Course Description:

Physics 221, a 4 credit-hour course, is the second of a three-semester calculus-based physics sequence.P220 and P221 are required for engineering and BS Chemistry majors at UTM.It also provides the necessary background for the engineering students intending to transfer as well as chemistry and mathematics majors.This course covers such fundamental topics as electric charge and field, electric potential, Gaussís law, capacitance and resistance, electric circuits (AC and DC), magnetic field, induction, a synopsis of Maxwellís equations, if time allows geometrical and physical optics.The labs are included.



Mathematics 251 and Physics 220are prerequisites for this course.You are expected to be fluent in algebra and trigonometry and have a working knowledge of such mathematical operations as differentiation and integration.See Appendix E and page A12 of the text.


Laboratory work Ėan integral part of this courseómay include the usage of such methodologies as significant figures, error analysis and propagation, graphs and slopes, and linear regression.The experiments are included in the course are listed on my web page.†† Laboratory reports will be collected and graded.Usually the lab reports will be due week after the day of the experiment.

Laboratory work is scheduled in rooms EPS 224.I will provide more information about the labs and their operation.


Homework problems will be assigned during the lecture, and will be graded.Due date for the homework will be announced in class.Late homework will not be accepted without a valid excuse.


Five tests are scheduled during the semester ( Jan. 26, Feb. 23, , March 30, April 27,

and Final examination on May 9,7:45-9:45 am) .The relative weighs for quizzes, laboratory and examinations and the scale for the course grade are provided below.

WEIGHTS: Quizzes 10%, Laboratory 10%, Homework 15%, Midterms 40%, Final 25%.

Grade Scale: 90-100=A, 80-89=B, 65-79=C, 50-64=D, < 50 =F

Elevator Policy:

In case there are physically disabled students in the class and both elevators fail to work in the EPS building, an alternate class meeting will be arranged only for the disabled students.You may call me at my office number or the department office at x7430 and leave a message.I will call you and arrange a special make-up session for you depending on the circumstances.
