Newton's Cannon
Mẽne ne wannan? Isaac Newton ya yi tunanin wani makami a kan dutse mai tsayi wanda zai fito daga sama. Ka yi wuta da kwallon kadan kuma ta fadi ƙasa. Ka yi wuta da shi, da sauri, kuma ƙasa ta karkata daga ƙarƙashinsa kamar yadda take fãɗuwa, sabõda haka bã za ta iya fãɗuwa ba. Wannan wata tafiya ce.
Yadda ake amfani da shi: Ka ƙayyade gudun farawa da slider ko maɓallin gudu, sa'an nan ka danna Shotgun. Zaɓuɓɓukan farko na iya zama a kan fuskar kwamfyuta don ka iya kwatanta su.
Yaya wannan yake?
- Your shot
- Jirgin sama na jiragen ruwa, kusan 900 km/h (0.25 km/s)
- Bullet, a kan 1 km/s
- Orbit speed
- Escape speed
An yi zane da dutsen ya fi tsayi fiye da duk wani na gaskiya don ka iya ganinsa. An manta da juriya ta iska.
Yi wannan
- Danna "Jet airliner" kuma ka yi wuta, sa'an nan kuma "Rifle bullet" kuma ka yi wuta.Bayani: Har ma da abubuwa masu sauri na yau da kullum ba su da sauri sosai don su iya tafiyar da wata.
- Danna "Saurin Orbit" kuma ka yi wuta.Bayani: An yi wa kwallon wani juyawa har sai ta dawo cikin bindigar. Takan faɗi duk lokacin da take faɗuwa, amma tana ci gaba da rasa ƙasa. Wannan shi ne yadda Tashar Samaniya ta Duniya ke zama a sama.
- Fire a little slower than orbit speed, then a little faster.Bayani: Mai sauri: yana juyawa ƙasa kuma ya tashi a wani ɓangaren hanya. Mai sauri: daurin yana faɗaɗawa zuwa wani tsawo mai launin shuɗi wanda ke juyawa zuwa waje kuma yana dawowa.
- Danna "Saurin gudu" da wuta, sa'an nan kuma canja duniyar zuwa wata.Bayani: A cikin gudun gudu, kwallon tana tafiya kuma ba ta dawo ba. A kan wata, da ƙarfin jujjuyawarta mai rauni, gudun orbit ɗinta yana kusa da 1.6 km/s kawai.
The ideas behind it
Me ya sa bawul din da ke tafiyar hawainiya bai fadi ba?
Yana faruwa, duk lokacin. Fuskar ƙasa tana canzawa zuwa ƙasa da mita 5 ga kowace kilomita 8 da kake tafiya, kuma duk abin da aka jefa yana faruwa da mita 5 a cikin minti na farko. Saboda haka kwallo mai motsi a gefen da kilomitara 8 a kowane sakan yana faruwa da mita 5 a kowane sakan yayin da ƙasa ke faruwa da mita 5. Ba ta taba kusantar ƙasa ba.
Me ya sa wannan dutse mai tsayi?
A kan ƙasa, dutsen nan yana da tsayin kilomita 510 (8% na radius din ƙasa), mafi girma fiye da inda Tashar sararin samaniya ta duniya take tashi (kimanin kilomita 400), don haka kwallon tana farawa a sama da kusan dukkan hasken rana. A cikin hasken rana, jujjuyawar za ta rage gudun kuma ta sanya kwallon ta zafi sosai kafin ta kai ga sauri mai tafiyar wata. Wannan shi ne dalilin da ya sa manyan rokets ke tashi daga sama farko kuma su kara gudu zuwa gefe.
Maɗaukaki: masu duniyar da girmansu daga NASA/JPL (bodies.json); hanyoyin sune daidaitattun orbits na jiki biyu. Saurin yau da kullum suna da siffofi masu kyau: jiragen sama na jirgin ruwa suna tafiya a cikin kusan 900 km/h, kuma bular bindigar ta bar bututun a cikin kusan 0.7 zuwa 1.2 km/s, kusan 1 km/s ga mai sauri.
Wannan ya sa duk wani abu yana da karfin jujjuyawar da yake da shi a kan sauran abubuwa.
