Isibonelo Sokunyakaza Okusheshayo Okuqondile (i-GLBB)
I-Uniformly Accelerated Linear Motion (GLBB) iyisihloko esibalulekile ku-physics esivame ukuvela ezifundweni zesikole samabanga aphezulu. I-GLBB ukunyakaza kwento emgqeni oqondile onokusheshisa okuqhubekayo. Kulesi sihloko, sizoxoxa ngencazelo, amafomula ayisisekelo, kanye nezibonelo eziningana zezinkinga ze-GLBB kanye nezixazululo zazo.
Incazelo Yokunyakaza Okusheshayo Okuqondile (i-GLBB)
I-Uniformly Accelerated Linear Motion (GLBB) ukunyakaza kwento elandela umugqa oqondile ngokusheshisa okuqhubekayo. Ukusheshisa okuqhubekayo kusho ukuthi izinga lokushintsha kwejubane lento lihlala lingaguquki ngokuhamba kwesikhathi. I-GLBB ingahlukaniswa ngezinhlobo ezimbili:
1. I-GLBB Esheshisiwe: Into ithola ukusheshisa okuhle (ukwanda kwesivinini).
2. I-GLBB Encishisiwe: Into ithola ukusheshisa okungekuhle (isivinini siyancipha).
Ifomula Eyisisekelo ye-GLBB
Amanye amafomula ayisisekelo ku-GLBB avame ukusetshenziswa yile:
1. Ifomula yesivinini sokugcina (v):
\[ v = v_0 + ku- \]
Di mana:
– \( v \) = ijubane lokugcina (m/s)
– \( v_0 \) = ijubane lokuqala (m/s)
– \( a \) = ukusheshisa (m/s²)
– \( t \) = isikhathi (izikhathi)
2. Ifomula yebanga:
\[ s = v_0 t + \frac{1}{2} at^2 \]
Di mana:
– \( s \) = ibanga elihanjiwe (m)
– \( v_0 \) = ijubane lokuqala (m/s)
– \( a \) = ukusheshisa (m/s²)
– \( t \) = isikhathi (izikhathi)
3. Ifomula yesivinini kanye nebanga elihanjiwe:
\[ v^2 = v_0^2 + 2 njengo \]
Di mana:
– \( v \) = ijubane lokugcina (m/s)
– \( v_0 \) = ijubane lokuqala (m/s)
– \( a \) = ukusheshisa (m/s²)
– \( s \) = ibanga elihanjiwe (m)
