Ceev, ceev, thiab kev ceev yog txhua yam muaj feem xyuam nrog lub zog uas siv rau ntawm pob. Qhov siab dua koj kev ceev yog, lub zog ntau dua yuav muab tso rau hauv lub pob, zoo li hauv Newtons txoj cai thib ob, quab yuam sib npaug ntawm lub sijhawm loj kev ceev F = mas. Ceev- Ceev yog qhov tseem ceeb heev kom muaj nyob rau hauv ncaws pob.
Dhau li ntawm no, acceleration hauv ncaws pob yog dab tsi?
Kev nrawm . Kev nrawm yog ib feem tseem ceeb heev ntawm ncaws pob . Kev nrawm yog dab tsi pab players kom dhau lawv cov neeg sib tw sai sai.
