Weight in a scientific language, and engineering, to force it can be said that the effect of gravity to mass to enter. But nowadays all people and even in many text official and legal, in place of the word weight, they use the order mass of the object.

the word weight, gravitational force entered from the land side to the objects and units that Newton is. The nature of the weight of the tube, the force and . The weight of an object to its mass of the object and the amount of the force of gravity entered on it, the object is dependent on. Weight, unlike Mass much a flat no, and if the force of gravity entered on the object changed, such as situations where the object to another planet, and transported, the weight of that object also change.

a large force, with W (for average) display. A large force is the mass of the object or m multiply in a great acceleration of the local gravity of the Earth, or g, then we can say: W = mg. In the Vector Space, weight, with the symbol W (for bold) display do offer. weight measurements in a standard system of international or SI Newton is considered. To sample the physical, with a mass of 1 kg, a weight equal to 9. the 8 Newton, in the surface of the Earth and on the lunar surface of equal weight, with about one-sixth (1/6) your weight on Earth and in space, away from the mass of precipitation in such a way that the effect of the force of gravity on the object is near zero it. can be said that the object almost weight.
