Neʻe laina like

Ka wehewehe ʻana o ka neʻe laina like

ʻIke kahi mea i ka neʻe laina like inā paʻa ka wikiwiki o ka mea. Hoʻokomo pū ka wikiwiki i ka nui a me ke kuhikuhi o ka wikiwiki. Kuhikuhi o ka wikiwiki = kuhikuhi o ka neʻe ʻana = kuhikuhi o ka neʻe ʻana. ʻO ke kuhikuhi o ka wikiwiki o kahi mea paʻa = ke kuhikuhi o ka neʻe ʻana o kahi mea paʻa, a i ʻole ke kuhikuhi o ka neʻe ʻana o kahi mea paʻa = e neʻe pololei ana ka mea. ʻO ka nui o ka wikiwiki a i ʻole ka wikiwiki he paʻa = ua like mau ka wikiwiki i nā manawa a pau.

Inā he 10 m/s ka wikiwiki o ka mea, ʻoiai e neʻe ana ka mea, ʻo 10 m/s nō ka wikiwiki o ka mea. Inā neʻe kahi mea ma ka wikiwiki mau o 10 m/s, no ka laʻana, neʻe ka mea i 10 mika i kekona. I hoʻokahi kekona ma hope, neʻe ka mea i 10 mika mai kona kūlana mua ke hoʻomaka ka mea e neʻe ma ka wikiwiki mau o 10 m/s. ʻElua kekona ma hope, neʻe ka mea i 20 mika mai kona kūlana mua. ʻEkolu kekona ma hope, neʻe ka mea a hiki i 30 mika mai kona kūlana mua. A pēlā aku. Inā neʻe kahi mea ma ka wikiwiki mau o 20 m/s, no ka laʻana, neʻe ka mea i 20 mika i kekona. I hoʻokahi kekona ma hope, neʻe ka mea i 20 mika mai kona kūlana mua ke hoʻomaka ka mea e neʻe ma ka wikiwiki mau o 20 m/s. ʻElua kekona ma hope, neʻe ka mea i 40 mika mai kona kūlana mua. ʻEkolu kekona ma hope, neʻe ka mea a hiki i 60 mika mai kona kūlana mua. A pēlā aku.

ʻO ka neʻe laina like ʻole ka neʻe ʻana me ka wikiwiki mau (ʻo ka nui a me ke kuhikuhi o ka wikiwiki he mau) no laila ʻaʻohe wikiwiki. Pono e hoʻomaopopo ʻia ʻo ka neʻe laina like e hana ʻia ma ka ʻili o ka honua e hana wale ʻia ma ke kuhikuhi pae.

ʻO ke kaulike o ka neʻe laina like

Hoʻākāka nā kaulike a i ʻole nā ​​haʻilula i ka neʻe laina like i ka pilina ma waena o nā nui kino i ka neʻe laina like. Aia kekahi mau nui kino i ka neʻe laina like, me ka manawa manawa (t), ka mamao (d), a me ka wikiwiki (v). ʻO ka pilina ma waena o kēia mau nui kino ʻekolu i hōʻike ʻia ma o ka kaulike:

v = d / t

v = ka wikiwiki (ʻāpana SI o ka wikiwiki ma nā mika i kekona, i hoʻopōkole ʻia m/s)

d = mamao (ʻo ke anakahi SI o ka mamao he mika, i hoʻopōkole ʻia ʻo m)

t = manawa (ʻo ke anakahi SI o ka manawa he kekona, i hoʻopōkole ʻia he s)

Laʻana pilikia 1 (me ka ʻole o ke ʻano):

Neʻe pololei kekahi ʻāpana i ka wikiwiki mau o 10 m/s.

a) He aha ka wikiwiki o ka ʻāpana ma hope o ka neʻe ʻana no 2 kekona?

b) He aha ka mamao ma hope o ka neʻe ʻana no 5 kekona?

pāʻoihana:

a) Ka wikiwiki mau = 10 m/s.

b) ʻO 10 m/s ke ʻano he 10 mika no 1 kekona. 50 mika ma hope o 5 kekona.

Laʻana pilikia 2 (me ka ʻole o ke ʻano):

Neʻe kekahi kaʻa me ka wikiwiki mau o 60 km/h. He aha ka mamao ma hope o ka neʻe ʻana no 10 mau minuke?

pāʻoihana:

60 km / h = 60 km / 60 minuke = 1 km / minuke = 10 km / 10 minuke.

Nā nīnau manaʻo a me nā pane e pili ana i ka neʻe laina like

1. He aha ka neʻe laina like?

   ʻO ka neʻe laina like ka neʻe ʻana ma kahi laina pololei ma ka wikiwiki mau a i ʻole ka velocity mau.

2. He aha ke ʻano hana no ka neʻe laina like?

   K? Ne? Ia? Ana s = vt, kahi ʻo s ka neʻe ʻana a i ʻole ka mamao, ʻo v ka wikiwiki, a ʻo t ka manawa i lawe ʻia.

3. Hiki ke ʻōlelo ʻia ke kino e hoʻomaha ana he neʻe laina like?

   ʻAe, hiki ke manaʻo ʻia ke kino e hoʻomaha ana ma ke ʻano he neʻe laina like me ka wikiwiki o ka ʻole.

4. He aha ka mea e hōʻike ai ka piʻo o kahi pakuhi mamao-manawa i ka neʻe laina like?

   Hōʻike ka piʻo o kahi pakuhi mamao-manawa i ka neʻe laina like i ka wikiwiki a i ʻole ka wikiwiki o ka mea.

5. Hiki i kahi mea ma ka neʻe laina like ke loaʻa ka wikiwiki?

   ʻAʻole, ʻaʻole hiki i kahi mea ma ka neʻe laina like ke loaʻa ka wikiwiki no ka mea he mau kona wikiwiki.

6. He aha ke anakahi o ka wikiwiki i loko o ka International System of Units (SI)?

   I ka neʻe laina like, inā pālua ka manawa 't', e pālua pū ka neʻe ʻana o 's', no ka mea, ua like pololei ka neʻe ʻana me ka manawa.

10. He aha ka mea e hana ʻia i ka neʻe ʻana o ka 's' i ka neʻe laina like ke lilo ka wikiwiki 'v' i ʻole?

Ke lilo ka wikiwiki 'v' i ʻole, lilo pū ka neʻe ʻana 's' i ʻole. Pili kēia i kahi mea e hoʻomaha ana.

11. Pehea ka ʻokoʻa o ka neʻe laina like mai ka neʻe wikiwiki like?

I ka neʻe laina like, paʻa ka wikiwiki, akā i ka neʻe wikiwiki like, loli ka wikiwiki ma kahi wikiwiki mau.

12. Pehea ka hopena o ka hoʻololi ʻana i ka wikiwiki i ka neʻe laina like o kahi mea?

ʻOiai ʻo ka neʻe laina like ke ʻano o ka wikiwiki mau, ʻo kēlā me kēia loli o ka wikiwiki ʻo ia hoʻi ʻaʻole like a linear hou ka neʻe ʻana.

13. Hiki i ka neʻe ʻana o 's' ke maikaʻi ʻole i ka neʻe laina like?

ʻAe, hiki i ka neʻe ʻana o nā 's' ke lilo i mea maikaʻi ʻole i ka neʻe laina like. E hōʻike ana kēia i ka neʻe ʻana i ke kuhikuhi ʻē aʻe i ke kuhikuhi maikaʻi i koho ʻia.

14. Pehea e hiki ai i kekahi ke ʻike i ka neʻe laina like i loko o kahi pakuhi wikiwiki-manawa?

Hōʻike ʻia ka neʻe laina like e kahi laina ʻapapa i loko o kahi pakuhi wikiwiki-manawa, e hōʻike ana he mau ka wikiwiki i ka hala ʻana o ka manawa.

15. He aha ke kuleana o nā ikaika i ka neʻe laina like?

Inā ʻaʻohe ikaika ʻupena e hana ma luna o kahi mea (a inā kaulike nā ikaika āpau), hiki i ka mea ke hoʻomau i ka neʻe ʻana me ka wikiwiki mau, ʻo ia hoʻi, ma ka neʻe laina like. Ua kūlike kēia me ke kānāwai mua o ka neʻe ʻana o Newton.

16. Pehea e ana ʻia ai ka manawa 't' i ka neʻe laina like?

ʻO ka maʻamau, ana ʻia ka manawa 't' mai ka hoʻomaka ʻana o ka neʻe ʻana i ʻike ʻia a hiki i ka hopena o ka neʻe ʻana i ʻike ʻia.

ʻAʻole e kū kahi mea e neʻe ana ma ke ʻano laina like ke ʻole e hana ʻia e kahi ikaika o waho. Hoʻokumu ʻia kēia ma ke kānāwai mua o ka neʻe ʻana o Newton.

18. He aha ke ʻano o ka neʻe laina like ʻana o kahi mea ma ka lewa?

Neʻe kahi mea ma ka neʻe laina like ma ka lewa ma kahi wikiwiki mau ma kahi laina pololei, a e hoʻomau ia i ka hana pēlā ke ʻole e hana ʻia e kahi ikaika o waho.

19. Hiki i nā mea ʻelua ke neʻe laina like kekahi i kekahi?

ʻAe, inā e neʻe ana nā mea ʻelua ma ke kuhikuhi like ma ka wikiwiki mau like, aia lākou i ka neʻe laina like kekahi i kekahi.

20. Hiki iā kākou ke hoʻopili i ke ʻano hana no ka neʻe laina like (s = vt) i kahi mea e neʻe ana ma ke ala pōʻai ma ka wikiwiki mau?

ʻAʻole, ʻaʻole hiki iā mākou. ʻOiai paha e mau ana ka wikiwiki no kahi mea e neʻe ana ma ke ala pōʻai, ʻaʻole mau ka wikiwiki no ka mea e loli mau ana kona kuhikuhi. Pili pono ke ʻano s = vt i ka neʻe laina like.
