Physics is about the fundamental natural laws governing our universe. Taken as a whole, physics can be considered as the behaviour of just two fundamental quantities (space-time and mass-energy) in the presence of just four fundamental forces (gravitational, electromagnetic and strong and weak nuclear forces). Using physics, a small set of profound natural laws thus can be used to make sense of the complexities of the natural world, as well as the design and operation of our technology. Physics can be divided into different fields of study, with "classical physics" covering mechanics, acoustics, thermodynamics, electromagnetism and optics, and "modern physics" encompassing relativity and the quantum mechanics of light of matter. This course is called Physics 2 as it examines the conceptual basis of electromagnetism, optics and modern physics and is a companion course to Physics 1, which covers mechanics, acoustics and thermodynamics. In this course students are provided with a comprehensive introduction to key concepts for physical science students, and obtain practice with relevant calculus based problem solving and experiments.
