Consider:
A "theory" which simply states,
"There is an attractive force between objects, the strength of which
depends only on the masses of the objects and the distance between
them. It is stronger for objects with larger masses, and gets weaker
as the objects are moved farther apart."
is useless. It does not even tell us that if I let go of a ball, that
the ball will fall to the ground. My hand is closer to the ball, and
according to the above "theory," because it is much closer to the ball
than the earth is, its gravitational force might be stronger than the
earth's even though it is not as massive, and the ball might fall back
up into the hand I tried to drop it with.
Any physical theory must be quantitative if it is to be of any use at
all. Like Newton's gravitational theory, which tells us how we can
calculate the gravitational force between two objects,
Force = gravitational constant * mass 1 * mass 2 / distance^2
a useful theory must give us some way, even if it is an approximate
one, of calculating how large the effects it predicts are. Otherwise,
you have no way of distinguishing between the gravitational force the
earth exerts on the ball, and the gravitational force my hand exerts on
the ball. The only difference between the two is that one is several
billion times stronger than the other.
