Potentially yes, and maybe wormholes need a minimum amount of energy to open that is greater than the gravitational delta between the 2 locations (hence making them in similar locations in spacetime being the lowest energy cost, a good reason for gates to exist over a mobile/onboard system). It may also be that there is an energy penalty for traversing through wormholes that is equivalent to any kinetic energy gain that would have happened.

Edit: Lol, I thought I was in r/worldbuilding, whoops.
