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).
The common conception of physical objects includes that they have extension in the physical world, although there do exist theories of quantum physics and cosmology which may challenge this.
