Medium entrainment considered as flow

Bart,

What are your medium particles made of?

Yes it does. Yes it is. How does Earth's gravitational force get to Luna, so it can cause Luna to accelerate?

LB, You asked the same question several times and my answer is still the same(I don't know). However, maybe the question is trivial in that a force can and will be move only when it's source changes in some manner. So, in order to understand how gravity works maybe you need to know why the source has that property. If you simply say force and energy are equal you miss a lot of fine detail that is very important if any progress is to be made here. Force is totally different than energy. Maybe you could write a model like: F=ma that would show how gravity is something other than a force. We have no model for the force of the photon and that is needed too. E=mc^2 ignores photon force-so does E=hf. That is a big hole in the middle of our field don't you think?

You don't know? Since I've given you the answer several times (even drew a picture once), you must mean that you don't understand.

That can be your fault, or mine, or both. Let me think about this a little and see if I can find another way to explain the relationship between energy and force.

<b>[Jim] "Maybe you could write a model like: F=ma that would show how gravity is something other than a force."</b>

Here you say "... show how gravity is something other than ..."

I am trying to show you that gravity can be viewed in more than one way. It is not something "other than" force.
<ul>
<li>It is energy (kinetic and/or potential).</li>
<li>It is force.</li>
<li>It is acceleration.</li>
<li></li>
<li>It is not potential. (Force " " "is" " " energy. Force is not potential.)</li>
<ul><li>The physical potential field is involved with observable physical things like light bending and clock slowing.</li>
<li>It is not involved with observable physical things like force and acceleration.</li>
</ul>

</ul>
(Hmmm. Do not read the word 'is' as the equivalent of an equal sign. Use some caution if you feel like reading 'is not' as its mathematical equivalent. This is not really so much about math.)

Which way you pick to look at it depends mostly on the problem or the question you have before you, but can also be influenced by your personal preferences (for problem solving).

So, you say gravity changes to suit the problem at hand? Gravity can be a force; or it might be energy if the problem needs that; or at times it can be acceleration. Don't forget energy radiates and gravity does not. Remember acceleration is induced by a force and is not the force. I looked at your connections and still don't see where energy and gravity interchange as you simply indicate gravity forces particles to react. You haven't explained energy or force by confusing them with each other.
