Important Information for Physics 20700 students:
Course Objectives: Students are expected to understand the basic physics involved in mechanics (the study
of motion and its causes) and in thermodynamics (the study of heat and work) which is needed for
science and engineering. The emphasis will be on analytical reasoning and problem-solving skills.
A list of course objectives is given below.
Reading Assignment: The text material that will be covered in class each day is listed on the Class
schedule. You should read the indicated sections in the textbook before coming to class. Solutions of some
illustrative examples will be presented in lecture.
Homework: The homework problems are taken from the textbook. In addition, students will be
able to use WebAssign to practice solving homework problems online. WebAssign will evaluate
your homework. You will need the access card that comes with your textbook. If you have
purchased a used text, you will be able to purchase access to WebAssign online. To see detail of
the access to WebAssign, please go to
http://www.sci.ccny.cuny.edu/~vitkalov/teaching/teaching.html
Grades: Grade will be based on the highest score obtained in a) and b):
a)
exams (3 midterms + final)
80%
homework (WebAssign)
10%
lab reports (7)
10%
b)
exams (3 midterms + final)
lab reports (7)
90%
10%
Exams: There will be three midterm exams (120 min.) and a final exam (140 min.). No exam grades will be
dropped and no make-ups will be given except in the case of documented illness.
Labs: The Physics Department Lab manual is available on line at
http://www.ccny.cuny.edu/physics/upload/207.pdf
The Physics Department Lab schedule is available on line at
http://www.ccny.cuny.edu/physics/upload/Phys-207-lab-schd-fall-2015.pdf
There are seven labs to be completed during the semester; see the schedule on the next page. Lab reports
must be submitted at the beginning of the following lab period. Note that the grade of incomplete (INC) will
be assigned for Physics 20700 if all seven lab reports have not been submitted by the required dates.
Recitations: Please be aware that there has been a recent change in Physics 207. Instead of special sessions
for tutoring, as in the past, this semester each week there will be either a lab or a recitation. The lab TA will
be responsible EVERY week to teach the lab alternating with the recitation at the time and in the same room
that is scheduled for the lab. The recitation sections for Intro Physics 207 are mandatory for students to
attend. TAs are responsible for both lab and recitation for the assigned section: TAs will take attendance for
recitations just as they do for the labs.
Effort required: Don’t underestimate the amount of effort required for you to succeed in this course. Many
students, in particular those who have not taken a previous course in physics, will need to spend 5-10 hours
per week, every week, studying physics and doing the assigned homework problems, in addition to the time
spent in lecture and lab (7 hours per week).
Academic Integrity: Academic dishonesty is prohibited in the City University of New York and is
punishable by penalties, including failing grades, suspension, and expulsion.
Course objectives: After successfully completing this course, students should be able to
1. recognize and use SI units and be able to use vectors and their components.
2. understand the relationships between position, velocity, acceleration and time in the motion of
physical objects
3. understand the concepts of force and equilibrium and their relation to Newton’s laws of motion.
4. understand and apply the concepts of work and energy, including kinetic and potential energy;
understand and be able to use the principle of conservation of energy.
5. understand and apply the concepts of momentum and impulse; understand and be able to use the
principle of conservation of momentum.
6. understand how to describe the rotation of physical objects; understand the concept of torque as
applied to the equilibrium of objects.
7. understand gravitational interactions and their relationship to satellite motion.
8. understand the phenomenon of simple harmonic motion.
9. understand and apply the basic principles of fluid mechanics as applied to buoyancy and fluid flow.
10. understand the properties of temperature and heat.
11. understand and apply the first and second laws of thermodynamics involving work, heat and
internal energy.
