Umlilo webhola le-cannon olusheshayo futhi olusheshayo kusuka engxenyeni ephezulu yedolobhana kuze kube se-orbit, bese uphuma.

I-Cannon kaNewton
Yini lokhu? UIsaac Newton wacabanga nge-cannon esitezi esiphakeme kakhulu ukuthi siphuma emkhathini. Yivule ibhola kancane futhi lizobuyela phansi. Yivule ngokushesha okukhulu futhi indawo izoba phezulu ngaphansi kwayo njengoba lihamba ngokushesha, ngakho akufanele lihlale. Lokhu kuyi-orbit.
Indlela yokusetshenziswa kwayo: Misela isivinini sokuqapha nge-slider noma inkinobho yesikhathi, bese ucindezela i-Fire. Izinhlamvu ezidlule zihlala kusikrini ukuze ukwazi ukuziqhathanisa.
Ingabe ihamba ngokushesha?
- Ushoda lwakho
- Indiza ye-jet, cishe amakhilomitha angama-900/h (amakhilomitha ayi-0.25/s)
- Ibhombu le-rifle, cishe amakhilomitha angu-1/s
- Isivinini se-orbit
- Isivinini sokuyeka
I-mountain izotshwa phezulu kunanoma iyiphi enye ekhona ukuze ukwazi ukuyibona. Ukumelana nomoya kulahlekile.
Zama lokhu
- Chofoza "I-Jet airliner" bese ushaya, bese ucindezela "Rifle bullet" bese ushaya.Isixhumanisi: Zonke zibuyela phansi ngasikhathi sinye. Nakuba izinto ezihamba ngokushesha kakhulu, azikho lapho zingahamba khona ngokushesha ngokwanele ukuze zihambe nge-orbit.
- Chofoza "Ijubane le-Orbit" bese ushaya.Isixhumanisi: Ibhola lihamba yonke indlela libuyela emuva ekhanda lempuphu. Lisenyakatho isikhathi esigcwele, kodwa lihlala lishiya izulu. Lokhu kuyindlela i-International Space Station ihlala ngayo phezulu.
- Umlilo uhamba kancane ngaphezu kwejubane le-orbit, bese uhamba ngokushesha.Isixhumanisi: Ehamba kancane: ijika phansi futhi iwela endaweni encane yendlela. Ihamba ngokushesha: ijikelezo lisuka ku-oval ende elihamba phambili libuyela emuva.
- Chofoza "Ijubane lokuyeka" bese ushaya, bese ushintsha iplanethi ibe nguMhlaba.Isixhumanisi: Kukhawulo lokuyeka ibhola liphuma futhi alibuyeli. Enyangeni, nge-gravity yayo encane, isantya sokuhamba siyi-1.6 km/s kuphela.
Izinhlamvu ezimqoka
Kungani ibhola elijikelezayo liphansi?
Iwela, yonke isikhathi. Isimo sezulu sihamba phezulu ngamamitha ayi-5 nganoma yiziphi izikhilomitha ezingu-8 ozihambayo, futhi noma yini ehla iwela ngamamitha angama-5 kwisiqingatha sayo sokuqala. Ngakho-ke ibhola elihamba ngakwesobunxele ngamakhilomitha angama-8 ngesiqingatha siwela ngamamitha angama-5 ngalesiqingatha kanti indawo ihlala iphansi ngamamitha angama-5. Ayikho into efinyelela phansi kakhulu.
Kungani kukhona i-mountain ephakeme?
Ezweni idolobhana liyi-510 km ubude (8% ye-radius yezwe), ngaphezu kwe-International Space Station endizayo (imalunga ne-400 km), ngakho ibhola liqala phezulu kakhulu komoya wonke. Ehla emkhathini, ukudonsa kuzonciphisa futhi kufudumeze ibhola isikhathi eside ngaphambi kokuba lifike kwijubane le-orbit. Lokhu yisizathu sokuthi kungani ama-rockets angempela enyuka ngaphandle komkhathini kuqala bese ehamba ngokushesha ngakwesobunxele.
Amasu: amaplanethi nama-mass kanye nezilinganiso kusuka ku NASA/JPL (bodies.json); imizila yimijikelezo efanele yezinto ezimbili. Ijubane losuku lonke liyisilinganiso esijwayelekile sezinhlamvu ezijikelezayo: izindiza zejet zihamba ngamakhilomitha angama-900 ngehora, futhi amabhuleki wempuphu ashiya ibhodlela ngamamitha ayi-0.7 kuya kumakhilomitha ayi-1.2 ngesekondi, cishe amakhilomitha ayi-1 ngesekondi uma uhamba ngokushesha.
Ukudonsa okuthile okunye. Ubunzima beplanethi budonsa konke kuhamba phambili, ngakho izinto ziwela phansi.
Okuningi ku-glossary →Indlela yesona sinye isitho esiqhubeka nokuwa ngaphesheya kweplanethi noma i-star ngaphandle kokushaya, ngoba sihamba ngejubane elifanele.
Okuningi ku-glossary →Isivinini okufanele uhambe ngakwesobunxele ukujikeleza iplanethi ephakeme kakhulu ngaphandle kokugwaza noma ukugibela. Ngaphakathi kwezulu lezwe liyi-7.8 km/s.
Okuningi ku-glossary →Isivinini esidingekayo ukushiya iplanethi ngokulungile, kungase kudlule. Kusuka ebusweni bezwe yi-11.2 km/s, ngaphandle kokubona umoya.
Okuningi ku-glossary →Umoya ucindezela into ehambayo futhi uyikhawulele. Lezi zisetshenziswa azibonisi lokhu; ibhola le-cannon elizwakalayo elifihliwe ngale ndlela lizomiswa futhi liqhume ngumoya.
Ithebula ledatha (ukhetho lombhalo)
Ehamba kancane kunejubane lokujikeleza: libuyela emuva. Kuphakathi kwejubane lokujikeleza nelokuphuma: lijikeleza. Kuye noma ngaphezu kwejubane lokuphuma: lishiya ngokugcwele.
| Iplanethi | Isivinini sokuhamba nge-orbit esijikelezayo lapha | Isivinini sokuyeka lapha |
|---|---|---|
| Umhlaba | 7.61 km/s | 10.8 km/s |
| Inyanga | 1.62 km/s | 2.29 km/s |
| UMarzi | 3.42 km/s | 4.84 km/s |
Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
