Co requisite PHY211General Physics I Laboratory (to be taken concurrently with PHY210)

Course Material

1. Text (required): Physics for Scientists and Engineers, A strategic Approach Volume 1, by Randall D. Knight, Pearson Addison-Wesley Publishing, 2004.

2. Student Workbook to accompany the text (included with the text)

3. Syllabus (Provided)

Evaluation

Final grade computation: A: 87.5%, B+: 82.5%, B: 77.5%, C+: 72.5%, C: 67.5%, D: 57.5%.

1. Homework (10%)

Homework consists of (a) Text Exercises and Problems and (b) Student Workbook problems. Homework will be collected and graded. Homework is due one week after completion of the respective chapter lecture.

Home work is “acceptable” and full credit is given if more that 90% of the problems have been completed or attempted. If attempted, some initial work must be shown. The homework is considered “late” if the above conditions are not met. You may turn in two (2) late home works for full credit. After two late home works, homework will not be accepted. Homework solutions are on reserve in the Technology and Engineering Center (TEC) Library.

2. Reading Quizzes (5%)

At the beginning of most lectures your instructor will give a short reading quiz over the assigned reading material. These quizzes will not be returned.

3. Tests (85%)

Four tests will be given. Tests must be taken at the scheduled time and location (Mt. Laurel Test Center or during class). Tests are typically placed in the test center for a one-week period. The last test (#4) will be in-class during final exam week and must be taken on the date given on the “Official College Final Exam Schedule”. To be excused from a test (except the last test) you must phone or email the instructor before the end of the one week test period. Your instructor’s preferred method of contact is by phone or email. (Circle one or both)

Only one missed or excused test may be taken. You will be given the opportunity to make up this test during an assigned make-period during the final examination week. 10% will be deducted from this test if it is not excused (refer to requirement above).

4. Attendance

Students are expected to attend all class and laboratory sessions for the full duration of each instruction session. (Please refer to P. 17 “Student Attendance Policy” in the BCC Catalog for types of excused absences without penalty.) If you have an excused absence you may turn in homework, take a reading quiz or make up a laboratory within one week. To be excused you must contact the instructor before the class and/or the material is due. A student who is absent (excused or unexcused) more than four times is at risk of failing the course.

Class Participation · Assist or tutor others in or out of class · Contribute to “active-learning” class activities · Be an active lab-group participant · Be respectful, courteous and tolerant

Phy210 Chapter 1 Concepts of Motion

Objectives:

1. Develop a successful “way to study” physics

2. Draw and interpret motion diagrams

3. Describe motion with vectors

4. Use the concepts of position, velocity, and acceleration

6. Analyze and interpret motion problems

One way to study physics: (Suggested by Randall Knight, the author of our text)

· Read each chapter before it is discussed in class

· Participate actively in class

· After class, go back for a careful rereading of the chapter

· Finally, apply what you have learned to the homework problems at the end of each chapter

Special Note: Solutions to text homework are in the TEC library in the reserve section

Learning Activities:

1. Please begin your journey in General Physics I by reading the “Preface to the Student” by Randall Knight, the author of our text found on p. XV

Suggestion / Given Card Requirements: As you read examples and work problems form a list of the important concepts and equations. Use this list to form your given card (an instructor- provided blank “3 x 5” card, upon which you may write whatever information you like.) It will be collected with your test.

2. Solutions to text homework are in the TEC library in the reserve section

Please note: The Dynamics Worksheets are at the back of the student workbook. Use these for the Text Exercises and Problems with the icon.

Hints:

17. The figure shows the velocity-versus time graph for a moving object whose initial position is x₀ =20m. Find the object’s position graphically using the geometry of the graph, at the following times. (a) t = 3s (b) t = 5s (c) t = 7s

Hints: In drawing your position-versus-time graph start with x = 20m at t = 0. At 3s the position is 20m plus the area accumulated from 0s to 3s. Basically, you add more area as time increases. However, after t = 6s the additional area is negative.
