# What Is the Difference between Mass and Weight?

Weight and mass are two different properties. Mass is the measure of the amount of material in an object. Weight on the other hand is the gravitational force that is acting on a body mass. Note that mass does not change with a body's position, movement or modification of its shape unless a part of the material is added or removed.
Mass is a measurement of the amount of matter something contains. Weight is a measurement of the pull of gravity on an object.
With regards to Physics the difference between mass and weight is that mass refers to the measure of matter that an object contains while weight refers to the measure of how strongly the force of gravity pulls on matter.
Mass is best described as the amount of matter in an object, and it determines the force which can be exerted by an object. An objects mass remains the same regardless of location. Weight is the measure of gravitational pull on an object, which means that an object will be lighter or heavier in different levels of gravity.
Mass is the amount of matter that something is made of or the amount of matter an object contains. Weight is a measurement of how much the force of gravity acts on a mass of a given size or the force exerted on that object by gravity.
The difference between weight and mass is that mass is always a constant at any place and time while weight depends on gravity at the place. Mass is measured using balance while weight is measured using scale. The other difference is that mass can never be zero but weight can be.
Mass is a measurement of the quantity of matter in an object while weight is a measurement of force on an object due to gravitational pull. Mass is always constant because it is determined by the amount of matter contained in an object. Weight on the other hand depends on how much gravity is acting on an object.
