Txhua zaus lub zog hloov pauv, qee lub zog khiav tawm raws li cua sov. Nws tshwm sim thaum koj tig rau hluav taws xob los teeb lub teeb. Lub teeb teeb muab hluav taws xob tawm thaum lub zog hluav taws xob yog hloov mus rau lub teeb lub zog. Bill Nye's "Energy" ntu yuav tiag tiag khaws koj tsiv.

Tsuas yog li ntawd, vim li cas ho tsis lub pob balling pendulum ntaus Bill Nye ntawm lub ntsej muag?

Vim tias lub zog kinetic yuav tsis muaj ntau dua li lub zog muaj peev xwm. Qhov no yog ua tiav thaum lub zog (lub laub lossis rub) ua rau qee yam nyob deb.

Tsis tas li ntawd, dab tsi tshwm sim txhua lub sijhawm hloov pauv lub zog? Zog ua tau hloov cov ntawv . Txhua lub sij hawm lub zog hloov daim ntawv , ib co zog khiav raws li cua sov. Nws tshwm sim thaum koj qhib hluav taws xob los teeb lub teeb. Lub teeb hluav taws xob muab hluav taws xob tawm thaum hluav taws xob zog hloov mus rau hauv lub teeb zog.

Ua kom pom qhov no, Heat Bill Nye yog dab tsi?

Bill Nye's scientific lecture yog hais txog kub . Nws ntws yog lub zog ntawm txav molecules. Kub tuaj yeem ua rau txhua yam mus thiab kub hnyiab tau ntev li ntev tau nws muaj cov convection, conduction thiab hluav taws xob.

Dab tsi yog 3 hom ntawm lub zog uas hluav taws xob hluav taws xob tuaj yeem hloov mus rau hauv?

Hluav taws xob muaj peev xwm hloov mus rau mechanical zog , lub teeb zog , kub zog , thiab lwm yam tshuaj zog tau hloov dua siab tshiab rau hluav taws xob zog . Kub zog tau hloov mus rau cua sov zog.
