PH-100 Classical Mechanics
In this module we will explore the basic concepts of classical dynamics, namely force, energy, momentum, and angular momentum are introduced and applied in a variety of physically important situations such as particle collisions and planetary motion. The module will then introduce the principles of oscillations and introductory concepts of waves.
