Kamehameha on the other hand is also a high concentration of Ki in a form of a medium-sized beam, that is supposed to either push it's target away or completely anihilate it. It can also blow up moons as shown in original Dragon Ball series by Muten Roshi during Tenkaichi Tournament.
Final Flash - just like Kamehameha, but looks like it's the power of Super Saiyan form concentrated and fired as a monster-sized beam.
As to Ki releases on punches .....
There are 2 possibilities:
1) They are using Ki to accelerate the speed of their punches and to reinforce their body, which leads to increased power ..... something like releasing it from the back of their hands to accelerate ?
2) They are using Ki to directly increase the damage of their punches of their fists and to reinforce their body ..... releasing it from the front in a form of small explosions ?
Was it ever explained HOW they are using their Ki to increase their power ? I do remember Piccolo talking about that to android Dr. Gero or Cell, but if memory serves me well it was along the line of "we release our Ki in short bursts to increase our power" ..... or something like that.
