what is the meaning of mass?

Answer 1

Measurement for an amount of matter subject to an inertia or resist ace to motion.

Answer 2

Not qualified to answer the theological question, but the physics / science answer is a bit easier for me.

'Measurement for an amount of matter' is concise and good as far as it goes, but you might say the same of volume and length.

Physical stuff is made up of atoms generally speaking, and atoms are reckoned to be made of up of smaller bits and pieces. All this stuff only has weight when there is gravity, like here on Earth. But it always has mass.

The more mass a bit of stuff has, the harder you have to push it to get it moving. Even in weightless space you have to push 10Kg harder than 1Kg if you want both to fly off at the same speed.

A canal boat full of coal is very massive (loads of Kilograms), but I can still pull it along the canal, it just takes longer to get it moving than a smaller less massive boat.

If you want to experience the difference between mass and weight get a very large person to collide with you and then try the same thing with a small cat or a three year old, unless they land on top of you, it is their mass and not their weight that you 'bump'.

Hope that's some help. If you're still stuck on the religious bit, try asking a (catholic) priest.

Answer 3

Mass is quantitative measure of inertia, or the resistance of a body to a change in motion. The greater the mass, the smaller is the change produced by an applied force. Unlike weight, the mass of an object remains constant regardless of its location. Thus, as a satellite moves away from the gravitational pull of the Earth, its weight decreases but its mass remains the same. In ordinary, classical chemical reactions, mass can be neither created nor destroyed. The sum of the masses of the reactants is always equal to the sum of the masses of the products. For example, the mass of wood and oxygen that disappears in combustion is equal to the mass of water vapour, carbon dioxide, smoke, and ash that appears. However, Albert Einstein's special theory of relativity shows that mass and energy are equivalent, so mass can be converted into energy and vice versa. Mass is converted into energy in nuclear fusion and

Answer 4

Weight is mass X Gravity

Mass is the density of an object and remains same anywhere.

Whereas weight changes according to the gravitational pull .
For example In moon you will weigh one sixth of what you are in earth as earth's gravity is 6 times greater than that of earth. But there will not be any change in your mass.
Weight is a force but mass is just a number.

Answer 5

Mass is the property of a physical object that quantifies the amount of matter and energy it is equivalent to. Mass is a central concept of classical mechanics and related subjects, and there are several forms of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.

In classical mechanics, there are three types of mass or properties called mass:

Inertial mass is a measure of an object's resistance to changing its state of motion when a force is applied. An object with small inertial mass changes its motion more readily, and an object with large inertial mass does so less readily.
Passive gravitational mass is a measure of the strength of an object's interaction with the gravitational field. Within the same gravitational field, an object with a smaller passive gravitational mass experiences a smaller force than an object with a larger passive gravitational mass. (This force is called the weight of the object. In informal usage, the word "weight" is often used synonymously(confused with) with "mass", because the strength of the gravitational field is roughly constant everywhere on the surface of the Earth. In physics, the two terms are distinct: an object will have a larger weight if it is placed in a stronger gravitational field, but its passive gravitational mass remains unchanged.)
Active gravitational mass is a measure of the strength of the gravitational field due to a particular object. For example, the gravitational field that one experiences on the Moon is weaker than that of the Earth because the Moon has less active gravitational mass.
Although inertial mass, passive gravitational mass and active gravitational mass are conceptually distinct, no experiment has ever unambiguously demonstrated any difference between them. Einstein developed his general theory of relativity by working on the assumption that this correspondence between inertial and gravitational masses is not accidental: that no experiment will ever detect a difference between them (the weak version of the equivalence principle) because "acceleration" (due to an external force) and "weight" (due to a gravitational field) are themselves identical.
