I appreciate all the feedback! I'm not a soccer player and my oldest child developed kicking quickly by me just repeating what the coaches said. I've looked at a lot of videos trying to understand the technique. It appears her passes were more power because she locked her foot while passing but not when kicking. So, we have been working on her technique not distance right now and she has made some improvements. Thanks again everyone!

Velocity is a function of force maximally applied to ball
Messi may have less force than others (doubtful) but he applies a greater % (compared to others) of his generated force to the all via technique.
Either your girl can apply force to striking ball or not. You say she can withnoassing but not kicking.
Makes no sense.
In assumption you mean she passes with velocoty with inside of foot but does not strike well with laces ...
Well practice. They really 2 different physical acts.

Practice striking a heavy bag just laid on floor.
By this u remove the focus on accuracy on striking a ball and just train the body to strike forcefully
Then use a ball and. Work. On accuracy

Honestly I think U should just let it happen for her and not worry
