    What is the meaning of proportional and how is it used in different contexts?

    ^ freudian slip. Stop mixing up your physicists and psychologists... unless your comment was in irony and I missed it? =P As for an easy way to think about proportionality: as x increases, so does y AT A CONSTANT RATE So time taken for a falling object to hit the floor is proportional to the...
