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:
“The hurt is not enough:
I long for weight and strength
To feel the earth as rough
To all my length.”
—Robert Frost (1874–1963)
“We come into the world laden with the weight of an infinite necessity.”
—Albert Camus (1913–1960)
“Europe has lived on its contradictions, flourished on its differences, and, constantly transcending itself thereby, has created a civilization on which the whole world depends even when rejecting it. This is why I do not believe in a Europe unified under the weight of an ideology or of a technocracy that overlooked these differences.”
—Albert Camus (1913–1960)
