Mass And Weight

[Emory]

What is the difference between mass and weight?

[Clynt]

Mass is the quantity of matter contained in a material and it remains same everywhere. Weight is the amount of force by which the mass is pulled by the gravitational force of earth and it can be increased and decreased by the impact of gravitational force  

[darrell]

Mass is constant but weight is a force exerted by that mass, that is dependent on the gravitational field and centrifugal force.  One Kg of mass weights less when on the moon or in orbit than on earth. It will weigh less at the equator that the North pole 

[Daman]

W=M=F/G Where: Weight = attracction between two massive bodies in a gravitational field.M= mass in 0-GF=acceleration constant.G= attraction one massive body to another(always a vectorial sum). Let us propose that an object weighs 1 Kg in 1-G.  We have a mutual attraction between the earth and the object, however the force will change as we move to or away from the earth. If we drop the object, it retains its mass but has become virtually weightless.If we acceerate the object upwards, the mass remains constant but the weight increases proportionally.  If we accelerate the object upwards at the same rate as it would fall, then we have twice the weight. Simplistic, I will admit, but it is correct.
