Mokhoa oa ho Bala Lebelo le Tloaelehileng
Ho bala lebelo le tloaelehileng ke mohopolo oa motheo fisiks le bokhoni bo sebetsang bophelong ba letsatsi le letsatsi. Ebang u seithuti se lekang ho rarolla bothata ba phaposi ea ho ithuta, semathi se latelang tsoelo-pele ea hau, kapa mokhanni ea amehileng ka tšebeliso e ntle ea mafura, ho utloisisa mokhoa oa ho fumana lebelo le tloaelehileng ho bohlokoa. Sengoloa sena se tla arola mehato le ho fana ka mehlala e fapaneng ho bontša ts'ebetso ea ho bala lebelo le tloaelehileng.
Ho Utloisisa Lebelo le Tloaelehileng
Lebelo le tloaelehileng le hlalosoa e le sebaka sohle se tsamailoeng se arotsoeng ka nako eohle e nkiloeng ho tsamaea sebaka seo. Se fapane le lebelo le potlakileng, e leng lebelo ka nako efe kapa efe. Lebelo le tloaelehileng le fana ka pono e felletseng ea lebelo ka kakaretso leetong, ho fapana le ho tsepamisa maikutlo linakong tse itseng.
Foromo ea lebelo le tloaelehileng ke:
\[ \text{Average Lebelo} = \frac{\text{Total Sekgala}}{\text{Total Time}} \]
Foromo ena e otlolohile, empa ts'ebeliso ea eona e ka fapana ho latela moelelo. A re hlahlobeng mehato le mehlala ho fumana kutloisiso e hlakileng haholoanyane.
Tataiso ea Mohato ka Mohato ea ho Bala Lebelo le Tloaelehileng
Mohato oa 1: Lekanya Sebaka se Akaretsang
Mohato oa pele oa ho bala lebelo le tloaelehileng ke ho lekanya sebaka sohle se tsamailoeng. Sena e ka ba yuniti efe kapa efe ea sebaka joalo ka limithara, lik'hilomithara, limaele, jj. Netefatsa botsitso ba liyuniti tse sebelisitsoeng ho pholletsa le palo.
Mohlala: A re re o matha serapeng sa boikhathollo se nang le tsela ea ho matha ea lik'hilomithara tse 2, 'me u qetile marokho a 3. Sebaka sohle e tla ba:
\[ \text{Total Sekgala} = 3 \text{ laps} \times 2 \text{ km/lap} = 6 \text{ km} \]
Mohato oa 2: Lekanya Kakaretso ea Nako
Ka mor'a moo, o hloka ho lekanya nako eohle e nkiloeng ho koahela sebaka. Nako ena e ka tlalehoa ka metsotsoana, metsotso, lihora, jj., empa e tlameha ho bapisa yuniti ea sebaka bakeng sa lipalo tse nepahetseng.
Mohlala: Haeba ho u nka metsotso e 30 ho qeta lik'hilomithara tse 6, fetola nako ena hore e be yuniti e tsitsitseng haeba ho hlokahala. Bakeng sa bonolo, ha re e boloke ka metsotso e seng mekae:
\[ \mongolo{Nako yohle} = 30 \mongolo{metsotso} \]
Mohato oa 3: Sebelisa Foromo ea Lebelo le Arolelanoang
Ka kakaretso ea sebaka le kakaretso ea nako e lekantsoe, sebelisa foromo:
\[ \text{Average Lebelo} = \frac{\text{Total Sekgala}}{\text{Total Time}} \]
Mohlala: Ho tsoa litekanyong tsa rona tsa pele,
\[ \text{Average Lebelo} = \frac{6 \text{ km}}{30 \text{ min}} = 0.2 \text{ km/min} \]
Bakeng sa merero e sebetsang, o kanna wa batla ho fetola sena hore e be yuniti e ka amanang haholoanyane, joalo ka lik'hilomithara ka hora (km/h):
\[ 0.2 \mongolo{ km/min} \makgetlo a 60 \mongolo{ min/hora} = 12 \mongolo{ km/h} \]
Mohato oa 4: Liphetoho le Litlhokomelo tsa Moelelo
– Diyuniti tsa Tekanyo: Kamehla etsa bonnete ba hore diyuniti tse sebediswang di a tsitsa. Ho kopanya diyuniti (mohlala, dikhilomithara le dihora) ho hloka phetoho e loketseng.
– Maemo: Haeba leeto le kenyelletsa maoto a fapaneng ka lebelo le maemo a fapaneng, o kanna wa hloka mokhoa o boima.
Mohlala o nang le Likarolo tse Ngata
A re re o nkile leeto la koloi moo leeto le neng le arotsoe likarolo tse peli. Karolong ea pele, o tsamaile lik'hilomithara tse 50 ka hora e le 'ngoe. Karolong ea bobeli, o tsamaile lik'hilomithara tse 100 ka lihora tse 2.
Palo ea Mohato ka Mohato:
1. Bala Kakaretso ea Sebaka:
\[ \text{Bohōle Bohle} = 50 \text{ km} + 100 \text{ km} = 150 \text{ km} \]
2. Bala Kakaretso ea Nako:
\[ \text{Nako yohle} = 1 \text{lihora} + 2 \text{lihora} = 3 \text{lihora} \]
3. Sebelisa Foromo:
\[ \text{Average Lebelo} = \frac{150 \text{ km}}{3 \text{ dihora}} = 50 \text{ km/h} \]
Litšebeliso tse Sebetsang tsa Lebelo le Tloaelehileng
Driving
Ho utloisisa lebelo la hao le tloaelehileng ho thusa ho hakanya nako ea ho tsamaea le tšebeliso ea peterole. Haeba mokhanni a tseba hore lebelo la hae le tloaelehileng tseleng e kholo ke 70 km/h 'me a hloka ho tsamaea lik'hilomithara tse 280, a ka hakanya:
\[ \text{Nako ea Maeto} = \frac{280 \text{ km}}{70 \text{ km/h}} = 4 \text{lihora} \]
Ho Matha le ho Palama Baesekele
Baatlelete ba sebelisa lebelo le tloaelehileng ho lekanya ts'ebetso ea bona le ho ntlafatsa boikoetliso. Mohlala, mopalami oa baesekele ea rerang ho palama lik'hilomithara tse 90 ha a ntse a boloka lebelo le tloaelehileng la 30 km/h o lebeletse ho qeta leeto ka:
\[ \text{Nako e Hlokahalang} = \frac{90 \text{ km}}{30 \text{ km/h}} = 3 \text{lihora} \]
Sebaka le Lifofane
Lipalo tse tloaelehileng tsa lebelo ke tsa bohlokoa maetong a lifofane le a sepakapaka moo nako le libaka tse nepahetseng li leng bohlokoa. Sefofa-sebakeng se koahelang libaka tse kholo se hloka lipalo tse nepahetseng tsa lebelo bakeng sa ho rala le ho phethahatsa thomo.
Menahano e phethang
Ho bala lebelo le tloaelehileng ke bokgoni bo nolofatsang kutlwisiso le ho ntlafatsa dikarolo tse fapaneng tsa mesebetsi ya letsatsi le letsatsi le boiteko ba saense. Ebang o ntlafatsa leeto la ho ya mosebetsing, o ikoetlisetsa marathone, kapa o rera leeto, melaomotheo e dula e tshwana: lekanya sebaka sohle le nako yohle ka nepo, sebedisa foromo, mme o nahane ka diphetoho dife kapa dife tsa moelelo. Sena ha se thuse feela ditshebedisong tse sebetsang empa hape se tebisa kutlwisiso ya hao ya motsamao le fisiks.
Ka ho tseba ho bala lebelo le tloaelehileng, o itlhomella ka sesebelisoa sa bohlokoa bakeng sa maemo a fapaneng a tlhahlobo le a sebetsang, e leng se ntlafatsang bokgoni le katleho.
