WHAKAMĀRAMA

Ko te rerekē haere o te tere o tētahi mea i te takanga o te wā. Ko te waeine hei whakaatu i te tere ko te mita i te hākona (m/h), nō reira ko te waeine mō te whakatere ko te mita i te hākona (te tere) i ia hākona (m/h²). Mā te whakapā i tētahi tōpana e whakaterea ai tētahi mea.

A change in the velocity of an object over a time interval. Velocity is measured in metres per second, so the unit for acceleration is metres per second (speed) per second. Applying a force to an object causes it to accelerate.

WhakamĀrama Āpitihanga

Mā te tōpana a te tangata e whakatere ai te pahikara:

Mēnā ka ātete te tōpana i te ahunga o te mea e haere ana, ko te whakapōturi te hua. Ko tā te tōpana o te pereki, he ātete i te huri o te wīra:

E tātaihia ai te whakaterenga o tētahi mea, ka wehea te piki o te tere ki te wā e oti ai taua pikinga. Hei tauira: E tū ana tētahi waka i te tīmatanga, nō reira 0 mita/hākona tōna tere. I te paunga o te 5 hākona, e 20 mita/hākona tōna tere. Nō reira, hei tātai i te whakaterenga:

Ina tukuna tētahi mea kia taka i te hau takiwā, ko te tō ā-papa hei whakatere i taua mea. Ko te 10 mita i te hākona i ia hākona (10m/h²) te whakaterenga o te tangata e heke ana:

Koia nei te ture hei tātai i te tōpana whakatere i tētahi mea:

T = p × wh (T = tōpana, p = papatipu, wh = whakatere)

Nō reira, he nui ake te tōpana hei whakatere i tētahi mea he nui tōna papatipu, tērā i te tōpana hei whakatere i tētahi mea māmā:
