Contrast rau lub gravitational zog (nws zog pib ntawm qhov chaw ntawm qhov khoom)-tus normal zog pib ntawm qhov chaw. Cov normal zog tshwm sim los ntawm electromagnetic zog ; tshwj xeeb, theelectrons hauv phau ntawv thawb tawm tsam cov electrons hauv lub rooj.

Ib yam li ntawd, nws yog nug, dab tsi txhais tau tias nyob rau hauv ib txwm quab yuam?

Hauv mechanics, lub normal force yog ib feem ntawm kev sib cuag zog uas yog perpendicular rau saum npoo uas cov khoom tiv tauj.

Kuj Paub, dab tsi yog ib txwm quab yuam hauv kev sib txhuam? Cov normal zog yog ib feem ntawm kev sib cuag zog nruab nrab ntawm ob yam khoom, ua perpendicular rau lawv cov interface. Cov kev sib txhuam quab yuam yog lwm yam khoom; itis nyob rau hauv ib qho kev taw qhia parallel mus rau lub dav hlau ntawm lub interface ntawm cov khoom. Kev sib txhuam ib txwm ua los tawm tsam ib qho kev txheeb ze ntawm qhov chaw.

Tsis tas li ntawd, koj piav li cas lub zog ib txwm muaj?

Cov normal zog yog cov zog uassurfaces exert los tiv thaiv cov khoom los ntawm ib leeg. Lub zog qub yog kev sib cuag zog . Yog tias ob qhov chaw tsis nyob hauv kev sib cuag, lawv tsis tuaj yeem ua haujlwm normal zog ntawm ib leeg.

Koj nrhiav tau lub zog li cas?

Cov mis rau zog hais zog yog equalto mass (m) multiplied by acceleration (a). Yog tias koj muaj ob qho ntawm peb qhov sib txawv, koj tuaj yeem daws qhov thib peb. quab yuam ntsuas hauv Newtons (N), qhov hnyav hauv kilograms (kg), thiab accelerationin meters ib ob squared (m / s2).
