Pre- or co-requisite: MATH 20100. (Required for all students in the Physical Sciences, Engineering and Computer Science.) 3 lect., 2 lab/workshop hrs., 4 cr. Materials fee:$10

Modality

This is an in person class. Attendance is expected at all lectures and labs.

Grading

• Labs: 20%
• 2 Midterms: 20% + 20% = 40%
• 1 Cumulative Final: 40%

Homework

Homework problems will be assigned nearly every week, but will not be counted towards your grade.

Instructions will be presented in class.

Labs

All the lab experiments and reports must be done to pass the course.

Academic Integrity

The university has a published policy on academic integrity that may be found at: https://www.cuny.edu/about/administration/offices/legal-affairs/policies-resources/academic-integrity-policy/ Ignorance of this policy is no excuse. A student who cheats or plagiarizes may incur academic and disciplinary penalties, including failing grades, suspensions, or expulsion.

Policies specific for this course and some clarifications regarding what constitutes unacceptable academic dishonesty: For homework, you may work with classmates but you will be required to submit your own homework. Posting HW questions verbatim (word for word) to online homework helping sites or forums (Chegg, Yahoo answers for example) in the hopes of having someone else provide you with a solution is considered academic dishonesty as it is plagiarism. This can and will lead to adverse actions including removal from the course and reporting the case to the college academic integrity office.

Attendance Policy

Students are expected to attend every class session of each course in which they are enrolled and to be on time. The professor has the right to drop the student from the course for excessive absences. For this course, two weeks of unexcused absences will constitute an excess of absences. When a student is dropped from the course due to excessive absences, the Registrar will enter the grade of WU.

Communication

To stay within the guidelines of FERPA, we will only reply to your official ccny or cuny mail. Please do not use your yahoo or gmail or other personal accounts to communicate regarding course activities. Also, be professional in your communications. Include your name, course number, and EMPLID if you expect administrative actions to be needed.

Disability Statement

In compliance with CCNY policy and equal access laws, appropriate academic accommodations are offered by the AccessAbility Center . Students who are registered with the AccessAbility office and are entitled to specific accommodations must arrange to have the Office notify the Professor in writing of their status at the beginning of the semester. If specific accommodations are required for a test, students must present the instructor with a form from the Accessibility Office at least one week prior to the test date in order to receive their accommodations.

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 use 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 use 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 and Kepler's laws.
8. understand the phenomenon of simple harmonic motion.
9. understand and use the basic principles of fluid mechanics as applied to buoyancy and fluid flow.
10. understand the properties of temperature and heat.
11. understand and use the first and second laws of thermodynamics involving work, heat and internal energy.
