Tanthauzo la kayendedwe kosagwirizana
Kuyenda kosagwirizana ndi mzere ndi kuyenda kothamanga nthawi zonse. Mwa kuyankhula kwina, kuyenda kosagwirizana ndi mzere = kuyenda ndi kukula kwa kuthamanga nthawi zonse ndipo njira yothamangira nthawi zonse. Njira yothamangira nthawi zonse ndi yokhazikika = njira ya liwiro ndi yokhazikika = njira yosunthika ndi yokhazikika = njira yoyenda nthawi zonse = njira yoyenda nthawi zonse = njira yoyenda nthawi zonse = chinthu chimayenda molunjika. Kukula kwa kuthamanga nthawi zonse kumatanthauza kuti kukula kwa liwiro kapena liwiro kumawonjezeka nthawi zonse.
Chitsanzo choyamba:
Chinthu choyamba chimakhala chili pampando. Pambuyo pa sekondi imodzi, chinthucho chimayenda pa liwiro la 2 m/s. Pambuyo pa masekondi awiri, chinthucho chimayenda pa liwiro la 4 m/s. Pambuyo pa masekondi atatu, chinthucho chimayenda pa liwiro la 6 m/s. Pambuyo pa masekondi anayi, chinthucho chimayenda pa liwiro la 8 m/s. Ndi zina zotero...
Sekondi imodzi iliyonse, liwiro la chinthucho limawonjezeka ndi 2 m/s. Chinthucho chimathamanga mosalekeza kwa 2 m/s pa sekondi imodzi kapena 2 m/s pa sekondi imodzi kapena 2 m/s 2.
Chitsanzo chachiwiri:
Chinthu chimayamba kuyenda pa liwiro la 10 m/s. Pambuyo pa sekondi imodzi.
Liwiro limachepetsedwa kufika pa 9 m/s. Masekondi awiri pambuyo pake, liwiro limachepa kufika pa 8 m/s. Masekondi atatu pambuyo pake, liwiro limachepa kufika pa 7 m/s. Masekondi anayi pambuyo pake, liwiro limachepa kufika pa 6 m/s. Ndi zina zotero ... Sekondi imodzi iliyonse, liwiro la chinthucho limachepa ndi 1 m/s. Chinthucho chimakhala ndi kutsika kosalekeza kwa 1 m/s pa sekondi imodzi kapena 1 m/s pa sekondi imodzi kapena 1 m/s 2.
Kuyerekeza kwa kayendedwe kosagwirizana
Pali njira zitatu za equation zomwe zimagwiritsidwa ntchito nthawi zambiri:
v t = vo + pa
d = vot + 1⁄2 pa 2
v t 2 = vo o 2 + 2 malonda
v o = liwiro loyambirira (mita/sekondi), v t = liwiro lomaliza (mita/sekondi), a = kufulumira (mita/sekondi), t = nthawi yopuma (sekondi), d = mtunda (mita).
Chitsanzo cha vuto 1:
Tinthu tating'onoting'ono, poyamba tikakhala pansi, timatha kuthamanga nthawi zonse kwa 2 m/s 2 kwa masekondi 10. Werengani liwiro lomaliza la tinthu tating'onoting'ono.
yankho;
Popanda equation:
Kuthamanga (a) = 2 m/s 2 zikutanthauza kuti liwiro (v) likuwonjezeka ndi 2 m/s sekondi imodzi iliyonse. Pambuyo pa masekondi awiri, v = 4 m/s. Pambuyo pa masekondi 10, v = 20 m/s.
Kugwiritsa ntchito equation:
Zodziwika: v o = 0 m/s (tinthu tating'onoting'ono tomwe tili pamalo opumulira), a = 2 m/s 2 , t = 10 s
Ankafuna: v t
v t = vo o + pa = 0 + (2)(10) = 20 m/s
Chitsanzo cha vuto 2:
Galimoto imayenda molunjika pa liwiro la 60 km/h. Chifukwa pali chopinga, dalaivala amayendetsa mabuleki, kotero galimotoyo imathamanga pang'onopang'ono ndi 10 m/s2. Kodi galimotoyo imayendabe mtunda wotani mpaka itaima pambuyo poti mabuleki atha?
Zodziwika:
v o = 60 km/h = 60(1000 m)/3600 s = 17 m/s
v t = 0 m/s (mayimidwe a magalimoto)
2a = – 10 m/s
Kufunidwa: mtunda (d)
yankho;
v t 2 = vo o 2 + 2 malonda
(0) 2 = (17) 2 + 2(-10) d
0 = 289 – 20 masiku
289 = 20 d
d = 289 : 20 = mamita 14.45
Chitsanzo cha vuto 3:
Chithunzi chomwe chili pansipa ndi graph yoyenda yosagwirizana, v ikuyimira liwiro, ndipo t imayimira nthawi. Kukula kwa kuthamanga kwa zinthu kutengera graph ndi ...
Chitsanzo cha vuto 4:
Kuyenda kwa galimoto kumapanga tchati cha liwiro (v) vs nthawi (t) monga momwe zasonyezedwera pachithunzi chomwe chili pambali. Ngati dera lomwe lili pansi pa graph (dera lokhala ndi mthunzi) ndi 48 m, ndiye kuti kuthamanga kwa galimotoyo ndi ...
Malo okhala ndi mthunzi = mtunda wonse = mamita 48
v o = 8 m/s, v t = 16 m/s, t = 1 m/s
v t = vo + pa
16 = 8 + a (1)
a = 16 – 8
a = 8 m/s 2

Mafunso ndi mayankho okhudza kayendetsedwe ka mzere kosagwirizana
- Kodi kuyenda kosagwirizana kwa mzere n'chiyani?
Kuyenda kosagwirizana kwa mzere kumatanthauza kuyenda kwa chinthu motsatira mzere wowongoka ndi liwiro losintha kapena liwiro.
- Kodi kuyenda kosagwirizana kwa mzere kumaimiridwa bwanji pa graph ya mtunda-nthawi?
Kuyenda kosagwirizana kwa mzere kumaimiridwa ndi mzere wokhota pa graph ya mtunda-nthawi.

Inde, 'displacement 's' ikhoza kukhala yoipa mu kayendedwe kosagwirizana kolunjika. Izi zingasonyeze kuyenda kosiyana ndi njira yabwino yosankhidwa.
- Kodi n'zotheka kuti chinthu choyenda molunjika chosagwirizana chiyime?
Inde, chinthu chomwe sichikuyenda mofanana chingayime ngati kuthamanga kwake kukuchita zinthu mosiyana ndi komwe chikuyenda ndipo kumachepetsa kwambiri liwiro la chinthucho kufika pa zero.
- Kodi njira yogwiritsira ntchito liwiro lomaliza mu kayendedwe kosagwirizana ndi mzere ndi iti, poganizira liwiro loyambirira, kuthamanga, ndi nthawi?
Fomula ndi v = u + at, pomwe v ndi liwiro lomaliza, u ndi liwiro loyambirira, a ndi kufulumira, ndipo t ndi nthawi.
- Kodi lingaliro la jerk limagwira ntchito bwanji pa kayendedwe kosagwirizana ndi mzere?
Kuthamanga ndi liwiro la kusintha kwa kuthamanga. Mu kayendedwe kosagwirizana, ngati kuthamanga sikuli kokhazikika ndipo kumasintha pakapita nthawi, ndiye kuti kuthamanga kulipo.
