Mass and weight are directly proportional to each other.
Weight increases as mass increases.
Weight decreases as mass decreases.

Explanation:

  • First we define a few terms:
    m := "mass of the object"
    g := "acceleration due to gravity"
    F := "weight"
    now that we have defined the terms, we put them in equation form:
    -mg = F
    therefore,
    m prop F
    -
  • Alternatively, we can use Newton's Law of Universal Gravitation
    again we define a few terms:
    m := "mass of the object"
    M := "mass of the other object"
    G := "gravitational constant"
    r := "distance between the objects"
    F := "weight"
    then,
    -(GmM)/r^2 = F
    again,
    m prop F
    -
