Cov kws tshaj lij los ntawm University of Leicester (UK), siv cov cai lij choj ntawm aerodynamics, suav qhov ceev ntawm lub protagonist ntawm comics thiab zaj duab xis, Batman. Txog kev suav, lawv tau tshuaj xyuas ib ntu ntawm K. Nolan zaj yeeb yaj kiab "Inception" (2005), qhov chaw uas tus puav-txiv neej, pom nws lub tsho ntev, ya tawm ntawm lub skyscraper.
Tom qab kuaj xyuas ntu ntawm Batman lub davhlau los ntawm lub tsev siab, cov kws tshawb fawb yav tom ntej David Marshall thiab nws cov phooj ywg los ntawm Cov Kws Tshaj Lijxij ntawm Physics thiab Astronomy tau suav txog qhov loj ntawm cov rog ua rau ib tus neeg thaum lub davhlau ntawd. Qhov muab xam tau raws qhov xwm txheej qhov hnyav ntawm lub superhero ntawm 90 kilo, qhov siab ntawm lub tsev - 150 meters. Cov tub ntxhais kawm Physics kuj suav qhov ntau ntawm Batman ntawm lub dhaus taw tshwj xeeb. Thaum no Cape ntsib qhov khiav ntawm huab cua, nws ncaj thiab ua tsis yeem, thaum nws qhov dav yog 4.7 m.
Txhua qhov kev suav tau ua tiav raws li cov cai ntawm aerodynamics. Raws li cov ntaub ntawv tau txais, cov tub ntxhais kawm xaus lus tias lub zog nqa ntawm lub duav - cape yuav txaus kom Batman nyob rau hauv huab cua, thaum superhero lub davhlau ceev yuav yog los ntawm 60 txog 100 km ib teev.
Raws li cov kev xav paub no, thaum dhia tawm los ntawm lub tsev 150 meters siab, tus txiv neej ntaus yuav ya 350 meters hauv peb vib nas this, thaum nws qhov siab tshaj plaws yuav yog 109 km ib teev, thiab nws qhov tsaws ceev yog 80 km toj ib teev. Tom qab ua tiav tag nrho cov kev suav, cov kws tshawb fawb cov tub ntxhais hluas tau xaus lus tias Batman tuaj yeem ya nrog nws lub plhaw, tab sis kev tsaws ntaj yuav muaj kev phom sij vim muaj kev kub ntxhov nyob hauv vib nas this kawg ntawm lub davhlau - tus superhero yuav yooj yim sib tsoo hauv av.
Raws li ib qho ntawm cov kws sau ntawv ntawm cov kev suav hais tias: "Yog tias Batman xav muaj sia nyob tom qab lub davhlau zoo li no, nws yuav tsum xav tau lub npog loj dua." Cov kws txawj lub cev kuj tau qhia cov kws ua yeeb yaj kiab kom tawm los nrog cov dav hlau thawb kom txuas ntxiv cov huab cua nrawm thiab qeeb qeeb tsaws yog tias lawv xav ua kom loj me me ntawm Batman lub cape tsis hloov.
Daim ntawv no los ntawm plaub tus tub ntxhais kawm physics, lub npe hu ua "Trajectory of a Falling Batman", tau luam tawm thaum lub Kaum Ob Hlis 2011 nyob rau hauv phau ntawv Journal ntawm Physics Tshwj Xeeb Cov Ntsiab Lus thiab tsim cov kev sib xyaw los ntawm cov pej xeem.
