Ua manaʻo ʻia he kino paʻa i haku ʻia me nā ʻāpana he nui, a ʻo ke kaumaha o kahi mea ka huina o nā kaumaha o kēlā me kēia ʻāpana e hana ana i ka mea. ʻO ke kikowaena o ke kaumaha he kiko ma luna o kahi mea kahi i manaʻo ʻia ai ua hoʻopaʻa ʻia ke kaumaha o nā ʻāpana āpau e hana ana i ka mea ma ia wahi.

Ua manaʻo ʻia ua haku ʻia kēlā me kēia kino paʻa me nā ʻāpana he nui, a ua like ka mamao o kēlā me kēia mai kekahi. Eia nō naʻe, no ka hoʻomaʻalahi ʻana i ka loaʻa ʻana o ke ʻano no ka hoʻoholo ʻana i ke kikowaena o ka nuipa, ua hana ʻia kahi hoʻomaʻalahi ma ka manaʻo ʻana he ʻelua wale nō ʻāpana o ke kino paʻa. Hiki ke kapa ʻia kēia mau ʻāpana ʻelua he ʻōnaehana kino paʻa.
m1 = ka nuipa o ka ʻāpana 1, m2 = ka nuipa o ka ʻāpana 2. Aia nā ʻāpana ʻelua ma ka axis-x. Aia ka ʻāpana 1 ma kahi mamao x1 mai ka axis-y a aia ka ʻāpana 2 ma kahi mamao x2 mai ke axis-y. Ua pōkole ʻia ke kikowaena o ka nuipa ʻo PM. Aia nā ʻāpana ʻelua ma ke axis-x, no laila ua kākau ʻia ke kikowaena o ka nuipa o nā ʻāpana ʻelua ʻo xPM.
m = m1 +m2 = ka nuipaʻa holoʻokoʻa o nā ʻāpana ʻelua. Inā m1 +m2 = m a laila aia ke kikowaena o ka nuipa ma waenakonu o nā ʻāpana ʻelua. Ma ke ʻano makemakika, hiki ke hoʻololi ʻia ka hoohalike i:
Inā ʻoi aku ka m1 ma mua o m2 a laila kokoke ke kikowaena iā m1. I ka ʻaoʻao ʻē aʻe, inā ʻoi aku ka m2 ma mua o m1 a laila kokoke ke kikowaena iā m2. Pili wale ke kaulike ma luna i hoʻokahi ana, kahi e kau ai ka ʻāpana ma kekahi o nā axis coordinate (ka axis-x).
Inā aia nā ʻāpana ʻelua i loko o kahi mokulele (2 ana) a laila hiki iā mākou ke hoʻohui i ka hoohalike kikowaena o ka nuipa no ka hoʻonohonoho y.
Ua kaupalena ʻia ke ʻano hana ma luna i ʻelua mau ʻāpana. Inā he nui aku nā ʻāpana, hiki iā mākou ke hoʻonui i ke ʻano hana.
