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.
In physics, a physical body or physical object (sometimes simply called a body or object) is a collection of masses, taken to be one. For example, a football can be considered an object but the ball also consists of many particles (pieces of matter ).
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.

In string theory and related theories (such as supergravity theories), a brane is a physical object that generalizes the notion of a zero-dimensional point particle, a one-dimensional string, or a two-dimensional membrane to higher-dimensional objects.
The physical properties of an object that are traditionally defined by classical mechanics are often called mechanical properties. Other broad categories, commonly cited, are electrical properties, optical properties, thermal properties, etc. Physical properties include: [ 2 ]

In physics, a rigid body, also known as a rigid object, [2] is a solid body in which deformation is zero or negligible. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.
