Stoat,
I think our answer is in the correct interpretation of coulombs law:
a particle is energy in motion. A force is the result of energy's action.
en.wikipedia.org/wiki/Coulomb's_law
can we change the equation F=ma ?

Here is another hint on the varying Planck's constant (in alpha):
-(Quantum Electro Dynamics)-
"If a beta-function is positive, the corresponding coupling increases with increasing energy. An example is quantum electrodynamics (QED), where one finds by using perturbation theory that the beta-function is positive. In particular, at low energies, ¦Á ¡Ö 1/137, whereas at the scale of the Z boson, about 90 GeV, one measures ¦Á ¡Ö 1/127.
Moreover, the perturbative beta-function tells us that the coupling continues to increase, and QED becomes strongly coupled at high energy. In fact the coupling apparently becomes infinite at some finite energy. This phenomenon was first noted by Lev Landau, and is called the Landau pole. However, one cannot expect the perturbative beta-function to give accurate results at strong coupling, and so it is likely that the Landau pole is an artefact of applying perturbation theory in a situation where it is no longer valid. <b>The true scaling behaviour of ¦Á at large energies is not known.</b>"

Hi GD, but therein lies the problem. Say one's in a flying saucer and the host shows a huge moving spaceship, through the windscreen. He/she gravely announces, that it's being towed by tugboats. Primitive earthlings would use two tugs, which could pull at varying forces and directions. The big ships movement then being the resultant of the two tug's vectors.
Then he, smugly, says that they use an infinite number of tugs, and that's why they are so superior to your pathetic species. Of course one laughs out loud but then notices that there's only one laughing. All of Earth's leaders have been totally bewitched by such total control of space and time, that they are offering their most comely daughters to the clever alien visitors.
Depressed, go to the pub. Where a drunk declares that he's not drunk but has to work out complex integrals in 27 dimensions to get to the bar. When you point out that they are not really necessary, he accuses you of being naive. He is pondering reality, whilst you are barely scratching the concept of existence.
So you rush home, you have in your book collection, a classical physics explanation of why the orbit of Mercury is as it is. When you get back the drunk has moved on to consider the problem of how to get to the bar, as involving the use of relativistic renormalizing techniques to n dimensional superstrings. He sneers at your few equations, his are much better. The government gives him money and huge machines to play with, and he gets to score with beautiful women.
So off you again and you learn all of this stuff. The resolute intention being to show this ship of fools the error of their ways. Much more likely is that you end up as a latter-day John Dee.
Sorry to sound so glum about things but sometimes I just want to throw in the towel and go off and do some oil painting instead.

A good idea does come along at some point. Anyhow, you bring up the Z-boson and can you say what it decays into? And where it comes from?

Hello Stoat,
I have a little story of my own:
Some alien on planet A (much closer to the sun) watches through a powerful telescope the meanderings of some other beings on planet B (approximately the same size as planet A but orbiting the sun much further away). He sees a rocket ship blast off from it's surface at incredible speed.
He thinks to himself: "I need one of those spiffy machines to go and visit these aliens (maybe get one of their daughters)". He gets in touch with a spy on planet B to have him copy the plans and technical data so that he may reproduce this "chariot-to-the-heavens" on his planet.
After much delay in the fabrication schedule partly because of the bad quality of the smuggled photographs, this marvelous piece of machinery is finally ready.
He clambers in the spaceship and fires the engines....
To his consternation, the rate of ascent is not the same as he observed through the telescope many months earlier. He soon realizes that he will not reach his target and aborts... he thinks: where did we go wrong! We did an exact copy...
Having already paid the spy, he feels he has been hoodwinked and humbugged.
Back on the ground, he goes to the pub, orders a glass of methane and still raging about the whole waste, he makes plans to have his informant shot.[8D][][^]
Why would it take more energy to move away from the sun radially than it is to orbit the sun?
See escape velocities from the planets with respect to the sun to exit the solar system (last column):
en.wikipedia.org/wiki/Escape_velocity
Is there something to do with available energy, time and distance that affects the speed of an object?
The escape velocities are calculated from the center of mass... a few posts back I mentioned that the energy's availability in a mass or system varies with respect to its center...

Stoat,
...Back to Coulomb's Law:
en.wikipedia.org/wiki/Coulomb's_law
Towards the end of the page, see: Table of Derived Quantities.
In the center of the table it shows the relationship between particle property and field property.
F=qE
My interpretation is: a particle (which is energy quanta) is affected by the energy field it is situated in.
Force is the result of energy's interaction.
Can we replace "Force" by "Energy's interaction" ?
