Piav: Lub Kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm −12 m yog 12 meters. Qhov deb ntawm lub keeb kwm mus rau qhov siab tshaj plaws txoj hauj lwm hu ua tshem tawm ntawm ib yam khoom . Qhov siab tshaj plaws hloov chaw ntawm cov particle nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov chaw hu ua trough.

Ib yam li ntawd, qhov piv txwv ntawm kev txav chaw yog dab tsi?

Yog hais tias ib yam khoom txav mus rau ib qho kev siv ncej-rau piv txwv , yog tias tus xibfwb txav mus rau sab xis ntawm lub rooj tsavxwm, lossis tus neeg caij tsheb txav mus rau tom qab ntawm lub dav hlau - ces qhov khoom qhov chaw hloov. Qhov kev hloov hauv txoj haujlwm no yog hu ua hloov chaw.

Tsis tas li ntawd, koj yuav nrhiav tau qhov kev hloov ntawm ib yam khoom li cas? Rau xam kev khiav tawm , tsuas yog kos ib vector los ntawm koj qhov chaw pib mus rau koj txoj haujlwm kawg thiab daws qhov ntev ntawm kab no. Yog tias koj txoj haujlwm pib thiab xaus yog tib yam, zoo li koj txoj kev ncig 5K, ces koj hloov chaw yog 0. Nyob rau hauv physics, hloov chaw yog sawv cev los ntawm Δs.

Hauv qhov no, qhov kev ncua deb yog qhov hloov ntawm txoj haujlwm?

Nyob deb yog ib qho scalar ntau uas hais txog "ntau npaum li cas hauv av ib yam khoom tau npog" thaum nws txav. Displacement yog ib tug vector kom muaj nuj nqis uas yog hais txog "yuav deb npaum li cas ntawm qhov chaw ib yam khoom yog"; nws yog qhov khoom tag nrho hloov txoj hauj lwm.

Qhov kev tshem tawm yog dab tsi?

A hloov chaw yog ib tug vector uas nws ntev yog qhov luv tshaj nyob deb ntawm qhov pib mus rau qhov kawg txoj hauj lwm ntawm ib tug taw tes P. Nws quantifies ob qhov deb thiab kev taw qhia ntawm ib tug xav txog tej yam nyob rau hauv ib tug ncaj kab los ntawm thawj txoj hauj lwm mus rau qhov kawg txoj hauj lwm ntawm lub point.
