Imibuzo emi-3 mayelana ne-Angular velocity equation
1. Into ehamba endleleni eyindilinga inobubanzi obungu-0.5 m. Le nhlayiya iyakwazi ukumboza i-engeli engu-60π rad ngemizuzwana eyi-15. Thola ijubane le-engeli lento.
Kwaziwa:
Irediyasi (r) = amamitha angu-0.5
I-engeli (θ) = 60π rad
Isikhawu sesikhathi (t) = imizuzwana eyi-15
Okufunwayo: Ijubane le-angular (ω)
Isixazululo:
θ = ω t
60π = ω (15)
ω = 60π / 15 = 4π rad/s
2. Isondo lebhayisikili elinobubanzi obungamasentimitha angu-30 lijikeleza ngesivinini esingaguquki. Ivalvu yesondo ingajikeleza nge-engeli engu-120π rad imizuzwana eyi-10. Thola isivinini se-angular.
Kwaziwa:
Irediyasi (r) = 30 cm
I-engeli (θ) = 120π rad
Isikhawu sesikhathi (t) = 10 s
Okufunwayo: Ijubane le-angular (ω)
Isixazululo:
θ = ω t
120π = ω (10)
ω = 120π / 10 = 12π rad/s
3. Intambo igoqwe isondo elinerediyasi R = 25 cm njengoba kuboniswe. Uma iphuzu entanjeni (iphuzu A) linesivinini esingu-5 m/s khona-ke ijubane lokujikeleza kwesondo…
Kwaziwa:
Irediyasi (r) = 25 cm = 0.25 amamitha
Isivinini (v) = 5 m/s
Okufunwayo: Ijubane le-angular (ω)
Isixazululo:
Ifomula yobudlelwano phakathi kwejubane le-angular, ijubane eliqondile kanye ne-radius:
v = r ω
5 = (0,25) ω
ω = 5 / 0,25 = 20 rad/s
