In the chapter where Jiyoung explains force control to Jiwoo it is stated that force control is (or at least was originally) a way to improve your power and efficiency with your ability. After the original force control was invented, different people started altering the force control to fit them better. In modern day, the heads of families and associations teach different levels of force control to each member based on their importance to the family/association. In Jisuk's and Jiyoung's case their wind ability is most likely hereditary and force control allows them to make their ability more powerful and efficient. Jiyoung as the chairwoman of Shinhwa teaches force control to Shinhwa's members and it is stated more than once that Shinhwa's force control teaches members how to control wind with their awakened power.
Jiwoo has acquired electrical attributes because Kayden taught him his force control, a second instance that suggests force control CAN pass down attributes.
In the first chapters of the story (Chapter 4) we learn from Kayden that awakened powers can take either a physical or psychic form. We also learn that powers can be developed in many ways. Jiwoo's powers are physical and Kayden states that he may even be able to do things other than super speed, though we haven't seen anything else other than the electrical attribute from him yet.
Other than that, before Jiwoo's first fight with Jisuk, Kayden teaches him to collect his energy in one spot for a single hit that will catch Jisuk off-guard which suggests that Awakeners have a special energy inside them and Force Control allows them to control it in various ways.
One more thing I'd like to note is that there are many instances where characters say Awakeners can have more than 1 abilities through proper training, which could perhaps be learning a different kind of medium to high level force control, and although it's not common, it's not impossible for someone to have more than 1 ability.
Last but not least, in the recent chapters, Curtin (and in earlier chapters, Kayden) states that the possibilities of Awakened Powers are endless and we can see this with abilities like Transformation and Spacial Isolation. To me, personally, this suggests that awakened powers grant the awakener superhuman CAPABILITIES(Speed, Defense, Stamina, Strength, Reflexes) and not ABILITIES(Wind Control, Gravity Control, Telekinesis) but abilities are taught. Wooin's case also lead me to this thought since the owner of the orphanage he grew up in stated that he was faster and stronger than even adults and Seongha Park from the Union states that Wooin picked up Dr. Delein's unique style of using his powers, as in Telekinesis is the ability Wooin got from Dr. Delein's training and without Wooin was just stronger and faster than the average person because he is awakened (Wooin vs Jisuk) (Recent Chapters). I think when someone in Eleceed's universe says "Their Ability" they mean it like "The Ability they USE" and not "The Ability that Manifested".
I am marking everything as a spoiler for obvious reasons so read at your own risk.
