Yog tias daim duab yog nrawm vs lub sijhawm, tom qab ntawd nrhiav thaj chaw yuav muab koj hloov chaw, vim nrawm = hloov chaw / sijhawm. Yog tias daim duab yog kev ceev vs sij hawm, ces nrhiav qhov chaw muab rau koj hloov hauv nrawm , vim kev ceev = hloov hauv nrawm / sijhawm.

Ua raws li qhov no hauv kev xav, ua li cas koj pom qhov nrawm ntawm acceleration?

Siv tus qauv los nrhiav kev ceev . Ua ntej sau koj qhov sib npaug thiab tag nrho cov kev hloov pauv tau muab. Qhov sib npaug yog a = Δv / Δt = (vf -vi)/(tf -ti). Tshem tawm qhov pib nrawm los ntawm qhov kawg nrawm , ces faib qhov tshwm sim los ntawm lub sij hawm luv luv. Qhov kawg tshwm sim yog koj qhov nruab nrab kev ceev dhau lub sijhawm ntawd.

Ib yam li ntawd, qhov kev tshaj tawm tsis zoo txhais li cas? Kom paub qhov txawv ntawm ob qho kev qhia hauv nrawm , koj ua tau muaj qhov zoo thiab a tsis zoo vectors: vectors uas taw tes nyob rau hauv opposite direction. Yog li ntawd, a negative velocity txhais tau tias tias qhov taw qhia ntawd nrawm yog opposite rau lwm tus nrawm (nrog tus nqi zoo).

Hais txog qhov no, tus qauv ntawm kev tshaj tawm yog dab tsi?

Velocity Formula . Cov nrawm yog lub sij hawm tus nqi hloov pauv. Yog tias 'S' yog qhov hloov chaw ntawm ib qho khoom hauv qee lub sijhawm 'T', ces qhov nrawm yog sib npaug, v = S/T. Cov units ntawm nrawm yog m/s los yog km/hr.

Yuav ua li cas acceleration zoo li ntawm ib daim duab?

Thaum twg kev ceev yog tas li , cov kev ceev -lub sij hawm nkhaus yog kab rov tav. Tus nqi hloov ntawm kev ceev nrog lub sij hawm yog ib qho tsis muaj nuj nqis kom muaj nqes ntawm txoj kab nkhaus ntawm qhov no daim duab kuj tsis muaj qab hau. Thaum ob lub nkhaus sib npaug, ob qho khoom muaj tib yam kev ceev thaum ntawd.
