Description: Physics 3. In this class, we will mostly focus on rotational mechanics starting with basic concepts and gradually ascending to more complex one such as torque, rotational mass, and angular momentum. At the end of the year, we will discuss oscillations and waves. The math prerequisites are basic geometry and trigonometry.
