Yea, its all based on super speed, but lets break it down. The Flash doesn't just move fast, he does everything at superspeed. He even thinks at superspeed. All the speedsters do. Its how Bart Allen was able to read all the books in the Keystone Library in just a few days. Flash thinks so fast, it makes relative time slow down. Its as if the rest of the world is going in super slow motion. He also heals at super speed. In Flash # 219 & WonderWoman # 214, the two are paired up against Zoom and the Cheetah. Cheetah has been given superspeed (temporarily) by Zoom. Wonder Woman chases after Zoom & her thought bubble says that she's worried about the Flash (the Cheetah had ripped out his throat with her claws) ,."... but not too worried. He heals as fast as he does everything else. " In the next few panels, the Flash's wound, wich would be fatal to any normal person, is already healed up without so much as a scar. Wolverine, eat your heart out. Lets not forget all the other fun little tricks. Vibrating fast enough to phase thru solid matter, travel to parrallel dimensions, become temporarily invisible, and of course, make things explode. He can also run fast enough to time travel. Barry needed the cosmic treadmill, but Wally just needed the love of his woman. He can whip his arms around in a circle fast enough to generate little tornados. If he wants to make a big one, he just runs around in a circle. Barry used to do this alot. Because of Wally's encounters with the speed-force, he also has the power to lend or syphon off speed-energy from any other person or thing. Its how he put Inertia in a state of suspended animation. He doesn't even have to touch the other person to do this, just get sorta close to them. This is why I think Flash would probably win in a fight against SuperMan, & not just a race. Can't win a fight if you can't move.
Cheetah wasn't given super speed by Zoom. She always had super speed, he just helped her (perminently) become a little more driven.
I don't know why everybody says Zoom gave her super speed. He flat out refused to.
Flash Fact: Doctor Barbara Ann Minerva is actually the third Cheetah, but the second, Debbie Domaine, was retconned out of existance (as the Cheetah, Debbie still exists as a civilian) by the Crisis on Infinite Earths.
