minus-squarelemmyman@lemmy.worldlinkfedilinkEnglisharrow-up9·edit-219 hours agoEscape velocity does scale with (square root of) radius so its not a dumb thought. And I’m not a rocket surgeon but I could imagine earth rockets might be operating near some physical limits that make a 50% increase (or whatever) infeasible. https://en.wikipedia.org/wiki/Escape_velocity
minus-squareLojcs@piefed.sociallinkfedilinkEnglisharrow-up3·edit-218 hours agoWikipedia says energy = GMm/r. if g=GM/r² then energy = mgr, proportional to r given g is constant. apologies My previous comment was wrong, I derivated while integrating.
