A physical body as a whole is assumed to have such quantitative properties as mass, momentum, electric charge, other conserved quantities, and possibly other quantities. An object with known composition and described in an adequate physical theory is an example of physical system.
A branch of physics that employs mathematical models and abstractions of physical objects and systems in order to rationalize, explain, and predict natural phenomena, as opposed to experimental physics, which relies on data generated by experimental observations. theory of everything (ToE) theory of relativity thermal conduction thermal equilibrium
Corpuscle (/ ˈ k ɔːr p ə s əl /) or corpuscule, meaning a "small body", is often used as a synonym for particle.It may also refer to: Corpuscularianism, the atomistic view that all physical objects are composed of corpuscles, which was dominant among 17th century European thinkers
A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as a value, which is the algebraic multiplication of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit. A physical ...
Matter is commonly defined as the substance of which physical objects are composed. It constitutes the observable universe. The visible components of the universe are now believed to compose only 4.9 percent of the total mass. The remainder is believed to consist of 26.8 percent cold dark matter and 68.3 percent dark energy. [99]

This category is for articles about specific, individual, mostly man-made objects (including matching sets). Buildings and bodies of water are not categorized here, nor are other geological, geographic or astronomical features. Classes of objects will be found under their respective collective names.
A material is a substance or mixture of substances that constitutes an object.Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function.
