Kev sib txhuam yog qhov kev tawm tsam ntawm ib qho khoom txav mus rau lwm qhov. Nws tsis yog lub zog tseem ceeb, zoo li lub ntiajteb txawj nqus lossis electromagnetism. Hloov chaw, cov kws tshawb fawb ntseeg tias nws yog qhov tshwm sim ntawm electromagnetic attraction ntawm cov khoom siv hauv ob qhov chaw kov.

Tsis tas li ntawd, kev sib txhuam thiab hom kev sib txhuam yog dab tsi?

Kev sib txhuam yog lub zog uas tawm tsam kev txav ntawm txhua qhov chaw uas muaj kev sib cuag. Muaj plaub hom kev sib txhuam : zoo li qub, zawv zawg, dov, thiab kua dej kev sib txhuam . Static, zawv zawg, thiab dov kev sib txhuam tshwm sim nruab nrab ntawm cov khoom siv. Kua dej kev sib txhuam tshwm sim hauv cov kua thiab roj.

Tsis tas li ntawd, dab tsi ua rau kev sib txhuam? Ua rau ntawm Kev sib txhuam . Kev sib txhuam yog lub zog uas tiv thaiv qhov kev sib txheeb ntawm ob yam khoom lossis cov khoom siv. Cov ua rau Lub zog tiv thaiv no yog molecular adhesion, nto roughness, thiab deformations. Adhesion yog lub zog molecular uas tshwm sim thaum ob cov ntaub ntawv raug coj mus rau hauv kev sib cuag nrog ib leeg.

Kuj paub, kev sib txhuam thiab piv txwv yog dab tsi?

Ib phau ntawv txav hla lub rooj yog ib qho piv txwv ntawm zawv zawg kev sib txhuam . Ib yam khoom hnyav exerts siab dua ntawm qhov chaw nws swb, yog li qhov zawv zawg kev sib txhuam yuav loj dua. Cua, dej thiab roj yog tag nrho cov kua. Cua kuj yog ib hom kua kev sib txhuam . Raws li ib qho khoom ntog, huab cua tsis kam thawb rau ntawm qhov khoom.

Kev sib txhuam yooj yim txhais yog dab tsi?

Kev sib txhuam yog lub zog uas tuav rov qab qhov kev txav ntawm cov khoom zawv zawg. Qhov ntawd yog nws. Kev sib txhuam tsuas yog qhov ntawd yooj yim . Koj yuav pom kev sib txhuam txhua qhov chaw uas cov khoom sib cuag nrog ib leeg. Cov quab yuam ua nyob rau hauv qhov opposite direction mus rau txoj kev ib yam khoom xav swb.
