Xav tawm tsam txoj cai ntawm physics-lossis tsawg kawg yog dag lwm tus xav tias koj tau ua? Txhua yam koj yuav xav tau yog qee yam tais diav noj hmo thiab muaj tswv yim me ntsis. Nrog rau cov cuab yeej no, nws yooj yim los ua cov tais diav uas zoo ib yam tshwm rau hauv qhov chaw ntawm ntug iav.
Cov kauj ruam
Kauj Ruam 1. Tau khob iav loj
Nws yog qhov tshwj xeeb tshaj yog tias iav muaj lub qhov ncauj dav nrog lub hauv qab kaw.
Kauj Ruam 2. Sau lub khob tsawg kawg ib nrab ntawm cov kua
Nco ntsoov tias tag nrho qhov hnyav ntawm cov nyiaj yuav tau txais kev txhawb nqa ntawm ib qho taw tes nyob rau sab ntug ntawm lub khob. Khaws qhov no hauv siab thiab xyuas kom lub hauv paus ntawm iav ruaj khov txaus kom txhawb nqa qhov hnyav.
Kauj Ruam 3. Nqa rab diav rawg thiab diav ua ke
Muab ob sab tines ntawm rab diav rawg hla tom qab lub diav Thaum lawv sib txuas, cov tais diav yuav tsum ua kom zoo li cov duab boomerang.
Kauj Ruam 4. Tau txais tus pas nrig los yog tus pas txhuam hniav, thiab muab nws tso nruab nrab ntawm rab diav rawg nruab nrab
Xyuas kom tseeb tias nws tseem tab tom kov lub diav. Tawm ntau npaum li cov khoom sib tw ua rau nruab nrab ntawm "boomerang" cov duab zoo li ua tau.
Kauj Ruam 5. Muab lub cuab yeej ua tiav
Nqa tag nrho cov khoom siv thiab (ntawm no los ua qhov tsis yooj yim) sib npaug ntawm cov khoom sib dhos ntawm ntug iav nrog ob lub qhov xaus xaus taw tes rov qab rau iav. Nco ntsoov tias tus pas nrig yuav yog kab rov tav.
Kauj Ruam 6. Tshuav cov cuab yeej siv
Nws yuav siv sijhawm koj los txiav txim qhov twg los tso tus cim sib dhos. Sim txav nws ntawm ib sab mus rau ib sab, ntxiv rau kom ze dua thiab nyob deb dua ntawm iav, txhawm rau nrhiav qhov chaw zoo tshaj plaws.
Kauj Ruam 7. Xav txog qhov hlawv qhov kawg ntawm cov cim sib dhos tawm tom qab koj tau sib npaug txhua yam (xaiv tau)
Tom qab ntawd zaum rov qab thiab sau koj cov thawj koom ruam. Qhov laj thawj uas tib neeg ntseeg tias nws tab tom tawm tsam lub ntiajteb txawj nqus yog qhov tseeb uas lawv ntseeg tias nws sib npaug sib npaug rau tag nrho lub khob, tsis yog ib sab ntawm nws. Lawv yog, thev naus laus zis, dag lawv tus kheej.
Lub tswv yim
- Lub ntsej muag lub ntsej muag lub ntsej muag zoo tshaj rau ib puag ncig rau qhov ua kom yuam kev no, vim tias puag ncig ib puag ncig muaj qhov nyiam ua kom ntau ntau thaum koj tab tom sim ua kom sib npaug ntawm cov cuab yeej.
- Lwm txoj hauv kev yog siv ob rab diav rawg thiab muab peb lub hlis twg (lossis lwm qhov nyiaj npib nruab nrab) nruab nrab ntawm qhov nruab nrab ntawm ob rab rawg thaum lawv tuav ua ke thiab sib npaug qhov no ib yam.
- Tseem muaj lwm txoj hauv kev: Tsim rab diav rawg thiab rab diav "boomerang" nrog rau ib lub matchstick ua ntej. Khaws lwm tus pas nrig ncaj rau saum cov hnyav ntsev shaker. Sib npaug ntawm ib tus pas nrig ntawm lwm qhov. Yog tias koj muaj hmoo, qhov nruab nrab ntawm lub ntiajteb txawj nqus yuav ua haujlwm kom tso cai rau koj kom sib npaug ntawm qhov sib tw ntawm ib qho ntawm lwm qhov ze ntawm 90-degree lub kaum ntse ntse. Qhov no yuav siv me ntsis ntawm kev sim.
- Koj tuaj yeem teeb hluav taws rau ob qho kawg ntawm tus pas nrig tom qab koj tau sib npaug lawv thiab lawv yuav kub hnyiab mus rau qhov chaw uas lawv tab tom kov iav thiab cov nyiaj; qhov no yuav tsav tsheb mus tsev tiag qhov tseeb tias nws zoo li txias cia li dai rau hauv nruab nrab cua.
- Nco ntsoov tias tus neeg tab tom ntsib lub khob los ntawm sab xis, lossis lwm tus lawv yuav pom tias nws ua haujlwm li cas.
- Qhov nyuaj tshaj plaws ntawm qhov ua kom yuam kev yog qhov ua kom raug. Qee rab diav rawg thiab rab diav yuav tsis koom tes, yog li sim nws hauv tsev nrog koj tus kheej cov nyiaj los yog ua nws ntawm lub tsev noj mov uas koj mus ntsib ntau zaus los saib seb lawv puas yuav ua haujlwm ib yam.
Lus ceeb toom
- Tsis txhob sim hlawv cov pas nrig ntawm cov dej haus uas muaj cawv.
- Yog tias koj txiav txim siab teeb hluav taws rau tus pas ntsuas kub, ceev faj kom tsuas yog hlawv qhov kawg ntawm tus pas nrig, tsis yog qhov nruab nrab pom tseeb. Nws pab thaum hlawv cov pas nrig kom muaj ntau cov khoom sib dhos kom hlawv.
