Newton's Cannon
Chii ichi? Isaac Newton akafunga nezvemugwagwa wakakwira kwazvo kuti uenderere mberi kubva mumhepo. Usati waisa mvura, bvisa bhodhoro uye richadzokera pasi. Usati waisa mvura, bvisa bhodhoro nekukurumidza sezvazvinogona uye nyika ichazvibata ichibva pasi pebhodhoro zvakaomarara sezvairi kubuda, saka hachizombomira. Izvi zvinonzi orbit.
Maitiro ekuishandisa: Seta kuvhura speed ne slider kana speed bhatani, wobva wadzima moto. Vatsva shots vanogara pascreen kuti ugone kuvaenzanisa navo.
Chii chinonzi speed?
- Kubuda kwako
- Jet ndege, pamusoro 900 km / h (0.25 km / s)
- Rifle bullet, pamusoro 1 km / s
- Orbit speed
- Kubuda-munzira
Mugwagwa unoratidzwa semugwagwa wakakwira kupfuura chero mumwe wacho, saka unogona kuona kuti ndeupi.
Tarisa izvi
- Tinya "Jet ndege" uye moto, wobva wasarudza "Rifle bullet" uye moto.Nharaunda: Vaviri vacho vanodzokera pasi zvakaenzana. Kunyangwe zvinhu zvinofamba nekukurumidza kwazvo mazuva ese hazvina kunyatsosvika pakutenderera.
- Tinya "Orbit speed" uye moto.Nharaunda: Bhora rinofamba nenguva yose uye rinovakazve kukanzura. Rinokwira nguva dzose, asi rinotoramba risina kusvika pasi. Izvi ndizvo zvinoita kuti International Space Station igare ichimira.
- Fire a little slower than orbit speed, then a little faster.Nharaunda: Kuomarara: inokurumidza kutenderera uye inokwira pasi. Kuomarara: inofamba nekumhanya kwakanyanya. Kuomarara: inoramba ichienda pasi, asi ichidzokera kumashure.
- Tinya "Escape speed" uye moto, wobva wachinja nyika kuenda kuMweya.Nharaunda: At escape speed the ball leaves and never comes back. On the Moon, with its weaker gravity, orbit speed is only about 1.6 km/s.
Maitiro ari kutevera
Nei mutambo webhola uchifamba mumigwagwa usina kusvikira wadzikiswa?
Zvinenge zvakaoma kumbofunga kuti mvura inobuda muvhu inobva kupi? Asi zvinoitika, nguva dzose. Panzvimbo yenyika inotenderera pasi ne5 metres pamakore 8 iwe uchifamba, uye chero chinhu chinobuda chinobuda ne5 metres munguva yekutanga. Saka bhodhoro rinofamba kumashure ne8 kilometres per second rinobuda ne5 metres pamwedzi, asi nyika ichibva yasvika pasi ne5 metres.
Nei ichi chiri chikepe chakakura?
Panyika, mahombekombe aya ane 510 km (8% yemativi epasi) uye ari pamusoro penzvimbo iyo International Space Station inofamba (inenge 400 km), saka bhodhi rinotanga richikwira pasi pemhepo. Mumhepo, kumanikidza kunowedzera uye rinopisa bhodhi kwenguva yakareba usati wasvika pasimba rekumhanya kweorbit.
Izvo: marudzi eplaneti uye madiki kubva ku NASA/JPL (bodies.json); nzira dziri zvakajeka zviviri-zvisikwa orbits. Zvimwe zvinoitika zuva nezuva ndezvekutenderera zviratidzo: ndege dzendege dzinofamba pa900 km / h, uye mabhureki emaruva anobuda mubhazi pa0.7 kusvika 1.2 km / s, pamusoro pe1 km / s kune imwe nhanho.
Kunyangwe zvinhu zvese zviri pasi penyika zvinofamba zvakaenzana, kuoma kwepasi kunobata zvinhu zvese zvichienda kumashure.

Panguva ino, iyo mhepo inogara ichifamba nesimba rayo. Kana iri pasi pesimba rekunze, inoda kudzokera kumashure. Kana iri pakati pesimba rekunze nesimba rekubuda, inotanga kutenderera. Kana iri pamusoro pesimba rekunze, inodzoka kwairi.
| Planet | Kutenderera orbit speed pano | Escape speed pano |
|---|---|---|
| Earth | 7.61 km/s | 10.8 km/s |
| Moon | 1.62 km/s | 2.29 km/s |
| Mars | 3.42 km/s | 4.84 km/s |
