# Izibonelo Zemibuzo Yokunyakaza Okulinganayo Okuqondile
I-Uniform Linear Motion (GLB) ingumqondo oyisisekelo ku-physics. Ukunyakaza kwento endleleni eqondile ngesivinini esingaguquki. Lokhu kusho ukuthi akukho ukusheshisa, futhi ijubane lihlala lingaguquki kuyo yonke indawo. Lesi sihloko sizonikeza izibonelo eziningana zezinkinga ze-GLB kanye nezixazululo zazo ukukusiza ukuthi uqonde kangcono lo mqondo.
## Incazelo Eyisisekelo ye-GLB
Ngaphambi kokuba singene emibuzweni eyisibonelo, ake siqale sibukeze imiqondo eyisisekelo ye-Uniform Linear Motion. Ku-Uniform Linear Motion, i-velocity equation ichazwa kanje:
\[ v = \frac{s}{t} \]
Kuphi:
– \( v \) ijubane,
– \( s \) ibanga,
– \(t \) yisikhathi.
Njengoba ijubane lingaguquguquki, ibanga elihanjiwe lingachazwa ngesibalo esiqondile:
\[ s = v \izikhathi t \]
no:
– \( s \) ibanga elihanjiwe,
– \( v \) ijubane elingaguquki,
– \(t \) yisikhathi esidingekayo.
### Imibuzo Yesibonelo Nengxoxo
#### Umbuzo 1: Ukubala Ibanga
Umbuzo:
Imoto ihamba ngesivinini esingaguquki samakhilomitha angu-60 ngehora amahora amabili. Ihamba ibanga elingakanani imoto?
Isixazululo:
Ukusebenzisa ifomula yebanga eliyisisekelo ku-GLB, \( s = v \times t \):
– Isivinini (\( v \)) = 60 km/h
– Isikhathi (\( t \)) = amahora ama-2
Ibanga elihanjiwe (\( s \)):
\[ s = v \izikhathi t \]
\[ s = 60 \, \umbhalo{km/ihora} \izikhathi 2 \, \umbhalo{amahora} \]
\[ s = 120 \, \umbhalo{km} \]
Ngakho-ke, ibanga elihanjwa yimoto liyi-120 km.
#### Umbuzo 2: Ukubala Isikhathi
Umbuzo:
Umuntu ohamba ngezinyawo uhamba ngesivinini esingaguquki esingu-5 km/h. Uma kufanele ahambe ibanga elingamakhilomitha ayi-15, kuzothatha isikhathi esingakanani?
Isixazululo:
Ukusebenzisa ifomula eyisisekelo yesikhathi ku-GLB, \( t = \frac{s}{v} \):
– Ibanga (\( s \)) = 15 km
– Isivinini (\( v \)) = 5 km/h
Isikhathi esidingekayo (\( t \)):
\[ t = \frac{s}{v} \]
\[ t = \frac{15 \, \text{km}}{5 \, \text{km/h}} \]
\[t = 3 \, \text{jam} \]
Ngakho-ke, isikhathi esidingwa umuntu ohamba ngezinyawo singamahora amathathu.
#### Umbuzo 3: Ukubala Isivinini
Umbuzo:
Umgibeli webhayisikili uhamba amakhilomitha ayi-18 ngamahora angu-1.5. Ingakanani ijubane elingaguquki lomgibeli webhayisikili?
Isixazululo:
Ukusebenzisa ifomula eyisisekelo yejubane ku-GLB, \( v = \frac{s}{t} \):
– Ibanga (\( s \)) = 18 km
– Isikhathi (\( t \)) = amahora ama-1.5
Ijubane (\( v \)):
\[ v = \frac{s}{t} \]
\[ v = \frac{18 \, \text{km}}{1.5 \, \text{hour}} \]
\[ v = 12 \, \umbhalo{km/h} \]
Ngakho-ke, ijubane elingaguquki lomgibeli webhayisikili lingu-12 km/h.
#### Umbuzo 4: Inhlanganisela Yebanga Nesikhathi
Umbuzo:
Isitimela sihamba amakhilomitha angu-240 ngesivinini esingaguquki. Uma kuthatha amahora amathathu ukumboza ikota yokuqala yebanga, bala isikhathi esiphelele esidingekayo ukuqedela lonke uhambo.
Isixazululo:
Okokuqala, sibala ibanga lekota (1/4) yohambo lonke:
\[ s_1 = \frac{1}{4} \izikhathi ezingu-240 \, \umbhalo{km} \]
\[ s_1 = 60 \, \umbhalo{km} \]
Isitimela sihamba amakhilomitha angu-60 ngamahora amathathu. Ngakho-ke, isivinini sesitimela:
\[ v = \frac{60 \, \text{km}}{3 \, \text{hour}} \]
\[ v = 20 \, \umbhalo{km/h} \]
Okulandelayo, sibala isikhathi esiphelele sohambo lwamakhilomitha angu-240 ngesivinini samakhilomitha angu-20 ngehora:
\[ t = \frac{s}{v} \]
\[ t = \frac{240 \, \text{km}}{20 \, \text{km/h}} \]
\[t = 12 \, \text{jam} \]
Ngakho-ke, isikhathi esiphelele esidingekayo ukuze isitimela sihlanganise lonke uhambo singamahora ayi-12.
#### Umbuzo 5: Ukuqhathanisa Amabanga Ngezinto Ezimbili
Umbuzo:
Izimoto ezimbili, u-A no-B, zihamba ngesivinini esingaguquki esingu-60 km/h kanye no-80 km/h ngokulandelana. Uma ziqala ukuhamba ngesikhathi esifanayo zivela ezindaweni ezahlukene, ibanga elingakanani phakathi kwazo ngemva kwamahora amabili?
Isixazululo:
Imoto A:
\[ v_A = 60 \, \umbhalo{km/h} \]
\[t = 2 \, \text{jam} \]
\[ s_A = v_A \izikhathi t \]
\[ s_A = 60 \, \umbhalo{km/ihora} \izikhathi 2 \, \umbhalo{amahora} \]
\[ s_A = 120 \, \umbhalo{km} \]
Imoto B:
\[ v_B = 80 \, \umbhalo{km/h} \]
\[t = 2 \, \text{jam} \]
\[ s_B = v_B \izikhathi t \]
\[ s_B = 80 \, \umbhalo{km/ihora} \izikhathi 2 \, \umbhalo{amahora} \]
\[ s_B = 160 \, \umbhalo{km} \]
Umehluko ngebanga phakathi kwalokhu okubili:
\[ \Delta s = s_B – s_A \]
\[ \Delta s = 160 \, \text{km} – 120 \, \text{km} \]
\[ \Delta s = 40 \, \umbhalo{km} \]
Ngakho-ke, ngemva kwamahora amabili, ibanga phakathi kwezimoto ezimbili lingu-40 km.
