Nā anakahi i loaʻa

ʻOiai nā ana o nā ana i hoʻonohonoho ʻia e hoʻoholo i ka nui o nā mea i hiki ʻole ke helu ʻia mai ka 'helu o kēlā me kēia anakahi', ʻO nā anakuhi i loaʻa nā mea i loaʻa mai nā ana o ke ana, a noi ʻia no kekahi mau kikoʻī kikoʻī.

Kahi ana o ka lōʻihi (ka mika), kekahi o nā nuipa (ke kilo), hoʻokahi manawa (ka lua), kekahi o nā uila (ka ampere), kekahi o ka mahana (ke kelvin), kekahi o nā mea ( ka mole), a me kekahi o nā ʻāpana māmā (candela). Mai kēia mau ʻehiku hiki ke hana i kahi hui i pau i ka pae ʻana i kekahi o nā anakahi i lawe ʻia, pono no ke ana ʻana i kekahi papa o nā phenomena. ʻOiai ʻaʻole lākou nā anakahi o ke kumu, he koʻikoʻi nui lākou no ka lāhui kanaka: Me ka loaʻa ʻole o nā anakahi, ʻaʻole hiki ke ana ʻia ka ikaika, ka ikehu, kaomi, ka mana, ka wikiwiki a me ka wikiwiki.

E like me nā ʻāpana maʻamau o ke ana, hāʻawi nā ʻāpana i loaʻa i ka hiki ke hana i nā hoʻololi ʻana ma waena o nā ʻano ʻokoʻa. ʻO kahi laʻana, he mea maʻamau ia no ka ana o ke ana ʻo 'Newton' e hoʻohana ʻia ai e ana i ka nui o ka ikaika, akā aia kekahi anakahi o ke ana ʻo 'Dina', ma lalo o ka pilina ma kahi o 1 newton i like me 100,000 dynes. Hana ʻia ka mea like me ke ana o ka ikehu, ka hana a me ka wela: hoʻohana ʻia ʻo Joule i ka ʻepekema sphere, akā hoʻohana ʻia nā calorie i kēlā me kēia ola. ʻO ka pilina ka laina, a ʻo kahi calorie he 4.181 joules.

Aia i ka papa inoa aʻe he ʻumikūmālima mau laʻana o nā anakahi i loaʻa, e hōʻike ana i nā mea a lākou e hōʻike ai, a me ka hui pū ʻana o nā anakahi ana o ka ana e hoʻoholo ai iā lākou.
