WHAKAMĀRAMA

Ko te ngoi o roto i te neke o tētahi mea. E whai ānga ana tētahi mea mēnā e neke ana. Ko tōna papatipu me tōna tere whaiahu hei tohu i te ānga. Mēnā he taumaha te mea e neke ana, he nui anō tōna ānga, ā, he uaua te whakatū. Mēnā he tere te neke, ka piki anō te ānga. 

The strength or energy in the movement of an object. An object has momentum if it is moving. The mass and velocity of the object determines its momentum. If a moving object is heavy it has greater momentum and is more difficult to stop. An object moving at high speed also has greater momentum. 

Tauira KŌrero

He aha ngā inenga e hiahiatia ana hei tātai i te ānga o tētahi motukā?

Ina tukia ētahi motukā e rua, ko te ānga o aua motukā hei tohu i te tārukenga ka hua ake.

E tika ana kia whakaaturia te ahunga o te ānga.

Ina tukia tētahi mea e tētahi atu, ka whakawhitia te ānga o tētahi ki tētahi. Hei tauira, mēnā e noho ngū ana te pōro kahurangi, ā, ka tukia e te pōro mā, ka whakawhitia tētahi wāhanga o te ānga o te pōro mā hei whakanekeneke i te pōro kahurangi. Ka noho pūmau te rahi o te katoa o te ānga i mua, i muri hoki i te tukinga. Arā te whārite:

E tātaihia ai te ānga o tētahi mea, me whakarea te papatipu (kg) ki te tere whaiahu. Arā te ture tātai:
ānga = papatipu x tere whaiahu

Ka hua ake te waeine mō te ānga i ngā taurangi e rua nei, te papatipu me te tere whaiahu.

Hei tauira, mēnā 1200kg te taumaha o tētahi motukā, ā, e 50km/h tōna tere, ko te 1200 x 50 = 60,000kg/km/h te ānga.
