Thank you again Daniel, your reply was very informative and concise.
If you are not a physics professor in a university then you should be.

I had to read your reply twice before realizing where my error was.

I used the words "potential energy" to try and impress on the idea that the stationary object or mass does not have any kinetic form of energy, even though it may conceal a large amount of latent or "potential" for kinetic energy.
In other words the word energy when used by itself has the meaning of the word kinetic integrated with it. Perhaps a better way of indicating that concept would be to say that the Einstein's formula tells us that mass can be converted into kinetic energy.
If the mass is stationary in relation to its surroundings, then there may be a stress or a force or a pressure difference between it and its surroundings but one can not call that stress or force by the word energy if the above definition is accepted.

Sometimes a single word can be interpreted in different ways and it can lead to confusion about the issue at hand.

I was using the word force to explain an effect which might be better explained by the layman's word suction, or the words difference in pressures.

Pressure is described as: "Force applied uniformly over a surface, measured as force per unit of area."

The physics word force as described by my encyclopedia is a: "vector quantity that tends to produce an acceleration of a body in the direction of its application."

For such a force to initiate the falling of a rock down, after I have thrown it up, the force would need to be exerted from the top.

In both ideas the unwanted word force creeps into the equation.

But there is hope for the solution of the problem.
Back in 1738 another Daniel came up with a concept that as a moving fluid's speed increases, its pressure decreases.
I do not know if Mr. Bernoulli intended his formulas to be used for the explanation of the fundamentals of kinetic and potential (latent) energies. However, the formulas that he came up with are very good explanation of the behavior of mass in motion.
His principle states that the total energy in a steadily flowing fluid system is a constant along the flow path. An increase in the fluid's speed must therefore be matched by a decrease in its pressure.
There is a "flow" of photons in space, we already know that the speed of this flow is constant, if we consider space as the fluid that we are examining, then the speed of light becomes the constant that we can plug into Bernoulli's equations and by that method examine fields such as gravity, magnetism and electricity.

But I'm going off on a tangent, explaining gravity instead of the mass-energy equivalence.

I'll wait for your comment to this post before going further.

Bernoulli's Principle, in physics, concept that as a moving fluid's speed increases, its pressure decreases. Originally formulated in 1738 by Swiss mathematician and physicist Daniel Bernoulli, the principle states that the total energy in a steadily flowing fluid system is a constant along the flow path. An increase in the fluid's speed must therefore be matched by a decrease in its pressure.
