[DC Comics/The Flash] So when the Flash accelerates, is he physically running faster, or is the speedforce allowing him to move farther in between his feet touching the ground?

I get it, I get it: speedforce. But does the speedforce allow him to physically run so fast that he can achieve the impossible velocities he does, or is how fast he's going independent of how quickly he moves his legs and instead entirely dependent on his vaguely psychic connection to the speedforce?

Does he just have to be doing a "pushing" motion with his legs, like skipping or leaping, in order to go fast, or could he potentially walk faster than the speed of light if he tapped into the speedforce enough?

Both/either because speedforce. 

The flash moves really fast, we have seen him do sidehops fast enough to rip a hole in this dimention.

But he has also moved really fast while his arms and legs move at walking speed (although that couod have been a poorly drawn optical effect).
