Physics (from the Greek, φυσικός (physikos), "natural", and φύσις (physis), "Nature") is the science of Nature in the broadest sense. Physicists study the behavior and properties of matter in a wide variety of contexts, ranging from the sub-microscopic particles from which all ordinary matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology).

The quantity of matter which a body contains, irrespective of its bulk or volume. It is one of four fundamental properties of matter. It is measured in grams in the SI system of measurement. Note Mass and weight are often used, in a general way, as interchangeable terms, since the weight of a body is proportional to its mass (under the same or equal gravitative forces), and the mass is usually ascertained from the weight. Yet the two ideas, mass and weight, are quite distinct. Mass is the quantity of matter in a body; weight is the comparative force with

The physics of the Stoics was, on the whole, identical with their theology, in which the formative power that makes each thing what it is and harmonizes all things was God. The key words in the Stoic vocabulary are all basically synonymous: God, Zeus, creative fire, ether, the word (logos), reason of the world, soul of the world, law of nature, providence, destiny, and order. The Stoics were monists. There is in their physics no qualitative difference between God and the rest of the universe; God is only the most tense (cohesive) creative aspect of the universe.
