- Physics is the science of energy and matter and how they relate to each other.
- An example of physics is the study of quantum mechanics.
- An example of physics is electrocution.
- Obsolete natural philosophy
- the science dealing with the properties, changes, interactions, etc. of matter and energy in which energy is considered to be continuous (), including electricity, heat, optics, mechanics, etc., and now also dealing with the atomic scale of nature in which energy is considered to be discrete (), including such branches as atomic, nuclear, and solid-state physics
- a specific system of physics
- a book or treatise on any of these
Origin of physicstranslated, translation of Classical Latin physica, physics ; from Classical Greek (ta) physika (lit., natural things), name given to the physical treatises of Aristotle: see physic
- (used with a sing. verb) The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics.
- (used with a pl. verb) Physical properties, interactions, processes, or laws: the physics of supersonic flight.
- (used with a sing. verb) Archaic The study of the natural or material world and phenomena; natural philosophy.
Origin of physicsFrom Latin physica, from Greek (ta) phusika, (the things) of nature, from neuter pl. of phusikos; see physic.
- The branch of science concerned with the study of properties and interactions of space, time, matter and energy.
- Newtonian physics was extended by Einstein to explain the effects of travelling near the speed of light; quantum physics extends it to account for the behaviour of atoms.
- Of or pertaining to the physical aspects of a phenomenon or a system, especially those studied in physics.
- The physics of car crashes would not let Tom Cruise walk away like that.
- plural form of physic
- third-person singular simple present indicative form of physic
From Ancient Greek φυσικός (phusikos, “natural”)
physics - Computer Definition
The science of matter and energy, and their properties and interactions in fields including mechanics, acoustics, optics, heat, electricity, magnetism, radiation, and atomic and nuclear science. Physics is the science of how things work.
The science of the behavior of the physical world. Stemming from the Greek "physis," which means the characteristics of nature, physics covers the structure of matter (atoms, particles, etc.) and a huge variety of subjects, including chemical bonding, gravity, space, time, electromagnetism, electromagnetic radiation, the theory of relativity, thermodynamics and quantum mechanics.
