### "Matter: Mass and Weight"

today you will learn about "mass and weight."

What are the two properties that all types of matter including solids, liquids, and gases have in common? answer- The two properties that matter and solids, liquids, and gases have in common is volume and mass. It is volume and mass because matter is anything that has mass and takes of space or has volume. So therefor those are two common properties that matter including solids, liquids, and gases all have in common.

What is weight, and how does it differ from mass? answer- You may think that weight and mass are the same thing, well no. Weight is the pull of gravity between other masses. The way that weight differs from mass is that mass is the amount of matter or volume in an object and weight is the pull of gravity between other masses. So weight and mass are two different things.

How are mass and weight measured? answer- Mass and weight can be measured in different ways. Mass can be measured with a balance and in grams, weight on the other hand is measured in pounds and ounces and with a spring scale. So both mass and weight are measured in different ways.

Does changing the location of an object change it's mass or weight? answer- If you went to a different location your weight would change but your mass would stay the same. For example, if you went to the moon your weight would change because the gravity is different in the moon, but your mass would stay the same. Your mass would stay the same because your body wouldn't change. So yes your weight would change and your mass stay the same if you went to a different location.

How does the mass of an object compare to the mass of it's parts? answer-  The mass of an object does compare to all of it's parts. They compare because both the mass of an object and the mass of its parts are the same. They are both the same because every object has matter or volume and every whole has the same.
