comment The elusive difference between impulse and momentum
@Alb, you also asked "Where did I go wrong?" which I quoted and addressed. If you aren't clear on the concept of acceleration, which is evidently the case, then this must be addressed first before we can attend to your other questions. I've updated my answer to address your latest update and question on acceleration.

@bobie, do you mean the question "Where did I go wrong?"

comment What is zero impedance in AC circuit?
@XiangruLian, I updated my answer though I'm not sure if this completely addresses your concern. That might be the topic of another question.

comment Picturing Feynman's argument about perpetual motion
@Bardo, once a mass has been raised, it can be attached to another machine, e.g., moved horizontally to another pan or attached to a different rope. Think of it this crude way: machine B lowers M and raises 3M where the weights are secured and machine B 'moved out of the way'. Then another machine is connected to 3M and gravity does work on this machine as the weight is lowered. 3M is secured and this machine is 'moved out of the way' and machine A is connected to allow the weights to come back to the zero height.

comment If parallel universes actually existed, wouldn't there be a universe where parallel universes didn't exist?
This is why I dislike the notion of multiple universes. Now, it appears, your thinking of parallel multiverses within some metamultiverse which contains some multiverses without multiple universes. Why stop there? Let's come up with the Matryoshkaverse.
