Recently I have learned about Mass and Weight.
Liquids, gases and solids, are all a type of matter. All matter has mass and weight. After watching the video clip Measuring Volume and the Mass of Matter, I know that all matter takes up space and all matter has a pull of gravity.
Weight is the gravitational pull on you. Mass isn't the same as weight because mass is how much space you take up. I know this because I watched the video segment Weight and Mass. It is a common mistake to mix up mass and weight. So remember that weight is the gravitational pull on you and that mass is how much space you take up.
