Introduction to Physics Part 2
Course Length: 1 Semester
Has Textbook: No
In Part 2 of this textbook-free course, students continue to explore physics through the study of gravity, projectile motion, and Kepler's Laws of Planetary Motion. Students will also study the nature of matter and atomic structure to learn how the laws of physics apply on an atomic level. The knowledge of forces gained in Part 1 will be applied to liquids and gases to discover how these states of matter behave. Students will then be introduced to thermodynamics, mechanical and electromagnetic waves, and the Doppler Effect. The course will finish with a look at electricity, magnetism, and optics, including a study of mirrors and lenses.

It is recommended that students successfully complete Introduction to Physics Part 1 before enrolling in this course.
