PHYSICS IN DAILY LIFE REVIEWER

Physics

the study of how matter and energy interact with each other

James Clerk Maxwell

developed the fundamentals of electromagnetism through a set of mathematical equations, which form the basis of electromagnetism

Heinrich Hertz

performed the experimental proof of Maxwell's equations

Classical physics & modern physics

two branches of physics

Mechanical, thermodynamics, acoustics, optics, electromagnetism

classical physics examples

Atomic physics, nuclear physics, quantum mechanics, and relativistic physics

modern physics examples

Classical physics

physics developed before the 20th century, describes the visible world

Modern physics

post-20th century physics, they primarily revolve around the study of particles that are smaller than the atomic size and are moving at the speed of light (reveals the invisible)

Mechanics

focuses on the study of the relationship and interaction of force and motion

Thermodynamics

focuses on the interaction of heat and temperature and how it is converted into work

Acoustics

deals with the study of mechanical waves in different media, and it encompasses production, control, transmission, reception, and efforts of mechanical waves

Optics

deals with the study of the nature and properties of light, its behaviors, and interactions

Electromagnetism

deals with the study of how electricity and magnetism are interrelated with each other

Atomic physics

focuses on the nature and properties of the atom with respect to its electron configuration

Nuclear physics

focuses on the interaction and activities in the nucleus of an atom

Quantum mechanics

deals with the interaction of matter and energy within the constructs of quantum physics such as the wave-particle duality

Relativistic physics

deals with the study of the universe's space, time, mass, and energy at very high speed (ex. the speed of light)
