Mass doesn't change where ever the object or thing is but weight changes depending on where it is(depends on acceleration due to gravity-g)
Eg: Mass of object doesn't change either it is on moon or earth but weight changes(on moon it is 1/6 of that on earth).
You use different units for weight and mass because the weight of an object is dependent on the force of gravity and this means that weight can vary depending on where the object is. Mass on the other hand is constant regardless of force of gravity. For example, astronauts are weightless when orbiting the earth but their mass is exactly the same in space as it is on earth.
i think the reason is because people don't really use this any more and kids at younger age understand more clearly what they are trying to say to them
Density = (mass) divided by (volume). You must have known that at some level; otherwise, how did you decide that mass and volume were the things to measure, instead of, say, weight and temperature ?
The percentage of each isotope is different.
If you meant to say mass instead of weight, the acceleration of an object is inversely proportional to mass, because F=ma. However for falling objects where acceleration is equal to gravity, the weight is not a variable.
The weight is dependent on the mass. Mass is the same everywhere but since weight is mass * acceleration due to gravity, weight is the dependent variable.
It was a France scientist named Antoine Laurent Lavoisier.
Weight is not a physical property of an object, it is an effect, which varies from place to place. A given object will have the same mass no matter whether it is on the Earth, or on Mars, or somewhere in between.
The mass of an object does not change , but its weight can vary.
Mass is how much space an object takes up. While weight is just how heavy it is.
Mass instead of weight is used to measure the material that matter contains b/c mass is constant at all positions but weight changes with position.
Kilometers-distance.you are thinking of kilograms.kilograms- mass.Thats like me saying how many yards in a pound.And weight is messured in newtons you are thinking of mass eventhough everybody says weight instead of mass.Newtons-weight.All you have to do is divide 105/2.2
No. Mass is the weight of an object on earth. Scientists use mass instead of weight so the measurements will be the same everywhere. For example A big ballon has a relatively lower mass than a small sized stone
In the metric system (really called SI) weight is measured in units of newtons (lower case n to emphasize we are not talking about the scientist) and mass is in units of kilograms. W = mg (g =9.8) so weight in newtons equals mass in kilograms times 9.8.
The mass is a measure of the amount of matter present in an object whereas weight is a measure of the force on the object due to gravity. Weight is measured in Newtons, mass is measured in kilograms (pounds in the Imperial system) When we use the term weight outside of science we actually are referring to mass. mass is a measure of 'stuff,' of material that makes up an object. weight is the gravities affect on mass as you can see from the equation Fg=mg, m=mass g=gravity (on earth it is 9.8) and fg is weight in newtons
Weight = Mass *Accelerationdue to Gravityw = mg, where g~=9.81 m/s^2If you, instead meant to ask for density (d):d = mass / volumed = m / v
The word weight in every day speech means how much do you weigh converted back to mass. That is if I ask "what do you weigh?" but I want the answer in pounds or kilograms.In science mass is measured in kilograms (or pounds outside the science lab) but weight has more to do with the gravitational pull of the Earth.Newton's second law is F = maForce = mass x accelerationWeight = mass x acceleration due to gravityW = 50 kg x 9.8 m/s2 (Force or Weight has a unit of Newtons, N)= 490 NWhy? Perhaps because when we use the balance or the weighing machine we are using gravity but then we convert the scale back to mass.
Weight and mass are only related by the gravitational constant between them. In the SI system, that constant is 9.8 m/s2. In the English system, this is 32 ft/s2. Weight is a force that gravity exerts on a mass. Mass is the amount of matter contained within an object. It is a common misconception that these are the same. They are two completely different quantities in the eyes of a scientist.
The mass of any object is its attraction by gravity. If the ball is attracted by gravity, and the attraction is measured by scales, we might say that the ball has a weight of five kilograms, or a mass of five kilograms. We can put it another way by saying that mass is the property of a body that causes it to have weight in a gravitational field.
