Another Great Job. Aha! The key is that to the observer in an inertial frame of reference the force would remain the same, the mass would increase, and the acceleration would decrease. However to the observer of the dime, all three would be constant. You really helped. That math was great...

That's the ticket! Thank you, sir. A kind, accurate, and understanding response! I've taken the liberty of PMing my email address. Thanks again.

Thanks. But here's my problem: Since the dime is accelerating, that frame is not valid for inertially sound measurements. So... in reality this constantly accelerating dime needs exponentially increasing force (and therefore energy), right?

I have this "thought" experiment. Imagine a large rigid object, a thin disc (dime) with the ("heads") surface area of the earth, accelerating in the "heads" direction for many years such that individuals on the surface (of the "head" side) experience the normal sensation of "gravity". This...

I stand corrected on the beta particle. I wonder if you left out a word in this sentence: "No, I would say the forward-pulling force is "gravity"." Thanks.

Thanks! My heartfelt gratitude!

I'm not getting my question across. Do you agree with the claim "Gravitation is acceleration."? Is, for example, the "acceleration" of a beta particle and a thorium-234 away from the fission of a U-238 atom "gravitation". I say "no". Thanks for putting up with my late night miscommunication...

Okay. I agree, but ... If that's an answer to my request, you haven't help me in the least.

The Claim: "Gravitation is acceleration." Please help me understand. I'm struggling with this claim. I have a BA with a physics major (though 26 years ago), but I don't seem to be able win an argument about this claim. It's important to advancing our understanding, and I politely request your...
