Yes, mass is often defined as the "amount of matter". This definition is rather informal, but it gives you the general idea. Mass is the property of matter that (a) produces inertia; if an object has more mass, it takes more force to accelerate it, and (b) that reacts with other masses, through the force of gravitation.
Mass is the amount of matter in an object and matter is anything that makes up any type of substance such as liquids, gases, and solids. Therefore they do not have the same definition.
Nothing. A mass represents the totall inertia of a certain object, which is dependant on the amount of matter and energy that constitutes such object. Gravity has nothing to do with mass. However, weight is dependant on gravity. weight is a force, force= mass x acceleration. When we talk about weight, the gravitational force affecting a certain object, we mean mass x gravitational acceleration (g) so weight = mass x g.
Mass does not mean density. Density is mass per unit of volume. If, the volume of an object is the unit volume then the measure of its mass and density will be the same.
Density means that a specific amount (a specific mass) of material occupies a specific volume of space, and this characteristic is constant for a material throughout the universe. We measure density as mass per unit of volume.
The mass of an object is the amount of matter that an object has. It is almost the same as weight, but weight is dependent on gravity, while mass is universal.
Mass is the amount of matter, if that is what you mean.
"Amount" is one of those rubber words that can mean different things to different people. The 'amount' of matter in an object could be the object's mass, or it could be the object's volume.
It is a measure of the amount of matter in an object.
Mass is actually a physical concept and is a measure of the amount of matter in an object.
The word mass in science means the density of an object.
Mass is the amount of matter in an object and matter is anything that makes up any type of substance such as liquids, gases, and solids. Therefore they do not have the same definition.
The statement is not scientifically accurate. A rolling stone, like any other object with mass, has mass. Mass is a measure of the amount of matter in an object, and it is always present regardless of whether the object is at rest or in motion.
the amount of matter in a substance
In maths matter normally refers to the mass of an object
mass: the amount of matter in a substance (your welcome)
Mass is essentially a measure of the amount of matter an object contains, but more specifically: It is a measure of an object's resistance to accelerate.Weight is a measure of the amount of force acting on an object, though it is typically associated with gravitational force.The formula, F = M * A (Force = Mass * Acceleration) relates all three quantities.An object contains a certain amount of matter, and the more matter it has, the more difficult it is to accelerate the object. This mass is typically measured in grams or kilograms, and it is found by finding the weight of on an object and dividing it by the acceleration (Usually that is gravitational acceleration).Note that Mass and Weight are NOT the same thing. Weight, in our perspective here on earth, is the acceleration of gravity (9.81 meters per second) times the amount of mass we contain. Therefore, a person with 10 kilograms of mass weighs 98.1 Newtons on earth. If that same person were to be on the moon, their mass would remain the same, as no matter has left them; however, their weight would be smaller because the acceleration of gravity is only 1.62 meters per second on the moon.As an object's mass increases, it's weight increases as well. However, as an object's weight increases, it does not necessarily mean that its mass is increasing as well, for the magnitude of gravity's acceleration may just be getting larger, but the object may not be gaining any more matter.In a nutshell: Weight is the measure of the force on an object depending on the mass of said object and the gravity which acts upon it. Mass is the resistance of an object to accelerate, depending on the amount of matter it contains.
I don't get the significance of the 'suitcase', but the mass of any object is constant, no matter where you take it.
