Linear Acceleration . Ib yam khoom uas txav mus rau hauv txoj kab ncaj nraim yog ceev yog tias nws qhov nrawm (qee zaus hu ua qhov nrawm) yog nce lossis txo qis rau lub sijhawm. Cov auto ua Kev nrawm hloov 60 MPH hauv 10 vib nas this. Yog li ntawd, nws kev ceev yog 60MPH/10s = +6 mi/hr/s.

Kuj paub, dab tsi yog linear acceleration?

Linear acceleration Qhov tseem ceeb yog ib txoj hauv kev los ntsuas qhov nrawm nrawm npaum li cas ntawm cov khoom hloov pauv. Koj nres ntawm lub teeb ci, ua ntej nrawm thiab txav mus rau qhov nrawm. Muaj kev hloov pauv yuav tsum tau mus ntawm qhov nrawm ntawm 0 mus rau qhov nce nrawm. Qhov kev hloov no hu ua kev ceev.

Qhov thib ob, lub cim rau acceleration yog dab tsi? Kev nrawm . Hauv Physics lossis Physics Science, kev ceev ( cim : a) txhais tau tias yog tus nqi hloov pauv (lossis derivative nrog rau lub sijhawm) ntawm kev tshaj tawm. Nws yog lisa vector kom muaj nuj nqis nrog qhov ntev / sijhawm². Hauv SI units, kev ceev yog ntsuas hauv meters/second² siv anaccelerometer.

Tsis tas li ntawd, acceleration hauv tsheb yog dab tsi?

Auto Channel. A tsheb acceleration iscalculated thaum lub tsheb tsis nyob rau hauv motion (0 mph), kom txog rau thaum lub sij hawm nws yuav siv sij hawm mus txog ib tug tshaj tawm ntawm 60 mais ib teev. Qhov no txhais tau hais tias qhov pib tshaj tawm yog xoom thiab qhov kawg velocityis 60 mais ib teev (26.82 meters ib ob).

Dab tsi yog acceleration?

Ib txwm acceleration . cov khoom ntawm kev ceev rau ib tug taw tes nyob rau hauv curvilinear tsab ntawv tsa suab uas yog qhia raws tus thawj xib fwb ib txwm mus rau lub trajectory mus rau qhov chaw ntawm curvature; ib txwm acceleration tseem hu ua centripetal kev ceev . Rau rectilinear motion lub ib txwm acceleration yog zero.
