Kuj paub, tus qauv rau kev ncua deb hauv science yog dab tsi?

Txhawm rau daws qhov kev ncua deb siv tus qauv rau kev ncua deb d = st, lossis nrug sib npaug ceev sij hawm. Rate thiab ceev zoo sib xws vim lawv ob leeg sawv cev rau qee qhov kev ncua sij hawm ib chav tsev xws li mais tauj ib teev lossis kilometers ib teev. Yog tus nqi r yog tib yam li ceev s, r = s = d/t.

Tsis tas li ntawd, koj yuav xam qhov deb li cas? Cov hauj lwm ntawm cov lus nyob rau hauv daim duab peb sab qhia qhov twg lawv yuav tsum tau mus rau hauv qhov sib npaug.
