Qhov tseeb, qhov nrawm hloov pauv tas li - 10 m / s - hauv txhua ob lub sijhawm. Txhua lub sijhawm khoom nrawm hloov pauv, cov khoom raug hais kom nrawm; nws muaj acceleration.
Yuav ua li cas koj pom lub sijhawm nrawm ntawm ib qho khoom?
Koj pom qhov nrawm nrawm li cas?
- Ua haujlwm tawm qhov kev hloov nrawm rau koj lub sijhawm.
- Xaiv qhov hloov pauv ntawm lub sijhawm rau lub sijhawm koj tab tom txiav txim siab.
- Sib faib qhov hloov nrawm los ntawm kev hloov pauv hauv lub sijhawm.
- Qhov tshwm sim yog qhov nruab nrab nrawm rau lub sijhawm ntawd.
Lub sijhawm lub sijhawm twg qhov khoom puas muaj xoom acceleration?
Txhua lub sijhawm qhov nrawm yog qhov tsis tu ncua, qhov nrawm yog xoom.
Thaum ib qho khoom nyob ntawm so yog acceleration?
Yog tias peb xav txog qhov teeb meem sai, nws yuav zoo li qhov nrawm yuav tsum yog zero. Nyob rau ib pliag, peb tsis txav, thiab ib lub sij hawm me me tom qab peb tseem tsis tau tsiv, yog li tsis muaj kev hloov ceev. Yog li ntawd, qhov acceleration yuav tsum yog xoom.
Yuav ua li cas nrawm rau lub sijhawm?
Acceleration-Time Graph yog dab tsi? Acceleration-Time Graph qhia lub acceleration plotted tiv thaiv lub sij hawm rau a particle tsiv nyob rau hauv ib tug ncaj kab. Lub acceleration-time plots acceleration values on the y-axis and time values on the x-axis.
