Theuniform rectilinear motsi (MRU) Motsi ne wanda ake yin sa a kan madaidaiciyar layi, cikin saurin gudu (tare da girma da shugabanci akai).
Hanya ita ake kira tafarkin da wani abu ke bayyana lokacin motsi daga wannan aya zuwa wani. Physics yana rarrabe motsi ta yanayin su:
Rectilinear. Ana yin ta ne ta hanya ɗaya kawai.
- Uniform. Gudun yana da ƙarfi, hanzarinsa ba komai.
- An hanzarta. Hanzarta akai -akai, wato gudun yana ƙaruwa ko raguwa ta hanyar da ta dace.
Mai lankwasa.
- Pendular. Motsawa ce mai motsi, kamar ta pendulum.
- Madauwari. Tare da axis na juyawa da radius na yau da kullun. Hanyar motsi tana kwatanta da'irar.
- Parabolic. Hanyar abu ta jawo parabola.
Cewa motsi iri ɗaya ne yana nufin cewa saurin sa akai ne, saurin sa baya canzawa. Hanzarta ba komai.
Gudu shine adadi wanda aka ayyana azaman nisan tafiya a cikin naúrar lokaci. Misali: Kilomita 40 a awa daya yana nufin wayar tafi da gidanka tana tafiya kilomita 40 a cikin awa daya (kilomita 40 / h).
Don lissafin tazarar da wani abu ke tafiya tare da madaidaicin madaidaicin motsi, ana amfani da bayanai masu zuwa: sauri da lokaci.
Idan kun san nisa da saurin amma kuna son lissafin lokacin da zai ɗauka, raba tazara da saurin:
d / v = t50 km / 100 km / h = 1/2 h (0.5 h)
Hakanan zaka iya gano saurin idan kuna da tazara da bayanan lokaci:
D / t = V50 km / ½ h = 100 km / h
A takaice dai, halayen motsin madaidaicin motsi (MRU) sune:
- Hanyar madaidaiciya
- Gudun gudu (uniform)
- Hanzarta Zero
- Hanyar madaidaiciya
- Duba kuma: Fada ta kyauta da jifa na tsaye
Misalan motsi madaidaiciya madaidaiciya
- Jirgin kasa ya bar Paris da karfe 6 na safe kuma ya isa Lyon da karfe 8 na safe. Hanyarsa tana kan layi madaidaiciya. Nisa tsakanin Gare de Paris da Gare de Lyon shine kilomita 400. Jirgin kasa koyaushe yana tafiya cikin sauri iri ɗaya, ba tare da yin hanzari ko birki ba har ya isa inda ya nufa. Yaya sauri jirgin yake tafiya?
Nisa: Kilomita 400
Yanayi: 8 hours - 6 hours = 2 hours
400 km / 2 hours = 200 km / h
Amsa: jirgin yana tafiya kilomita 200 a awa daya.
- Hanyar daga gidana zuwa gidan abokina madaidaiciya ce. A duk lokacin da na ziyarce ta, ina tuka motata da gudun kilomita 20 a cikin sa'a guda, ba tare da yin hanzari ko rage gudu ba har na isa wurin. Yana ɗaukar ni rabin sa'a kafin in isa wurin.
Yaya gidan abokina yake?
Gudun: 20 km / h
YanayiKu: 1/2 h
20 km / h / 1/2 h = 10 km
Amsa: gidan abokina yana da nisan kilomita goma.
- Juan yana ba da jaridu a unguwarsa. Kamar yadda ya san adiresoshin da zuciya, sai ya hau kan babur ɗinsa ya yi tafiyarsa ba tare da tsayawa ba lokacin da ya isa kowane gida, a maimakon haka ya jefar da jaridu daga babur ɗin. Hanyar Juan tana kan hanya ɗaya, madaidaiciya, na kilomita 2. Yana tafiya da gudun kilomita 10 a awa daya. Dole ne Juan ya fara balaguron sannan ya koma kan wannan titin cikin sauri. Idan Juan ya tafi yanzu, yaushe zai dawo?
A wannan yanayin akwai motsi madaidaiciya madaidaiciya guda biyu: ɗayan yana tafiya da ɗayan baya.
Gudun: 10 km / h
NisaKu: 2 km
2 km / 10 km / h = 0.2 h = mintuna 12
Wannan lissafin na ɗaya daga cikin rangadin ne.
Minti 12 x 2 (tafiya zagaye) = mintuna 24
Amsa: Juan zai dauki mintuna 24 kafin ya dawo.
- Kowace safiya ina gudu kilomita goma kai tsaye tare da rairayin bakin teku, kuma yana ɗaukar ni awa 1. Ina so in inganta saurin gudu don yin tsere da mai fafatawa da ni, wanda zai iya yin gudun kilomita 12 a awa daya. Yaya tsawon lokacin da zan ɗauka in hau abin da na saba hawa don tashi da sauri tare da mai fafatawa da ni?
Gudun: 12 km / h
NisaKu: 10 km
10 km / 12 km / h = 0.83 h = mintuna 50
Amsa: Dole ne in kammala kwas ɗin a cikin mintuna 50 don yin sauri kamar mai gasa ta.
- Ci gaba da: Ƙirƙirar Ƙara
