Question

Decide whether each statement describes mass or weight.

1. measured in newtons
2. measured in kilograms
3. does not change when gravity changes
4. changes when gravity changes
5. the amount of matter in something
6. a gravitational force

Answer 1

Mass is the amount of matter in an object, measured in kilograms, and does not change with location. Weight is the gravitational force on an object, measured in newtons, and changes with the strength of gravity.

Step-by-step explanation:

The concepts of mass and weight are often confused, but they are distinct physical quantities. Mass is a measure of the amount of matter in an object, and is measured in kilograms. It is an intrinsic property that does not change regardless of the object's location in the universe.

Weight, however, is the measure of the gravitational force acting on an object, and is measured in newtons. Weight changes when the gravity acting on an object changes, which can happen if an object is moved to a location with different gravitational pull.

To directly answer the student's question:

1. measured in newtons: Weight
2. measured in kilograms: Mass
3. does not change when gravity changes: Mass
4. changes when gravity changes: Weight
5. the amount of matter in something: Mass
6. a gravitational force: Weight

Answer 2

Weight is measured in Newtons, mass is measured in kilograms, mass does not change when gravity changes; weight does, mass is the amount of matter in an object, and weight is a gravitational force
