What is weight?

Weight

In science and engineering, the weight of an object is the force on the object due to gravity. Its magnitude (a scalar quantity), often denoted by an italic letter W, is the product of the mass m of the object and the magnitude of the local gravitational acceleration g; thus: W = mg. When considered a vector, weight is often denoted by a bold letter W. The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, about one-sixth as much on the Moon, and zero when in deep space far away from all bodies imparting gravitational influence.

Famous quotes containing the word weight:

    But I saw the little-Ant men as they ran
    Carrying the world’s weight of the world’s filth
    And the filth in the heart of Man—
    Compressed till those lusts and greeds had a greater heat
    than that of the Sun.
    Dame Edith Sitwell (1887–1964)

    We come into the world laden with the weight of an infinite necessity.
    Albert Camus (1913–1960)

    Not the less does nature continue to fill the heart of youth with suggestions of his enthusiasm, and there are now men,—if indeed I can speak in the plural number,—more exactly, I will say, I have just been conversing with one man, to whom no weight of adverse experience will make it for a moment appear impossible, that thousands of human beings might exercise towards each other the grandest and simplest of sentiments, as well as a knot of friends, or a pair of lovers.
    Ralph Waldo Emerson (1803–1882)
