"Is There a Force of Gravity?"

In undergraduate physics, the Newtonian concept of an attractive force
between masses that is proportional to the product of the masses divided
by the square of their separation is taught. When one advances to the more
advanced concepts of gravitational theory as posed by General Relativity,
the concept seems to change to where what we experience as a force is
really the result of an inertial acceleration in "space-time".

Well, actually things have moved on a bit since you were educated. In this
country, and very likely yours, for many years newtonian physics has been
taught for under 16 exams with basic concepts of special relativity for
under 18 exams, and general relativity is an undergraduate course.
