Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each othe

but the two words don't mean the same thing. The difference between mass and weight is that mass is the amount ofmatterin a material, while weight is a measure of how the force of gravity acts upon that mass.1
Since a body of mass M experiencing a force F accelerates at a rate F/M, a force of gravity proportional to M would be consistent with Galileo’s observation that all bodies accelerate under gravity toward Earth at the same rate, a fact that Newton also tested experimentally. In Newton’s...
Mass is defined as the amount of matter that an object contains, while weight is the force that a mass-containing body exerts on another body purely under the influence of gravity. In our vernacular, “mass” and “weight” are terms that are often seamlessly interchanged, but technically, ...

Mass is the amount of matter present in a body while weight is a measure of how strongly gravity pulls on that matter. Mass is an intrinsic property of the body and remains the same wherever the body might be. Weight is a force, and force is (Mass * Acceleration). The weight of an...
While on Earth, mass and weight will have the same value (if you happen to be standing in a location where the force of gravity is 1G). However, if you were to relocate to an area where there was a gravitational shift, your mass would stay the same while your weight would change. ...
