Examining Spatial Acceleration and the Acceleration of Gravity

    Acceleration is defined in elementary mathematics and physics texts as the
rate of change of the rate of change of position with respect to time.
Mathematically expressed, it is the second derivative of position with respect
to time. Elementary physics texts assert that in order for a material object to
undergo an acceleration, a force must be applied in accordance with the
expression force(F)= mass(M)*acceleration(A). (Physics 101).

    When applied to linear motion, the conclusions are straightforward. The
application of a net force to a mass causes its velocity to change at a rate
which is in proportion to the ratio of the applied force to the mass. The force
you feel applied to your back when you press hard on the accelerator of a
powerful car is an example.

    It is when we consider what we experience as the "Force of Gravity" that
the intellectual confusion occurs. As you sit in your chair reading this you
experience a force as the chair presses against.  This force is commonly called
by the misnomer the "acceleration of gravity" and many modern physicists assert
that what you experience as a force really is an acceleration.

    The validity of this viewpoint is readily challenged by a recognition
that, except for minor effects, effectively you are not undergoing spatial
acceleration. Other than the force of the Earth's gravity, the only forces
affecting you result from the rotation of the Earth and the net gravitational
attraction of all of the other masses in the universe. Of these forces, only
those produced by the gravitational attraction of the Sun and the Moon and the
inertial acceleration due to the Earth's rotation have any significance. Since
these forces resulting from those accelerations do not exceed 0.3% of the force
you experience as you sit, they may be ignored in this discussion. Obviously,
what we experience as the force of gravity is a real force and not the result
of an acceleration in some postulated velocity reference frame.

    When unrestrained in whole or in part, the force of gravity produces a
spatial acceleration. It is this acceleration which is falsely asserted to be
the acceleration of gravity. In reality it is the acceleration produced by the
unrestrained or partially restrained force of gravity. Contrary to the
conclusions which seem to follow from General Relativity,  
what we experience as gravity does not result from a curved geometry. There is
no way that geometry can produce a force any more than the curved geometry of
the Earth's surface can propel a wagon along a level plain.
It is time to go back to the theoretical drawing board.

    The acceleration of gravity only occurs only when you are no longer
supported. In this state the force of gravity pulls you toward the center of
the Earth with a constant force which is resisted by the force needed to
accelerate you. Since these forces act on every particle of your body, as you
should expect, you do not sense this force.
