回答: 请教一下：怎样和四年级的孩子解释：mass 和 weight 的不同由 laolaoshishi 于 2016-02-23 16:51:14

To understand the differences we need to compare a few points:

1) Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object.

2) Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.

3) The Mass of an object doesn't change when an object's location changes. Weight, on the otherhand does change with location.
