# Mehlala ea Lipotso tse Tšoanang tsa Motsamao o Molele
Motsamao o Tšoanang oa Linear (GLB) ke mohopolo oa motheo fisiks. Ke motsamao oa ntho tseleng e otlolohileng ka lebelo le sa fetoheng. Sena se bolela hore ha ho na ho potlaka, 'me lebelo le lula le tsitsitse hohle. Sengoloa sena se tla fana ka mehlala e 'maloa ea mathata a GLB le litharollo tsa ona ho u thusa ho utloisisa mohopolo ona hamolemo.
## Tlhaloso ea Motheo ea GLB
Pele re kena lipotsong tsa mohlala, ha re qaleng ka ho hlahloba likhopolo tse ling tsa motheo tsa Motsamao o Tšoanang oa Linear. Motsamaong o Tšoanang oa Linear, equation ea lebelo e hlalosoa e le:
\[ v = \frac{s}{t} \]
Moo:
– \( v \) ke lebelo,
– \( s \) ke sebaka,
– \(t \) ke nako.
Kaha lebelo ha le fetohe, sebaka seo motho a se tsamaileng se ka hlalosoa ka equation e otlolohileng:
\[ s = v \times t \]
ka:
– \( s \) ke sebaka seo motho a se tsamaileng,
– \( v \) ke lebelo le sa fetoheng,
– \(t \) ke nako e hlokahalang.
### Lipotso tsa Mehlala le Puisano
#### Potso ea 1: Ho Bala Sebaka
Potso:
Koloi e tsamaea ka lebelo le sa fetoheng la 60 km/h ka lihora tse 2. Koloi e tsamaea hole hakae?
Tharollo:
Ho sebelisoa foromo ea motheo ea sebaka ho GLB, \( s = v \times t \):
– Lebelo (\( v \)) = 60 km/h
– Nako (\( t \)) = dihora tse 2
Sebaka se tsamailweng (\( s \)):
\[ s = v \times t \]
\[ s = 60 \, \mongolo{km/hora} \makgetlo a 2 \, \mongolo{dihora} \]
\[s = 120 \, \mongolo{km} \]
Kahoo, sebaka se tsamauoang ke koloi ke 120 km.
#### Potso ea 2: Ho Bala Nako
Potso:
Motho ea tsamaeang ka maoto o tsamaea ka lebelo le sa fetoheng la 5 km/h. Haeba a tlameha ho tsamaea sebaka sa 15 km, ho tla nka nako e kae?
Tharollo:
Ho sebelisoa foromo ea motheo ea nako ho GLB, \( t = \frac{s}{v} \):
– Sebaka (\( s \)) = 15 km
– Lebelo (\( v \)) = 5 km/h
Nako e hlokahalang (\( t \)):
\[t = \frac{s}{v} \]
\[ t = \frac{15 \, \text{km}}{5 \, \text{km/h}} \]
\[t = 3 \, \text{jam} \]
Kahoo, nako e hlokahalang ho motho ea tsamaeang ka maoto ke lihora tse 3.
#### Potso ea 3: Ho Bala Lebelo
Potso:
Mopalami oa baesekele o tsamaea lik'hilomithara tse 18 ka lihora tse 1.5. Lebelo le sa fetoheng la mopalami oa baesekele ke lefe?
Tharollo:
Ho sebelisoa foromo ea motheo bakeng sa lebelo ho GLB, \( v = \frac{s}{t} \):
– Sebaka (\( s \)) = 18 km
– Nako (\( t \)) = dihora tse 1.5
Lebelo (\( v \)):
\[ v = \frac{s}{t} \]
\[ v = \frac{18 \, \text{km}}{1.5 \, \text{hora}} \]
\[v = 12 \, \mongolo{km/h} \]
Kahoo, lebelo le sa fetoheng la mopalami oa baesekele ke 12 km/h.
#### Potso ea 4: Motsoako oa Sebaka le Nako
Potso:
Terene e tsamaea lik'hilomithara tse 240 ka lebelo le sa fetoheng. Haeba ho nka lihora tse 3 ho koahela kotara ea pele ea sebaka seo, bala nako eohle e hlokahalang ho phethela leeto lohle.
Tharollo:
Sa pele, re bala sebaka sa kotara (1/4) ea leeto lohle:
\[ s_1 = \frac{1}{4} \makgetlo a 240 \, \mongolo{km} \]
\[ s_1 = 60 \, \mongolo{km} \]
Terene e nka 60 km ka dihora tse 3. Kahoo, lebelo la terene:
\[ v = \frac{60 \, \text{km}}{3 \, \text{hora}} \]
\[v = 20 \, \mongolo{km/h} \]
Ka mor'a moo, re bala nako eohle ea leeto la 240 km ka lebelo la 20 km/h:
\[t = \frac{s}{v} \]
\[ t = \frac{240 \, \text{km}}{20 \, \text{km/h}} \]
\[t = 12 \, \text{jam} \]
Kahoo, nako eohle e hlokahalang hore terene e koahele leeto lohle ke lihora tse 12.
#### Potso ea 5: Papiso ea Libaka ka Lintho tse peli
Potso:
Likoloi tse peli, A le B, li tsamaea ka lebelo le sa fetoheng la 60 km/h le 80 km/h ka ho latellana. Haeba li qala ho tsamaea ka nako e le 'ngoe ho tloha libakeng tse fapaneng, sebaka se pakeng tsa tsona ke sefe ka mor'a lihora tse 2?
Tharollo:
Koloi A:
\[ v_A = 60 \, \mongolo{km/h} \]
\[t = 2 \, \text{jam} \]
\[ s_A = v_A \makgetlo a t \]
\[ s_A = 60 \, \mongolo{km/hora} \makgetlo a 2 \, \mongolo{dihora} \]
\[ s_A = 120 \, \mongolo{km} \]
Koloi ea B:
\[ v_B = 80 \, \mongolo{km/h} \]
\[t = 2 \, \text{jam} \]
\[ s_B = v_B \makgetlo t \]
\[ s_B = 80 \, \mongolo{km/hora} \makgetlo a 2 \, \mongolo{dihora} \]
\[ s_B = 160 \, \mongolo{km} \]
Phapang pakeng tsa tse peli:
\[ \Delta s = s_B – s_A \]
\[ \Delta s = 160 \, \text{km} – 120 \, \text{km} \]
\[ \Delta s = 40 \, \mongolo{km} \]
Kahoo, kamora dihora tse 2, sebaka se pakeng tsa dikoloi tse pedi ke 40 km.
