a quote from the wiki page on penny

" The swords are connected to her (and possibly operated by) the use of thin strings attached to the hilts. She can allow the swords to pull her around or anchor herself and use them pull large objects, including pulling down an airship in flight despite the mass and thrust power of the vehicle. Such feats seem to indicate enhanced strength as well as the ability to anchor herself in some to the terrain."

her weight probably doesn't matter
