus in the following ways:

  • Weather advisory posted on the UA homepage
  • Weather advisory sent out through Connect-ED--faculty, staff and students (sign up at myBama)
  • Weather advisory broadcast over WVUA at 90.7 FM
  • Weather advisory broadcast over Alabama Public Radio (WUAL) at 91.5 FM
  • Weather advisories are broadcast via WUOA/WVUA-TV, which can be viewed across Central Alabama. Also, visit wvuatv.com for up-to-the-minute weather information. A mobile Web site is also available for your convenience.
