What is the difference between a law and a theory?
A A law is a natural phenomenon about which competent
observers can agree; a theory is a general statement about the
relationship of natural quantities that has been tested over and
over again and has not been contradicted.
B A law is the synthesis of a large body of
information that encompasses well-tested hypotheses about certain
aspects of the natural world; a theory is a general hypothesis that
has been tested over and over again and has not been
contradicted.
C A law is a general hypothesis that has been tested
over and over again and has not been contradicted; a theory is the
synthesis of a large body of information that encompasses
well-tested hypotheses about certain aspects of the natural
world.
D A law is the synthesis of a large body of
information that encompasses well-tested hypotheses about certain
aspects of the natural world; a theory is an educated guess which
can be tested by experiment.
