Hence the true equation is as I have said Work done = Distance x Mass x Acceleration (frequently G). In space (free of fields) this still applies. The acceleration is whatever is imparted to the mass over the particular distance.
It's something that most people intuit, but apparently you don't. This "intuition" has allowed most physics book writers to abbreviate what they mean to the point where it's possible to misunderstand them.
It really should be obvious to you that pushing or lifting an object twice as heavy as another object should involve twice as much work. More obvious, surely, than suddenly imagining you had discovered a new branch of physics.
In your options, the second requires twice as much work as the first.
And you're still as wrong as you were before. You aren't reading what I'm writing.
You may think what you like. If you're in a permanent mess because you can't see it any other way, this will be quite to my taste.

I like seeing hubris in others.
You're just trying to cloud the issue now.

Also you have just contradicted what you previously claimed. Earlier you said it was W.D. = Force x Mass x Distance and now its W.D. = Distance x Mass x Acceleration.

Make your mind up JazzRoc.

Anyway your last equation still doesn't satisfactorily explain my example. The mass is fixed as is the force pushing the weights. And I don't dispute that the acceleration is different for each weight.

Looks like I've got you on the run JazzRoc.
