c. Lagrange's equations

Detailed Description of Conduct of Course

The class format will be lecture/discussion. Part of the class time will be used for the development of the formal theory while the rest of the meeting time will be devoted to solving example problems. The majority of students’ time outside of the classroom will be spent in working on problems. Some of the assigned problems may be computer-based.

Goals and Objectives of the Course

The following student abilities are expected to be developed or enhanced due to this course:

1) Students will be able to apply Newton’s Laws to a broad range of physical systems.
2) Students will be able to solve problems involving both static and dynamic systems.
3) Students will develop proficiency in the basic mathematical methods used in everyday physics.

Assessment Measures

Student comprehension of the material will be based on instructor feedback on assigned homework problems, in-class discussions and students’ presentation of their solutions, and periodic exams.
