Title: Mass Versus Weight


1
Mass Versus Weight
2
Mass
  • Mass is the quantity of matter in an object.
  • Mass is one of the properties of matter this
    means that we can describe matter by measuring
    its mass.
  • We use a triple-beam balance to measure mass.
  • Mass is measured in grams, or any metric
    conversion of a gram.

3
Weight
  • Weight is another property of matter this means
    that we can describe matter by measuring its
    weight.
  • Although we use the word weight in everyday
    language to refer to how many pounds and ounces
    something is, what we are really referring to is
    the objects mass.
  • In science, weight is not the same thing as mass.

4
  • Weight is the product of the objects mass and
    the effects of gravity.
  • Weight is a Force!
  • Because weight is a force, it is measured using a
    spring scale and measured in Newtons.

5
  • The force of gravity is the attractive force, or
    pull, between the earth and all other objects.
  • Because gravity is a force, and it affects an
    objects weight, weight is a force as well!
  • The closer to the surface of the earth an object
    is, the stronger the gravitational attraction on
    the object.

6
What happens to the weight of an object as it
moves away from the Earth?
7
  • The force of attraction between the object and
    the Earth decreases and thus the objects weight
    becomes less.
  • Keep in mind, the matter that makes up the object
    is still present, and unchanged.
  • All the same atoms and molecules are there,
    arranged in the same size and shape so the
    objects mass does not change.
