Raws li lub npe qhov sib txawv ntawm mechanics thiab kinematics
yog tias mechanics yog (physics) ceg ntawm physics uas cuam tshuam nrog kev ua ntawm lub zog ntawm cov khoom siv nrog loj thaum kinematics yog (physics) ceg ntawm mechanics kev txhawj xeeb nrog cov khoom hauv kev txav, tab sis tsis nrog cov rog koom nrog.
Ib yam li ntawd, tib neeg nug, yog kinematics ib feem ntawm mechanics?
Kinematics yog ceg ntawm classical mechanics uas piav qhia txog kev txav ntawm cov ntsiab lus, cov khoom thiab cov txheej txheem ntawm pawg ntawm cov khoom, yam tsis muaj kev siv rau qhov ua rau ntawm kev txav (piv txwv li, quab yuam). Kev kawm ntawm kinematics feem ntau hu ua "geometry of motion." Cov khoom nyob hauv kev txav mus los thoob plaws peb.
Ib yam li ntawd, kinematics piv txwv yog dab tsi? Kinematics . Kinematics yog kev kawm ntawm cov khoom nyob rau hauv kev txav, muaj tshaj tawm, acceleration thiab momentum. Piv txwv : Tsheb ciav hlau tsiv, txav dej hauv tus dej.
Tsis tas li ntawd, koj txhais li cas los ntawm kinematics thiab kinetics?
" Kinetics : Kev kawm ntawm cov quab yuam uas ua rau muaj zog (ex. torque, gravity, kev sib txhuam, thiab lwm yam) thiab ua tau muab faib ua ob pawg; Linear thiab angular motion. Kinematics : Txoj kev kawm piav qhia txog kev txav mus los (xws li kev txav chaw, sijhawm, nrawm, thiab lwm yam)"
Kinematics siv li cas hauv lub neej tiag tiag?
Cia kuv hais, qee qhov piv txwv zoo li: Nws yog siv nyob rau hauv lub dav hlau ya, bowling thiab ntaus hauv kab civliv, txiav txim siab ceev, nrawm nrawm ntawm txhua yam khoom txav lossis quab yuam ua rau lub cev thiab. Physics daws teeb meem thiab kinematics cuam tshuam nrog feem ntau ntawm cov teeb meem daws teeb meem hauv Physics.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm classical mechanics thiab quantum mechanics?
Nyob rau hauv luv luv, lub ntsiab sib txawv ntawm quantum thiab classical physics yog qhov txawv ntawm ib tug rampand ib staircase. Nyob rau hauv classical mechanics, cov xwm txheej (feem ntau) yog tas mus li, uas yog hais tias lawv txav mus rau hauv tus qauv, muaj kev sib haum xeeb thiab ua tau zoo. Qhov projectile motion yog ib qho piv txwv zoo ntawm classical mechanics
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
