Kaitirotiro pūngao kinetic
Ka whakaoti KE = ½mv² mō te pūngao, te nui, te tere rānei, me te āwhina me te ānau.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
the calculator, the kinetic energy is the energy an object has because it is moving, KE = ½ × 2 × 3² = 9 joules and momentum p = 2 × 3 × 3² = 6 kg·m/s. Speed it up to 6 m/s and the kinetic energy jumps to ½ × 2 × 3 = 6 kg·m/s. Solving in reverse, 9 J in a 2 kg mass implies a speed of √(2 × 9 / 2)The squared-speed relationshipThe squared-speed relationship explains a lot of the real world: why stopping distances grow so sharply with speed and momentum p = 2 × 3 × 3² = 9 joules and momentum p = 2 × 3 × 3² = 6 kg·m/s.The squared-speed relationship explains a lot of the real world:
Ko nga pātai e pā ana
He aha te tātai pūngao kinetic?
Ko te pūngao kinetic KE = ½ × m × v2, kei reira te m te taumahatanga i roto i ngā pakiaka me te v te tere i roto i ngā mita i ia wa. He 2 kg te ahanoa i te 3 m/s, he ½ × 2 × 9 = 9 ngā joule.
He aha te nui ake o te tere i te tini?
Ka whakatōpūtia te pūngao pūngao ki te tapawhā o te tere, engari he paerangi anake me te tini, kia rua te tere e whakarea ana i te pūngao e whā, ā, ko te whakaruatanga o te tini e rua anake.
He aha te rerekētanga i waenganui i te pūngao kinetic me te pūngao?
Ko te pūngao p = m × v me te tauine paerangi me te tere, i te wā e ½ m te pūngao kinetic v² me te tauine me te tere tapawhā. He 2 kg te taumaha i te 3 m/s he 6 kg m/s te tere, engari he 9 J te pūngao; i te tere rua ka rua te tere, engari ka whā te pūngao.
He pēhea te kimi i te tere mai i tētahi pūngao pūkaha e mōhiotia ana?
Ka whakahōu anō ki te v = √(2·KE/m). Ka whakatū "whakataua" ki te tere, ka tāuru te pūngao me te taumaha, ā, ka mahi te tātaitai — hei tauira, 9 J i roto i te taumaha o te 2 kg e tuku ana i te √(18/2) = 3 m/s.
He aha te tere o te tere o te tere?
Ko te whakarerekētanga e tango ana i te pūngao kinetic i tētahi mokatere tata tonu, ā, ka nui ake taua pūngao me te tapawhā o te tere. Ko te whakaruatanga o tō tātau tere e whakawhāiti ana i te pūngao e tukua ana, nō reira ka tata tonu te whakawhāiti i te tawhiti o te whakarerekētanga.
He aha nga wae me whakamahia e au?
Ka whakamahia ngā wae SI — te nui i roto i ngā kiloko me te tere i roto i ngā mita i ia wa — hei whiwhi pūngao i roto i ngā joule. Mēnā kei a koe te km/h, ka wehea e te 3.6 hei tahuri ki m/s i mua i te tāurunga.
