Thaum peb ncaws lub pob , lub zog peb siv rau nws ua rau nws ceev los ntawm ib tug ceev ntawm 0 mus rau ib tug ceev ntawm kaum ob kilometers ib teev. Thaum lub pob tso tawm ntawm ko taw, nws pib decelerate (tsis zoo kev ceev ) vim yog lub zog ntawm kev sib txhuam uas tau ua rau nws (raws li peb tau pom hauv qhov piv txwv dhau los).
Yog li ntawd, qhov acceleration ntawm pob ncaws pob yog dab tsi?
Physics ntawm ncaws pob a ncaws pob . Cov ncaws pob accelerates thaum koj ncaws lub pob . * Qhov nruab nrab kev ceev thaum ncaws a ncaws pob a pob yog hais txog 8 meters ib sec.
Tsis tas li ntawd, Newton txoj cai thib ob siv rau kev ncaws pob li cas? Cov ob txoj cai ntawm tsab ntawv tsa suab hais tias quab yuam ntawm ib yam khoom yog sib npaug rau qhov loj ntawm cov khoom sib npaug los ntawm nws qhov acceleration. Yog peb thov qhov no txoj cai rau kev ncaws pob, nws qhia peb tias qhov nyiaj uas lub pob nrawm nrawm yog nyob ntawm lub zog siv los ntawm lub quarterback thiab qhov loj ntawm lub pob.
Ntxiv mus, pes tsawg lub zog ntawm tus neeg ncaws pob nruab nrab siv los ncaws pob?
Yog li thaum cov kws tshaj lij xa cov pob ntawm 30 meters ib ob thiab 1,200 hli ntawm kev quab yuam, tus neeg laus neeg laus nruab nrab xa pob ntawm ib ncig ntawm 25 meters ib ob raws li kev ncaws pob 1,000 phaus ntawm kev quab yuam, thaum nruab nrab cov tub ntxhais hluas ncaws pob tsuas tuaj yeem khaws lub pob nrawm ntawm 14.9 meters ib ob, qhia tsuas yog 600 phaus.
Puas yog ncaws pob lub peev xwm lossis lub zog kinetic?
Qhov no zog feem ntau pom thaum lub ncaws pob hauv huab cua. Nws yog hu ua muaj peev xwm zog vim nws muaj peev xwm ua hauj lwm. Yog ncaws pob pob yog nce mus rau ib qho siab, nyob rau sab saum toj, ua ntej nws nce Kinetic Zog , nws muaj Muaj peev xwm khaws cia tias nws yuav siv thaum nws pib txav mus los.

Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo

Nws siv zog npaum li cas los ncaws pob ncaws pob?
Yog li thaum cov kws tshaj lij xa cov pob ntawm 30 meters ib ob thiab 1,200 phaus ntawm lub zog, tus neeg laus nruab nrab xa pob ntawm ib ncig ntawm 25 meters ib ob raws li kev ncaws pob ntawm 1,000 phaus ntawm lub zog, thaum cov tub ntxhais hluas nruab nrab tsuas tuaj yeem sau lub pob. ceev ntawm 14.9 meters ib ob, qhia tsuas yog 600 phaus
Puas yog lub sijhawm qeeb thaum koj mus txog qhov nrawm ntawm lub teeb?
Einstein txoj kev xav ntawm kev sib raug zoo tshwj xeeb hais tias lub sijhawm qeeb lossis nrawm dua nyob ntawm seb koj tsiv mus li cas txheeb ze rau lwm yam. Mus txog qhov ceev ntawm lub teeb, ib tug neeg nyob rau hauv lub spaceship yuav muaj hnub nyoog qeeb dua nws ntxaib nyob rau hauv tsev. Tsis tas li ntawd, raws li Einstein txoj kev xav ntawm kev sib raug zoo, lub ntiajteb txawj nqus tuaj yeem khoov lub sijhawm
