Explanation:
Mass and Weight
The well-known discussion between mass and weight, though being totally different physical magnitudes, the everyday language of people tend to confuse both terms. We'll group the answers into both categories:
Mass:
1.balance. The instrument used to measure the mass
4.amount of matter in an object. The main definition of mass
6.measured in grams. one of the international units of mass
8.never changes. being the amount of matter in an object, it's constant
10.remains the same when gravitational force changes
Weight:
2.spring scale. Uses the force on a spring to measure weight, which is a force
3.measure of the gravitational force exerted on an object
5.constant on Earth. The mass is also constant on Earth but it's also constant everywhere, so this option fits best to weight
7.changes when gravitational force changes
9.expressed in newtons because it's force
11.six times less on the moon than on Earth. The gravity on the moon is one-sixth that on the Earth, so we weigh one-sixth there.
