hubungan antara ketinggian n halaju
[Copy link]

ape ek...nape pada an inclined plane...makin tinggi halaju pon makin tmbh...aku tak paham... |
|

tolong haku sblm 4.30 nih |

i tak faham soalan you actually and ni sure pasal bab dynamic and mechanics...well....soalan you i tak faham...
what are you trying to ask?
sapa nak tolong dia?
semakin tinggi , semakin tambah halaju dalam inclined plane?
it is inclined anyway so logically you would think that the speed? momentum .....i have no idea hehehe

sbbnye tah nape aku pikir logik v=d/t |
|
|
|

v tinggi d pon tinggi....lahai..aku da mengong da nih |

yes...huhuh kelas kol 5 kang..any idea |

ini disebabkan oleh tarikan graviti...pecutan graviti, g=9.81m/s yg menyebabkan halaju bola bertambah mengikut ketinggian....just follow this equation...ni hbgnnye
1/2at^(2) + ut = d
dimana d= ketinggian objek dr tanah, a=pecutan graviti, u=halaju awal(maksudnya halaju bola ktk tibe atas tanah)
masuk je nilai dalam persamaan ni, so selesailah masalah |
|
|
|
|
|
|
|
tambah sikit...this equation true bile :
1) no internal force
2)halaju akhir(halaju bile jatuhkan bola)=0 |
|
|
|
|
|
|
|
ktk tu ape...so kesimpulannye...d atau s tuh tinggi....maka u pon tinggila...leh tak aku cakap camtu |
|
|
|
|
|
|
|
ehh sat...lahai aku tak bawak data la..... |
|
|
|
|
|
|
|
eh ....bukan u =0 ker halaju awai...pecutan lak malar kan...so persamaan tuh nk cakap aper ek... |

pasal incline plane...pun same
cume kat sini memerlukan newton' second law & third law...nk explain susah skt
sbb melibatkan sudut ketinggian & so daya disebabkan graviti menyebabkan bola jatuh kebawah |

lahai camne ek..berharap jelah...derang tak prasan |

ok tq.......ape2 pon...lambat sangat aku taye..baru terpk tak sat nihOriginally posted by dauswq at 3-3-2009 04:35 PM

jsut bear with the concept I stated above....incline plane mcm free fall jgk
so jgn confuse ok
halaju awal kat sini bknnye halaju bile nk jatuhkan bola tp halaju bile tibe tanah |

konfius la plak..halaju awai bile tibe tanah......emmmmm...Originally posted by dauswq at 3-3-2009 04:37 PM

emm kne balik dulu la...k la tq...hope everything goes well...arituh....depe dok tye lecturer fizik....tecer...aritu teacher ajar salah...yang persamaan tuh tayah masukkan negatif...terus aku cuak |
