Physics and Chemistry

Physics & Chemistry underlie all natural and human created phenomena, although other kinds of information transfers, such as those facilitated by the genetic code or communicated between organisms, may also be critical to understanding their behavior. In this course, students will learn 4 Core Ideas-PS1: Matter and Its Interactions, PS2: Motion and Stability: Forces and Interactions, and PS3: Energy, and PS4: Waves and Their Applications in Technologies for Information Transfer.

Physics and chemistry may overlap when the system under study involves matter composed of electrons and nuclei made of protons and neutrons. On the other hand, chemistry is not usually concerned with other forms of matter such as quarks, mu and tau leptons and dark matter.

Although fundamental laws that govern the behaviour of matter apply to both in chemistry and physics, the disciplines of physics and chemistry are distinct in focus:

Physics is concerned with nature from a huge scale (the entire universe) down to a very small scale (subatomic particles). All physical phenomena that are measurable follow some behaviour that is in accordance with the most basic principles studied in physics.[1][2] Physics is involved with the fundamental principles of physical phenomena and the basic forces of nature, and also gives insight into the aspects of space and time. Physics also deals with the basic principles that explain matter as substance and energy, and may study aspects of atomic matter by following concepts derived from the most fundamental principles.

Chemistry focuses on how substances interact with each other and with energy (for example heat and light).[3][4] The study of change of chemical substances (chemical reactions) and synthesis lies at the heart of chemistry, and gives rise to concepts such as organic functional groups and rate laws for chemical reactions. Chemistry also studies the properties of matter at a larger scale (for example, astrochemistry) and the reactions of matter at a larger scale (for example, technical chemistry), but typically, explanations and predictions are related back to the underlying atomic structure, giving more emphasis on the methods for the identification of molecules and their mechanisms of transformation than any other science.

Physical chemistry and chemical physics underline the connections between physics and chemistry.
