Meaning of Weight
What is Weight:
Weight, as such, designates the measure resulting from the action exerted by earth's gravity on a body. Weight can also be understood as a magnitude of said force. Likewise, by extension, it refers to any gravitational force that, in the Universe, a celestial body exerts on a mass. It comes from the Latin pensum.
Weight is also often referred to as the scale or apparatus used to weigh. Similarly, objects used to balance the measurement or to exert pressure on another object to be balanced can be designated as weight.
Weight can also be used in the sense of a burden or responsibility: "He was appointed minister and has shown that he is unable to bear the weight of his role."
Weight is also used to refer to an issue that causes grief or concern: "You have to deal with the weight of your decision."
As weight, the importance or influence of something or someone is also often called: "The mayor has always had a lot of weight in his party."
Weight in Physics
Weight is called the measure resulting from the action that, on the mass of a body, exerts the force of gravity of the Earth. Its unit of measurement is the Newton.
On the other hand, according to Physics, specific weight is understood to be the weight of a body or substance in relation to its volume or, in other words, its weight per unit of volume. Its unit of measurement is the Newton over cubic meter (m3).
