Two-dimensional motions include projectiles with air friction and motion under an inverse-square law central force. Motion of a system of particles includes the rocket problem, the two-body problem, coupled harmonic oscillators, and rigid-body rotation. Coriolis and centrifugal forces on the rotating Earth are studied. Finally, a thorough introduction of Lagrangian dynamics is presented. Prerequisite: PHYS 221 and MATH 241. One unit.

**Physics 344 - Thermal Physics**

*Fall*

How does a refrigerator work, and what is its maximum efficiency? How much energy do we need to add to a kettle of water to change it to steam? How and why does a snowflake form and how and why do liquids turn into solids? Why does an iron magnet lose its magnetism above a certain temperature? In fact, what do we mean by temperature, heat, and energy? Our understanding of these topics formed in two distinctly different ways starting about two-hundred years ago. James Joule, Sadi Carnot, and others developed what we now call classical thermodynamics, which treats matter and energy in terms of macroscopic quantities that obey the four “laws of thermodynamics.” Later, Ludwig Boltzmann, James Clark Maxwell, Josiah Willard Gibbs, and others applied classical mechanics and probability theory to molecules in an approach now called statistical mechanics and kinetic theory. In our modern approach to thermal physics, we add our understanding of quantum physics and use both classical and statistical approaches as best suits the question under investigation. Prerequisite: PHYS 221 and MATH 241. One unit.

**Physics 351 - Electromagnetic Theory**

*Spring*

The aim of this course is to introduce the basic principles of electricity and magnetism and their application in a variety of situations.
