MATTER

Matter is generally considered to be anything that has mass and volume . The volume is determined by the space in three dimensions that it occupies. The mass is determined by its rest mass , which is measured by the acceleration a body has when a force is applied. The greater the mass, the slower the acceleration for the same force. Matter is thus a general term for the substance of which all observable physical consist.Typically, matter includes atoms and other particle that have mass, but this definition confuses mass and matter, which are not the same. Different fields use the term in different and sometimes incompatible ways; there is no single agreed scientific meaning of the word "matter," even though the term "mass" is better-defined. All object we see with the naked eye are composed of molecules, and molecules consist of atoms, atomic matter, made up of interacting sub atomic molecules, usually a nucleus of protons and of neutrons, and a cloud of orbiting electrons.
