Nws yuav siv lub Lub ntiaj teb kwv yees li 23 teev, 56 feeb thiab 4.09 vib nas this los ua ib qho kev hloov pauv tiav (360degrees). Qhov ntev ntawm lub sij hawm no yog hu ua ib hnub sidereal. Cov Lub ntiaj teb rotates ntawm ib nrab angular tshaj tawm 7.2921159 × 105radians/thib ob.

Tom qab ntawd, dab tsi yog tus qauv rau angular tshaj tawm?

Kom tau txais peb qhov thib ob formula rau angular tshaj tawm , peb lees paub tias theta yog muab rau hauv radians, thiab lub ntsiab lus ntawm radian ntsuas muab theta = s / r. Yog li, peb tuaj yeem ntsaws theta = s / rinto peb thawj angular velocity formula . Qhov no muab w = (s / r) / t.

Qhov thib ob, lub angular momentum ntawm lub ntiaj teb yog dab tsi? Qhov nruab nrab angular zog yog mvr, kho cov Lub ntiaj teb zoo li nws yog point mass. Lub ntiaj teb siv 365 hnub mus rau ib lub voj voog ua tiav nyob ib ncig ntawm Sun. Tsis muaj lub npe tshwj xeeb rau kev sib xyaw ua ke ntawm cov units. Kev taw qhia ntawm vector isperpendicular rau lub orbit.

Ntawm no, koj txhais li cas los ntawm angular tshaj tawm?

Angular tshaj tawm yog cov tus nqi ceev uas ib yam khoom los yog ib tug particle yog rotating ib puag ncig los yog aspecific point nyob rau hauv ib lub sij hawm. Nws tseem hu ua rotational ceev . Angular tshaj tawm yog ntsuas inangle per unit time or radians per second (rad/s).

Dab tsi yog tus qauv rau angular tshaj tawm hauv physics?

Angular Velocity yog ib qho kev ntsuas sai npaum li cas anobject txav los ntawm lub kaum sab xis. Nws yog qhov hloov ntawm lub kaum sab xis ntawm cov khoom txav txav (ntsuas hauv radians), muab faib los ntawm lub sijhawm. Angularvelocity muaj qhov loj (tus nqi) thiab kev taw qhia. Lub sijhawm nws siv rau ob txhais tes kom txav mus los ntawm 180 degrees yog 30 vib nas this, yog li t = 30 s.
