Factual error: Martha Kent drives away from the foreclosed property. The realtor address is "Comanche, KS 66531", but that's the zip code of Riley, in Riley County. (00:06:30)
Factual error: The existing Justice League members realise that they cannot battle Steppenwolf without Superman, so they procure the last Motherbox to resurrect Superman from death. Unfortunately, the crippled Kryptonian spacecraft lacks sufficient power to activate the Motherbox. The Flash suggests that, given enough distance to accelerate, he can use his super speed to generate an enormous static electrical charge to activate the Motherbox. The problem with this scenario is that, although the Flash may generate a huge static electrical field at super speed, he is constantly discharging that static electricity, as we see every single time he exerts his power. As Flash races toward the Motherbox, gigantic arcs of electricity (easily hundreds of thousands of volts) pour off him, grounding to the spacecraft's bulkheads, thus neutralizing the static charge. Meaning that The Flash is not accumulating energy, he is discharging energy with every step; so, by the time he arrives at the Motherbox, he should have no more accumulated static electrical energy than if he started ten feet away from it.
Suggested correction: Under known physics, you are correct, however, The Flash can tap into the speed force, something that transcends known physics, which therefore makes his charging of the motherbox possible.
It doesn't matter what he is "tapping into" if he is still grounding-out to the ship's bulkheads and is discharging electricity the whole time.
Also the bulkheads are made of Kryptonian technology, being alien in nature maybe the discharged energy reacts differently and perhaps is reflected back into the Flash at a rate so fast that is imperceptible to the human eye. Like Bruce said the mother box is science beyond anything imaginable so we have to keep our mind open to possibilities regarding its properties.
Sorry but you are incorrect. According to you Barry shouldn't be able to run at all at high speed because physics. The speed force may as well be magic, as it defies physics in multiple ways i.e friction, gaining momentum the requirement for an equal opposite force to come to a rapid stop etc. Nevermind that it's canonical that they can generate and hurl lightning bolts.
Suggested correction: He said that he can "conduct a significant electrical current." At the moment he touches the cube, you can see the bolts sucking back into him and flowing into the cube. Also..."speed force."
