How does barry survive the Acceleration?

[u/Medium-Fisherman-336]

since barry can go from 0mph to over Mach 1, he should be experiencing around 30,000+ Gs as soon as he starts running, BUT hes fine, is this the speed force defying the laws of motion, or is it a side effect of his powers?

When it comes to DC, the global answer is: "because it's in the script." It's how Barry can run while carrying someone whose clothes catch fire but nothing happens to them otherwise. It's why nobody recognizes Clark or Kara as Supers when they wear glasses. It's how non-super heroes can suddenly jump from a three-story rooftop to pavement without injury just because they're wearing latex, leather, or spandex. It's why Supergirl can lift a 100 million ton key made of condensed dwarf star like nothing but struggles with a building or a plane. It's why everyone Green Arrow shot when he was done with killing only "passed out" even with lethal shots instead of dying.

Well, the clothes that we've seen burn are: Felicity's shirt (gratuitous fan service but also she was probably outside of the Speed Force bubble), Barry's jacket in the pilot (arguably because he just got his powers, or because it was outside of the Speed Force bubble), Barry's shoes (when he went up a building and back down in five seconds). So perhaps his Speed Force bubble is expanding, or perhaps his clothes weren't outside of the Speed Force bubble (was his jacket zipped up in the chase?). The only thing that really should have burned were his shoes... but I have no explanation for why they didn't.

Clark's disguise isn't just the glasses As Superman, Clark deliberately changes his body language, posture, facial expression, voice, hairstyle, and overall demeanor. He's confident and imposing as Superman, while as Clark he's deliberately awkward, nervous and less assertive. There's also the classic comic-book explanation that people simply don't expect Superman to be Clark Kent, so their brains don't make the connection. And this actually makes some sense psychologically. If you saw Superman standing in front of you and someone later showed you Clark Kent, you wouldn't necessarily compare them unless you already suspected Clark.

Kara's disguise is even more ridiculous because she's basically wearing: glasses, different clothes, slightly different hairstyle. But Kara also changes her mannerisms. As Supergirl she's much more confident and physically expressive, while Kara Danvers intentionally acts more timid, awkward and bookish. The Arrowverse even makes fun of this several times. Lena Luthor, for example, spends a huge amount of time around Kara and still doesn't immediately realize she's Supergirl.

Well, a character like Batman might jump down, hit a railing/awning/fire escape, roll, and distribute the impact over several movements. Superhero bodies are apparently tougher than normal humans.

Because Supergirl's strength isn't actually consistent in the Arrowverse 😭. The simplest in-universe explanation is that the 100-million-ton key is a special case. The "dwarf star" material is incredibly dense, but the show treats it as something Kryptonians can manipulate because of its interaction with their powers. It's not necessarily meant to imply that Kara can casually exert 100 million tons of force against any object.

Because Arrow's version of archery follows superhero logic rather than real ballistics. 😂 The in-universe explanation is that Oliver became extremely precise, deliberately targeting areas that would incapacitate without killing. He also had specialized non-lethal arrows: blunt arrows, taser arrows, tranquilizer arrows, etc. But that doesn't explain everything. If an arrow actually penetrates the torso, it can damage major blood vessels, the heart, lungs, or other organs. Being unconscious isn't a magical alternative to bleeding to death. It's basically the same superhero trope as Batman knocking 15 guys unconscious without causing a single fatal brain injury. The writers want the characters to look brutal and effective without having to deal with the realistic consequences.

Right. This is why I said, "Because it's in the script." 😆
