# I Do charges accelerate because their field lines are changed?

I ask this because of this diagram.

Say that two charges are held a certain distance apart and are let go. Well, we see that the field lines of one charge repels the other.

And I noticed that the field lines for an accelerating charge also bends.

So can we say that because one field changes the geometric configuration of the other field, the other charge must accelerate to accompany that change?

I know the formal definition involves charges(F=qE), but I want to know if it can be viewed from another perspective.

I guess you could think of it in a way that states that a particle wants to return to its natural configuration with all field lines point straight outward/innward. So it seeks that natural state by moving. That definitely isn't an official law or anything but it definitely gets the idea across. But that wouldn't describe opposite charges.
