What is matter?

Matter

Matter is generally considered to be a substance (often a particle) that has rest mass and (usually) also volume. The volume is determined by the three-dimensional space it occupies, while the mass is defined by the usual ways that mass is measured (see the article on mass). Matter is also a general term for the substance of which all observable physical objects consist.

Famous quotes containing the word matter:

    In America the cohesion was a matter of choice and will. But in Europe it was organic.
