What is the definition of Physics?
Key concepts in physics include:-
Laws of Motion: Described by Isaac Newton, these laws govern the motion of objects and the forces acting upon them.
Gravity: The force of attraction between objects with mass, described by Newton's law of universal gravitation and expanded upon by Einstein's theory of general relativity.
Electromagnetism: Describes the interactions between electrically charged particles and magnetic fields, as encapsulated in Maxwell's equations.
Quantum Mechanics: A branch of physics that deals with the behaviour of particles at the atomic and subatomic scales, characterized by probabilistic outcomes and wave-particle duality.
Relativity: Albert Einstein's theories of special and general relativity, which revolutionized our understanding of space, time, and gravity, especially at high speeds or in strong gravitational fields.
Thermodynamics: Studies the relationships between heat, energy, and work, encompassing concepts such as entropy, temperature, and the laws of thermodynamics.
Optics: The study of light and its interactions with matter, including reflection, refraction, diffraction, and polarization.
Nuclear Physics: Explores the properties and behaviour of atomic nuclei, including nuclear reactions and the structure of matter at the subatomic level.
Physics not only seeks to understand natural phenomena but also has practical applications in technology, engineering, medicine, and other fields. It provides the foundation for many other scientific disciplines and plays a crucial role in shaping our understanding of the universe and our technological advancements.
