No bell ringer, arrange your folders and turn in.

  • Folders due

  • P.401 and 402 due

    • Notes - rearranging equations

      • Goal is to get an equation into the format of (wanted variable) = ____________

      • Use opposite functions to move variables around in an equation

      • Will need to do this with equations from now on

    • Notes - mass and weight

      • Mass

        • The measure of the amount of matter that makes up something

        • related to the number of atoms in an object

        • measured in kg

        • measured using a balance

        • Does not depend on gravity (or, therefore, location)

      • Weight

        • The measure of the force from gravity on an object

        • Depends on the size of the object and the amount of gravity

        • Measured in N (since it is a force)

        • Can be changed by going to a place with more or less gravity (changing altitude on Earth, going to the moon or another planet)

  • Mass and Weight Lab (due Tuesday)
