Cannon ya Newton
Mphamvu ya cannonball mofulumira ndi mofulumira kuchokera pamwamba pa phiri mpaka orbits, ndiye kugwa.

Cannon ya Newton
Kodi ndi chiyani? Isaac Newton anaganiza kuti pali kanoni pa mtsinje wotsika kwambiri kuti umatuluka m'nyanja. Mphatso ya mpira imayenda mofulumira ndipo imakhala yotsika. Mphatsoyo imayenda mofulumira kwambiri ndipo dziko lapansi limazungulira pansi pake mofulumira monga momwe ikuyendera, kotero sichidzatha kulowa. Izi ndi orbit.
Momwe mungagwiritsire ntchito: Sankhani kukhazikitsa mzere ndi slider kapena batani la mzere, ndiyeno dinani Fire. Kujambula zapitazo zimakhala pazenera kuti muthe kuziyerekezera.
Kodi ndiyosavuta?
- Kugwa kwanu
- Jet ndege, za 900 km / h (0.25 km / s)
- Mphamvu ya mkuwa, pafupifupi 1 km / s
- Kuyenda
- Kuthamanga kwa Escape
Mtsinje ukhoza kuwonedwa chifukwa cha kutalika kwake, komabe, kukana kwa mpweya sikunaganizidwe.
Pezani izi
- Press "Jet ndege" ndi moto, ndiye "Rifle bullet" ndi moto.Kudziwitsa: Omwewo amagwa pansi pafupifupi nthawi imodzi. Ngakhale zinthu za tsiku ndi tsiku zofulumira kwambiri sizikupezeka pafupi ndi mwachangu kwambiri kuti zikhale m'mimba mwake.
- Press "Orbit liwiro" ndi moto.Kudziwitsa: Mpira umakhala wozungulira nthawi zonse ndipo umabwerera ku kanoni. Umakhala ukugwa nthawi zonse, koma umapita pansi. Ndi choncho kuti International Space Station imakhazikika.
- Mphamvu ya moto pang'onopang'ono kuposa kuzungulira kwa mpweya, kenako pang'onopang'ono.Kudziwitsa: M'njira yofulumira: chilumbacho chimayenda m'mphepete mwa nyanja ndipo chimakhala ndi mapiri ozungulira, omwe amawoneka ngati mapiri amtundu wa oval.
- Press "Escape kufulumira" ndi moto, ndiye kusintha dziko lapansi kuti mwezi.Kudziwitsa: Pa escape galimoto mpira amapita ndi sichibwereranso. Pa Mwezi, ndi kupweteka kwake kocheperako, kuthamanga kwa orbit ndi pafupifupi 1.6 km / s.
Maganizo m'mbuyomu
N'chifukwa chiyani mpira wozungulira umagwa pansi?
Zimagwa nthawi zonse. Mtundu wa dziko lapansi umayenda pansi ndi mamita 5 kwa makilomita 8 omwe mumayenda, ndipo chilichonse chomwe chimatuluka chimatuluka pafupifupi mamita 5 munthawi yake yoyamba. Kumbukirani kuti mpira womwe umayenda m'mbali mwake ndi mamita 8 pa mphindi umakhala wotsika mamita 5 pa mphindi pamene dziko lapansi limatsika m'mbali mwake m'milimita 5.
N’chifukwa chiyani pali mlimi wochuluka?
Padziko lapansi, mlimiwu uli ndi kutalika kwa makilomita 510 (8% ya mtunda wa dziko lapansi), ndipo ndi pamwamba pa ndege za International Space Station (makilomita 400), choncho mpira umayamba pansi pa madzi onse. M'madzi, kukana kumatha kuchepetsa ndi kutentha mpira nthawi yayitali pambuyo pake kuti afike pa liwiro la orbit.
Zizindikiro: masa a planet ndi kukula kwa NASA/JPL (bodies.json); maulendo ndi mfundo awiri-thupi orbits.Everyday kufulumira ndi typical round zigawo: jet ndege cruise pa pafupifupi 900 km / h, ndi zitsulo zinyalala kuchoka chitoliro pa pafupifupi 0.7 mpaka 1.2 km / s, za 1 km / s kwa mphindi imodzi.
Kuvuta kwa dziko lapansi kumatenga chilichonse kudzera m'malo ake, chifukwa chake zinthu zimagwa.
Kuwonjezera pa mawu ofotokoza →Mtunda wa chinthu chomwe chimayenda mozungulira planeta kapena nyenyezi popanda kuwononga, chifukwa chimayenda m'mbali mwake mofulumira.
Kuwonjezera pa mawu ofotokoza →Kuthamanga komwe muyenera kupita kumbuyo kuti muzungulire dziko lapansi pamalo operekedwa osagwa kapena kunyamula mbali. Just above Earth's air it is about 7.8 km/s.
Kuwonjezera pa mawu ofotokoza →Kuthamanga kofunikira kuti mupite padziko labwino, osabwereranso. Kuchokera pamalo a dziko lapansi, ndi pafupifupi 11.2 km / s, osaganizira za mpweya.
Kuwonjezera pa mawu ofotokoza →Kuthamanga kwa mpweya kukhudza chinthu choyenda ndikuichepetsa. Izi sizidzachitikirani; kanoni yachilendo yophimbidwa mofulumira kwambiri ikhoza kulephera ndi kuwonongedwa ndi mpweya.
Tabula ya deta (malemba osiyanasiyana)
Kuthamanga pang'ono kuposa kuzungulira: imabwerera. Pakatikati pa kuzungulira ndi kutuluka kwamphamvu: imayenda m'mphepete mwake. Pa kapena pamwamba pa kutuluka kwamphamvu: imachoka kwabwino.
| Planet | Kuzungulira kwa mtunda woyenda | Kutuluka m'njira |
|---|---|---|
| Dziko | 7.61 km/s | 10.8 km/s |
| Mwezi | 1.62 km/s | 2.29 km/s |
| Mars | 3.42 km/s | 4.84 km/s |
Zipangizo ndi zitsanzo zimagwiritsa ntchito mapangidwe osinthidwa kuti aziphunzira okha. Sayenera kugwiritsidwa ntchito poyendetsa, kupanga miyezo kapena kukhazikitsa njira iliyonse yogwiritsira ntchito. Onani zoletsa za masamba ophunzitsa
