  1. Mass Notes

  2. Matter • The amount of stuff in the material.

  3. Mass • the amount of matter in the object • Mass never varies or changes. It remains constant

  4. Example • If you travel to the moon, the amount of matter in your body (your mass) does not change.

  5. Weight • The measure of the force of gravity on you • Mass is not the same as weight

  6. Mass vs. Weight • Unlike weight, mass does not change with location, even when the force of gravity on an object changes.

  7. On the moon you would only weigh one-sixth of your weight on Earth • Weight on moon = .16 x your weight on Earth • Your mass would remain the same

  8. Units of Mass • mg – milligram • g – gram • kg - kilogram

  9. Measuring Mass • A triple beam balance is used to measure mass • Electronic balance

  10. Volume • The amount of space an object occupies

  11. Volume is a property of an object • Solids, liquids and gases all have volume

  12. Volume – unlike mass can change under certain conditions

  13. Liquid Volume • L – litermL – milliliter • Volume of solid objects: cm3 – cubic centimeter

  14. Calculating Volume • Regular Solid Object: • Volume = length x width x height • V= l x w x h • Units: cm x cm x cm = cm3

  15. Liquid Volume • Tool = graduated cylinder
