Dhibaatooyinka lagu xalliyay Dhaqdhaqaaqa Toosan - walxaha si xor ah u dhacaya
1. Shay ka soo dhacay dusha sare ee buur. Waxaa la arkayaa inuu dhulka ku dhacayo 3 ilbiriqsi ka dib. Go'aami xawaaraha uu ku socdo wax yar ka hor inta uusan dhulka ku dhicin. Dardargelinta cufisjiidadka waa 10 m/s 2. Iska ilow iska caabbinta biyaha.
La yaqaan:
Xawaaraha bilowga ah (vo o ) = 0 (shay la tuuray)
Muddada (t) = 3 ilbiriqsi
Dardargelinta cufisjiidadka (g) = 10 m/s 2
La Doonayo: Xawaaraha kama dambaysta ah (v t )
Xalka:
Dardargelinta cufisjiidadka dhulka dushiisa, baaxaddiisu waa 9.8 m/s 2. Si aan u fududeyno xisaabinta, waxaan isticmaalnaa 10 m/s 2.
10 m/s 2 ama 10 m/s / 1 ilbiriqsi, macnaheedu waa in xawaaruhu si toosan u kordho waqtiga 10 m/s ilbiriqsi kasta.
Ka dib 1 ilbiriqsi, xawaaraha shayga = 10 m/s
2 ilbiriqsi ka dib, xawaaraha shayga = 20 m/s
3 ilbiriqsi ka dib, xawaaraha shayga = 30 m/s.
Waxaan sidoo kale u isticmaali karnaa isla'egyada kinematic-ka dhaqdhaqaaqa xawaare joogto ah , sida hoos ku cad.
v t = v o + at
s = v o t + ½ marka la gaaro 2
v t 2 = v o 2 + 2 sida
Hoos u dhaca xorta ah ma laha xawaare bilow ah (v o = 0), markaa isla'egta kor ku xusan waa la bedeli karaa sida hoos ku cad:
Isle'egta dhaqdhaqaaqa xorta ah ee dhacaya :
v t = gt ………… 1
h = ½ gt 2 ………… 2
v t 2 = 2 gh ………….. 3
v t = gt
v t = (10)(3)
v t = 30 m/s
Xawaaraha kama dambaysta ah waa 30 m/s
2. Jidhku si xor ah ayuu uga dhacaa nasashada, isagoo ka soo dhacaya dherer dhan 25 m. Soo hel (a) Xawaaraha uu dhulka ku dhufto. (b) Waqtiga ay qaadato in dhulka la gaaro.
Xawaaraha ay sabab u tahay cufisjiidadka dhulka dushiisa waa 10 m/s 2.
La yaqaan:
Dhererka (h) = 5 mitir
Dardargelinta cufisjiidadka (g) = 10 m/s 2
La doonayo:
(a) Xawaaraha kama dambaysta ah (v t )
(b) Muddada (t)
Xalka:
Isle'egta dayrta xorta ah:
v t = gt
h = ½ gt 2
v t 2 = 2 gh
(a) Xawaaraha kama dambaysta ah (v t )
v t 2 = 2 gh = 2(10)(5) = 100
v t = 10 m/s
(b) Muddada (t)
h = ½ gt 2
5 = ½ (10) t 2
5 = 5 t 2
t 2 = 5/5 = 1
t = 1 ilbiriqsi
3. Kubad ayaa ka soo dhacday meel sare. Soo hel (a) Dardargelin (b) Masaafada ka dib 3 ilbiriqsi (c) Waqtiga hawada ku jira haddii xawaaraha kama dambaysta ahi yahay 20 m/s. Dardargelinta ay sabab u tahay cufisjiidadka = 10 m/s 2
La yaqaan :
Dardargelinta cufisjiidadka (g) = 10 m/s 2
La doonayo:
(a) Dardargelinta (a)
(b) Masaafada ama dhererka (h) haddii waqtigu dhaafay (t) = 3 ilbiriqsi
(c) Muddada waqtiga (t) haddii v t = 20 m/s
Xalka:
Isle'egta dayrta xorta ah:
v t = gt
h = ½ gt 2
v t 2 = 2 gh
(a) Dardargelinta (a)
Dardargelinta = dardargelinta cufisjiidadka awgeed = 10 m/s 2. Waxay la macno tahay kororka xawaaraha 10 m/s ilbiriqsikiiba.
(b) Masaafada ama dhererka (h) ka dib t = 3 ilbiriqsi
h = ½ gt 2 = ½ (10)(3) 2 = (5)(9) = 45 mitir
(c) Waqtiga dhaafay (t) haddii v t = 20 m/s
v t = gt
20 = (10) t
t = 20 / 10 = 2 ilbiriqsi
