Yes in the linear case there need be no acceleration.

In the rotating case you cant do without it.

No, the Radius term is just missing in pC being 1 for E = MC2 + pC

Which would be the radius from the observer frame R or l, which is 1 in linear but in angular is not always 1.

Which does require an acceleration to do, but is not the reason why.

Is it really different besides being over a radius?

Yes, it is really different. Were you to actually try and apply the concepts in solving physics problems, it would become obvious.

That's not a valid equation.

I'll take that bet calculate for Linear Momentum  E1 = MC + PC , where R = 1, then do the same for angular momentum and see if it is different when E2 = MC2 + PC  , P = RL , L = Iω , I = MR2  you will find E1 = E2

E = MC + PC is not a valid equation (i.e. it does not hold true in general), and of what value would an equation be that's only valid for R=1?

I just rooted the entire equation to not have to type all the exponents E2  = M2C4 + p2C either way.

Then you did it incorrectly.  (MC+ PC)2 ≠ M2C4 + P2C2

i.e. there is a missing cross-term of 2MPC2

Damn it, I don't care which way you do it, it will be the same as long as R = 1 on Angular, but yes I typed that quickly but it does not  (MC+ PC)2 ≠ M2C4 + P2C2

It happens when addressing multiple threads at once constantly hearing PING PING PING PING, Medvil does severe multiforuming and tasking, but yes use E2M2C4 + P2C2    or your answer will be wrong, but it would not matter as both sides were by the same amount wrong so it would be right for the E1 = E2 scenario either way.

It will actually matter a great deal. 

Is R 1 meter, or 1 cm, or 1 foot? (which only begins to illuminate why the claim doesn't work)

Meters obvious but just use the correct form.

It's not obvious. If it only works in one unit system then it's a happy accident, and not something that's universally true.

Well, for that E2  = M2C4 + p2C2  

It only works at one point but for other kinematics equations universally true.

Prove it.

MV = p , p = R x L, L = I ω  , I = MR2  ω = V/R
