# Mienzaniso yeMibvunzo yeKufamba Kwemutsetse Yakafanana
Uniform Linear Motion (GLB) ipfungwa huru mufizikisi. Inzira yekufamba kwechinhu munzira yakatwasuka nekumhanya kwakasimba. Izvi zvinoreva kuti hapana kukurumidza, uye kumhanya kwacho kunoramba kuripo kwese. Chinyorwa chino chichapa mienzaniso yakati wandei yezvinetso zveGLB nemhinduro dzazvo kuti zvikubatsire kunzwisisa pfungwa iyi zviri nani.
## Tsananguro Yekutanga yeGLB
Tisati tapinda mumibvunzo yemuenzaniso, ngatitangei taongorora dzimwe pfungwa dzekutanga dzeUniform Linear Motion. MuUniform Linear Motion, velocity equation inotsanangurwa se:
\[ v = \frac{s}{t} \]
dimana:
– \( v \) ndiyo kumhanya,
– \( s \) ndiko kureba,
– \(t \) inguva.
Sezvo kumhanya kwacho kuri kusingagumi, daro rinofambwa rinogona kutsanangurwa ne equation yakatsetseka:
\[ s = v \nguva t \]
ne:
– \( s \) idaro rakafambwa,
– \( v \) inguva isingachinji,
– \(t \) ndiyo nguva inodiwa.
### Mibvunzo yeMienzaniso neKukurukurirana
#### Mubvunzo 1: Kuverenga Kureba
Mubvunzo:
Mota inofamba nekumhanya kwakafanana kwe60 km/awa kwemaawa maviri. Mota yacho inofamba kure zvakadii?
Mhinduro:
Uchishandisa fomura yekutanga yedaro muGLB, \( s = v \times t \):
– Kumhanya (\( v \)) = 60 km/h
– Nguva (\( t \)) = maawa maviri
Kureba kwakaitwa (\( s \)):
\[ s = v \nguva t \]
\[ s = 60 \, \text{km/awa} \times 2 \, \text{hours} \]
\[ s = 120 \, \mashoko{km} \]
Saka, daro rinofambwa nemota iri makiromita zana nemakumi maviri.
#### Mubvunzo 2: Kuverenga Nguva
Mubvunzo:
Munhu anofamba netsoka anofamba nekumhanya kwakafanana kwe5 km/awa. Kana achifanira kufamba daro re15 km, zvinotora nguva yakareba sei?
Mhinduro:
Uchishandisa fomura yekutanga yenguva muGLB, \( t = \frac{s}{v} \):
– Kureba (\( s \)) = 15 km
– Kumhanya (\( v \)) = 5 km/h
Nguva inodiwa (\( t \)):
\[ t = \frac{s}{v} \]
\[ t = \frac{15 \, \text{km}}{5 \, \text{km/h}} \]
\[t = 3 \, \text{jam} \]
Saka, nguva inodiwa nemunhu anofamba netsoka maawa matatu.
#### Mubvunzo 3: Kuverenga Kumhanya
Mubvunzo:
Munhu anotasva bhasikoro anofamba makiromita gumi nemasere muawa imwe nehafu. Kumhanya kwakasimba kwemunhu anotasva bhasikoro kwakadini?
Mhinduro:
Uchishandisa fomura yekutanga yekukurumidza muGLB, \( v = \frac{s}{t} \):
– Kureba (\( s \)) = 18 km
– Nguva (\( t \)) = maawa maviri
Kumhanya (\( v \)):
\[ v = \frac{s}{t} \]
\[ v = \frac{18 \, \text{km}}{1.5 \, \text{hour}} \]
\[ v = 12 \, \mashoko{km/h} \]
Saka, kumhanya kunogara kuripo kwemutyairi webhasikoro i12 km/awa.
#### Mubvunzo 4: Musanganiswa wedaro nenguva
Mubvunzo:
Chitima chinofamba makiromita mazana maviri nemakumi mana (240 km) nekumhanya kwakafanana. Kana zvichitora maawa matatu kuti chifukidze chikamu chekutanga chedaro, verenga nguva yose inodiwa kuti rwendo rwese rupere.
Mhinduro:
Kutanga, tinoverenga daro rechikamu chimwe muzvina (1/4) cherwendo rwose:
\[ s_1 = \frac{1}{4} \kawa 240 \, \text{km} \]
\[ s_1 = 60 \, \mashoko{km} \]
Chitima chinofamba makiromita makumi matanhatu (60 km) mumaawa matatu. Saka, kumhanya kwechitima:
\[ v = \frac{60 \, \text{km}}{3 \, \text{hour}} \]
\[ v = 20 \, \mashoko{km/h} \]
Tevere, tinoverenga nguva yose yerwendo rwemakiromita mazana maviri nemakumi mana nekumhanya kwemakiromita makumi maviri paawa:
\[ t = \frac{s}{v} \]
\[ t = \frac{240 \, \text{km}}{20 \, \text{km/h}} \]
\[t = 12 \, \text{jam} \]
Saka, nguva yose inodiwa kuti chitima chifukidze rwendo rwese i12 maawa.
#### Mubvunzo 5: Kuenzanisa Madaro neZvinhu Zviviri
Mubvunzo:
Mota mbiri, A neB, dziri kufamba nekumhanya kwakafanana kwe60 km/h uye 80 km/h zvakateerana. Kana dzikatanga kufamba panguva imwe chete dzichibva panzvimbo dzakasiyana, daro riri pakati padzo nderei mushure memaawa maviri?
Mhinduro:
Mota A:
\[ v_A = 60 \, \mashoko{km/h} \]
\[t = 2 \, \text{jam} \]
\[ s_A = v_A \nguva t \]
\[ s_A = 60 \, \mashoko{km/awa} \nguva 2 \, \mashoko{maawa} \]
\[ s_A = 120 \, \mashoko{km} \]
Mota B:
\[ v_B = 80 \, \mashoko{km/h} \]
\[t = 2 \, \text{jam} \]
\[ s_B = v_B \nguva t \]
\[ s_B = 80 \, \mashoko{km/awa} \nguva 2 \, \mashoko{maawa} \]
\[ s_B = 160 \, \mashoko{km} \]
Musiyano uripo pakati pezviviri izvi:
\[ \Delta s = s_B – s_A \]
\[ \Delta s = 160 \, \text{km} – 120 \, \text{km} \]
\[ \Delta s = 40 \, \text{km} \]
Saka, mushure memaawa maviri, chinhambwe chiri pakati pemotokari mbiri idzi chinosvika makiromita makumi mana.
### Mhedziso
Kufamba Kwemutsetse Uniform Linear ipfungwa huru mufizikisi inotsanangura kufamba nekumhanya kunogara kuripo. Kuburikidza nemienzaniso yakapihwa, vaverengi vanotarisirwa kunzwisisa zviri nani mashandisirwo emhando yekufamba kwemutsetse uniform linear mumamiriro akasiyana-siyana. Matambudziko aya haangobatsiri chete kunzwisisa dzidziso asiwo mashandisirwo anoshanda muhupenyu hwezuva nezuva. Kuti unzwisise kufamba kwemutsetse uniform linear, zvinokurudzirwa kuti urambe uchidzidzira nematambudziko akasiyana-siyana.
