  1. Weight vs. Mass

  2. Some Key Terms • Matter: is anything that has mass and takes up space. • Mass: the amount of matter in an object. • Measured in grams or kilograms. • Mass is not the Same as Weight • Weight: mass of an object times gravity

  3. Mass vs Weight MASS Weight Depends on gravity and mass. Weight = mass x gravity. Weight changes as gravity changes. • The amount of matter in an object • Mass is constant no matter where you are.

  4. On a mountain you would weigh slightly less.
