What is a scientific definition for the word "mass."

Note: This CAN NOT be from a normal dictionary. I need a SCIENTIFIC definition.

Thanks a bunch!

"8. Physics. the quantity of matter as determined from its weight or from Newton's second law of motion."

From Dictionary.com.

In scientific terms, mass is defined as the quantity of matter contained in an object. It is a fundamental property of matter and is typically measured in kilograms (kg) or other appropriate units. Mass is independent of gravity and does not change with the object's location or environment. It is different from weight, which is the force exerted on an object due to gravity and can vary depending on the strength of the gravitational field.

In scientific terms, mass is defined as a fundamental property of matter. It is a measure of the amount of matter present in an object, and it determines the object's resistance to changes in motion. The scientific definition of mass can be obtained from reputable scientific sources, such as textbooks or scientific literature. To find a scientific definition for the word "mass," you can follow these steps:

1. Identify trusted scientific sources: Look for reputable scientific publications, textbooks, or online resources that specialize in physics or physical sciences. Examples of trusted sources include textbooks written by renowned physicists, scientific journals like Physical Review Letters, or educational websites endorsed by academic institutions or scientific organizations.

2. Access the scientific source: Find the selected scientific source either physically (in a library or bookstore) or digitally (online libraries, databases, or journal websites). Some sources may require a subscription or access through an educational institution.

3. Navigate to the appropriate section: Once you have obtained the scientific source, determine the section or chapter that is likely to discuss mass or fundamental properties of matter. This could be a chapter on basic principles of physics, mechanics, or introductory physics concepts.

4. Locate the definition: Read through the relevant section or chapter carefully, looking for a definition or explanation of mass. Pay attention to how mass is defined, what units it is measured in (usually kilograms in the International System of Units), and any additional information or concepts mentioned in connection with mass.

5. Gather relevant information: Take notes or make a mental summary of the scientific definition of mass. Ensure that you understand the key points and concepts mentioned in the definition.

It's important to note that scientific definitions can vary slightly depending on the source, but the general concept of mass as the measure of matter and resistance to changes in motion remains consistent.
