Why do scientist measure and record the masses of objects rather than their weights?

The mass of an object is a measure of the amount of matter it contains, the weight of an object is the force a mass imposes due to the gravity between it and another mass.

∙ 9y agoThere are two main reasons for doing so. One is that the mass of an object is, under normal circumstances, an unchanging characteristic if the object whereas the weight is the result of the gravitational force acting on the object. For example, in space, the object would still have its mass, but its weight would diminish to near zero. The other main reason is that for many laws in physics - particularly mechanics - it i the mass of the object that matters, not its weight.

Do objects with large masses have large weights?
yes
Do large objects with large masses always have large weights?
no
What are calibration weights used for?
Calibration weights are used to weigh things. They come in masses such as a 100g or 500 weight. They are used to exactly and accurately measure objects. They are placed on a scale and are then used to weigh the object.
Is an objects density the measure of the amount of matter in the object compared to known masses?
is an objects density the measure of the amount of matter in the object compared to known masses
Do objects that have large masses have large weights?
well if it has little mass it has little weight and if you have a lot of mass the possibility of it would be that it weights a lot
Do objects that are the same size fall at the same rate?
Yes. And objects with different sizes, masses, and weights also fall the same.
Do objects that have large masses always have large weights?
well if it has little mass it has little weight and if you have a lot of mass the possibility of it would be that it weights a lot
What does the metric system help scientists do?
measure objects, masses. and liquids.
An objects what is a measure of the amount of matter on the object compared to known masses?
mass
How do you find out how much matter an object has?
You measure its mass. The simplest way of doing that is to use a balance and standard masses ("weights").
Do all objects weigh the same amount when placed in a vaccum regardless of their mass?
No. In a vacuum, the weight of an object will be the product their mass, times the gravity. In other words, objects with different masses will have different weights.
Why there is no force of attraction between closer objects?
If you mean gravitational attraction, there is such a force between ANY two objects. The force depends on the distance (if two objects are closer, the attraction is stronger), and on the masses involved (if the masses are larger, the force is larger). The masses of "everyday" objects, for example two people, are so small (for the purposes of the gravitational force) that the force is hard to measure.
