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.

Famous quotes containing the words physical and/or body:
“How many young hearts have revealed the fact that what they had been trained to imagine the highest earthly felicity was but the beginning of care, disappointment, and sorrow, and often led to the extremity of mental and physical suffering.”
—Catherine E. Beecher (1800–1878)
“It is remarkable that the dead lie everywhere under stones.... Why should the monument be so much more enduring than the fame which it is designed to perpetuate,—a stone to a bone? “Here lies,”M”Here lies”;Mwhy do they not sometimes write, There rises? Is it a monument to the body only that is intended?”
—Henry David Thoreau (1817–1862)
