Motsamao o lekanang o otlolohileng, o tsejoang hape e le motsamao o lekanang o otlolohileng, o bolela motsamao oa ntho ka lebelo le sa fetoheng tseleng e otlolohileng. Mofuta ona oa motsamao o khetholloa ka lebelo le sa fetoheng, ho bolelang hore ha ho na ho potlaka. Mafapheng a fapaneng a kang fisiks, boenjiniere le bophelo ba letsatsi le letsatsi, mehlala ea motsamao o lekanang o otlolohileng e mengata. Sengoloa sena se hlahloba mathata a mangata a bophelo ba sebele le a khopolo-taba a bontšang motsamao o lekanang o otlolohileng, o fanang ka litlhaloso le litharollo ho ntlafatsa kutloisiso.
## Melao-motheo ea Motheo ea Motsamao o Tšoanang oa Moeli o Lehlakoreng
Pele o teba mehlaleng, ho bohlokoa ho utloisisa melao-motheo ea motheo e laolang motsamao o ts'oanang oa mola. Tekanyo ea motheo e hlalosang motsamao ona ke:
\[d = vt \]
moo:
– \( d \) ke sebaka se tsamailweng,
– \( v \) ke lebelo le sa fetoheng,
– \(t \) ke nako e fetileng.
Tekanyo ena e senola hore bakeng sa ntho e tsamaeang ka tsela e ts'oanang, sebaka se koahetsoeng se lekana ka ho toba le nako e nkiloeng.
## Mathata a Mohlala
### Mohlala oa 1: Terene e Tsamaeang
Bothata: Terene e tsamaea tseleng e otlolohileng ka lebelo le sa fetoheng la 90 km/h. E tla be e tsamaile sebaka se sekae ka mora dihora tse 2.5?
tharollo:
Ho sebelisoa equation \( d = vt \):
\[
d = 90 \, \mongolo{km/h} \makgetlo a 2.5 \, \mongolo{h} = 225 \, \mongolo{km}
\]
Ka hona, terene e tla nka sebaka sa lik'hilomithara tse 225 ka lihora tse 2.5.
### Mohlala oa 2: Motho ea tsamaeang ka maoto
Bothata: Motho ea tsamaeang ka maoto o tsamaea ka lebelo le tsitsitseng la 5 km/h. Bala sebaka seo motho ea tsamaeang ka maoto a se tsamaeang ka lihora tse 3.
tharollo:
Ho sebelisoa equation \( d = vt \):
\[
d = 5 \, \mongolo{km/h} \makgetlo a 3 \, \mongolo{h} = 15 \, \mongolo{km}
\]
Ka hona, motho ea tsamaeang ka maoto o tla tsamaea lik'hilomithara tse 15 ka lihora tse 3.
### Mohlala oa 3: Thomello ea Express
Bothata: Sephutheloana se a isoa 'me se tsamaisoa ka lebelo le sa fetoheng la 60 km/h nako ea lihora tse 4. Fumana sebaka sohle se tsamailoeng ke sephutheloana.
tharollo:
Ho sebelisoa equation \( d = vt \):
\[
d = 60 \, \mongolo{km/h} \makgetlo a 4 \, \mongolo{h} = 240 \, \mongolo{km}
\]
Kahoo, sephutheloana se tla be se tsamaile dikhilomithara tse 240 kamora dihora tse 4.
### Mohlala oa 4: Sefofane se Tsamaeang ka Maeto
Bothata: Sefofane se fofa ka lebelo le sa fetoheng la 800 km/h. Ho tla nka nako e kae ho nka sebaka sa 2,400 km?
tharollo:
Ho hlophisa botjha equation \( d = vt \) ho rarolla \( t \):
\[
t = \frac{d}{v} = \frac{2400 \, \text{km}}{800 \, \text{km/h}} = 3 \, \text{h}
\]
Sefofane se tla nka dihora tse 3 ho tsamaya dikhilomithara tse 2,400.
### Mohlala oa 5: Sebapali sa Libaesekele se Tsitsitseng
Bothata: Mopalami oa baesekele o tsamaea ka lebelo le lekanang la 15 km/h. Ba tla be ba tsamaile sebaka se sekae ka mor'a lihora tse 6?
tharollo:
Ho sebelisoa equation \( d = vt \):
\[
d = 15 \, \mongolo{km/h} \makgetlo a 6 \, \mongolo{h} = 90 \, \mongolo{km}
\]
Ka hona, mopalami oa baesekele o tla tsamaea lik'hilomithara tse 90 ka lihora tse 6.
### Mohlala oa 6: Lerumo le Potlakileng
Bothata: Kulo e tsamaea moeeng ka tsela e otlolohileng ka lebelo le sa fetoheng la 1,200 m/s. E tla nka sebaka se sekae ka metsotsoana e 0.5?
tharollo:
Taba ea pele, etsa bonnete ba hore liyuniti lia tšoana. Mona, liyuniti tsohle li ka SI (limithara le metsotsoana).
Ho sebedisa \( d = vt \):
\[
d = 1200 \, \text{m/s} \times 0.5 \, \text{s} = 600 \, \text{m}
\]
Kahoo, kulo e tla koahela sebaka sa limithara tse 600 ka metsotsoana e 0.5.
### Mohlala oa 7: Koloi ea Peiso
Bothata: Koloi ea mabelo e tsamaea ka lebelo le sa fetoheng la lik'hilomithara tse 200 ka hora (mph). Haeba koloi e boloka lebelo lena, ho tla nka nako e kae ho tsamaea lik'hilomithara tse 400?
tharollo:
Ho sebedisa \( t = \frac{d}{v} \):
\[
t = \frac{400 \, \text{miles}}{200 \, \text{miles ka hora}} = 2 \, \text{lihora}
\]
Koloi ea mabelo e tla nka lihora tse 2 ho tsamaea lik'hilomithara tse 400.
### Mohlala oa 8: Lebanta la ho tsamaisa thepa
Bothata: Lebanta la conveyor le tsamaya ka lebelo le tsitsitseng la limithara tse 2 ka motsotsoana. Ho tla nka nako e kae hore ntho e tsamaiswe limithara tse 100 ho latela lebanta?
tharollo:
Ho sebedisa \( t = \frac{d}{v} \):
\[
t = \frac{100 \, \text{meters}}{2 \, \text{meters ka motsotsoana}} = 50 \, \text{seconds}
\]
Ho tla nka metsotsoana e 50 hore ntho eo e tsamaye dimithara tse 100 ka lebanta la conveyor.
### Mohlala oa 9: Sekepe se Tsitsitseng sa Likepe
Bothata: Sekepe sa seile se tsamaya ka lebelo le sa fetoheng la mafito a 12 (lik'hilomithara tsa likepe ka hora). Se tla be se tsamaile sebaka se sekae ka dihora tse 5?
tharollo:
Ho sebedisa \( d = vt \):
\[
d = 12 \, \text{knots} \times 5 \, \text{hours} = 60 \, \text{nautical miles}
\]
Sekepe sa seile se tla nka dimaele tse 60 tsa lewatle ka dihora tse 5.
### Mohlala oa 10: Sesesi
Bothata: Sesesi se sesa ka lebelo le tsitsitseng la limithara tse 2 ka motsotso. Bala hore na sesesi se tla se nka sebaka se sekae ka metsotso e 30.
tharollo:
Ho sebedisa \( d = vt \):
\[
d = 2 \, \text{meters ka motsotso} \times 30 \, \text{metsotso} = 60 \, \text{meters}
\]
Motho ea sesang o tla nka sebaka sa limithara tse 60 ka metsotso e 30.
## Qetello
Motsamao o ts'oanang o otlolohileng o fana ka mohlala o nolofalitsoeng bakeng sa ho utloisisa motsamao ka lebelo le sa fetoheng tseleng e otlolohileng. Ka ho hlahloba mehlala e mengata ea lefats'e la 'nete le ea khopolo-taba—ho tloha litereneng le lifofaneng ho ea ho bapalami ba libaesekele le likepe tsa seile—re bone kamoo equation ea motheo \(d = vt \) e re lumellang ho bolela esale pele le ho utloisisa likamano tsa sebaka, lebelo le nako motsamaong o ts'oanang o otlolohileng. Tsebo ea melao-motheo ena ha e ntlafatse kutloisiso ea motho ea fisiks ea motheo feela empa hape e hlomella motho ka lisebelisoa tse sebetsang tsa ho rarolla mathata mafapheng a fapaneng.
