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

contohnye...so klo bola tuh tinggi nape halajau die tinggi...nape mase die paling singkat tuk smpi ke bawah

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

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

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
