Well, as for me there isn't much same words with different meaning for example: - краватка (UA) = галстук (RU) = tie - краватка (RU) = ліжко (UA) = small bed Some words have different gender: - собака (RU female) = собака (UA male) = dog There are lots of words with different spelling which has the same meaning: - карандаш (RU) = олівець (UA) = pencil I think Ukrainian has more influenced from western languages through its history: - фортеця (UA) = крепость (RU) = fortress - файно (UA) = хорошо (RU)= fine But of course many of Russian and Ukrainian words have the same roots but their derivation, suffix, ending are different.
