Chapter 1, Problem 11STP

Interpretation Introduction

Interpretation:

The reason due to which scientists use mass instead of weight for their measurement needs to be explained.

Concept introduction:

The action of measuring the size or quantity of anything is defined as a measurement. A substance is a pure form of matter or element or compound.

Answer to Problem 11STP

Mass is usually told that how much matter is present in the object whereas, weight is about gravitational pull. So, mass is preferred by scientists.

Explanation of Solution

A measure of matter's amount constituting the physical body is defined as mass. It is usually estimated by how much anything weighs. It is measured in kilograms grams, and, tones (Metric)/ounces and US units (Pounds).

Weight is the measure of the stretch of gravity on a particular object. It is measured on a different scale. It does change with change in the location of an object.

Scientists use mass instead of weight for their measurement because mass is a measurement of object’s amount whereas, weight is described as a measurement of the gravitational pull.

Conclusion

Scientists use mass instead of weight for their measurement because mass is a measurement of object’s amount.
