QUADRATIC RELATIONSHIP hauv PHYSICS . Quadratic kev sib raug zoo piav txog kev sib raug zoo ntawm ob qhov sib txawv sib txawv, ncaj qha lossis thim rov qab, thaum ib qho ntawm qhov sib txawv yog squared. Lo lus plaub fab piav txog ib yam dab tsi los yog hais txog lub hwj chim thib ob.

Ib yam li ntawd, nws raug nug, nws txhais li cas kom muaj kev sib raug zoo plaub ntug?

Quadratic kev sib raug zoo A quadratic kev sib raug zoo yog lej kev sib raug zoo nruab nrab ntawm ob qhov sib txawv uas ua raws li daim ntawv ntawm a plaub fab kev sib npaug. Txhawm rau muab nws yooj yim, qhov sib npaug uas tuav peb ob qhov sib txawv zoo li hauv qab no: Ntawm no, y thiab x yog peb qhov sib txawv, thiab a, b, thiab c yog qhov tsis tu ncua.

Qhov thib ob, dab tsi kev sib raug zoo muaj nyob rau hauv quadratic functions? Cov qauv ntawm a quadratic kev sib raug zoo ib txwm muaj ob tug ua tus exponent siab tshaj. Cov qauv yog ib txwm ntawm hom y = ax 2 + bx + c nrog a ≠ 0. b thiab c ua tau 0. Piv txwv li: y = 3 x 2 y = – 5 x 2 3 x – 4x.

Cov lus nug tseem yog, qhov kev sib raug zoo ncaj qha hauv physics yog dab tsi?

Kev Sib Raug Zoo : Qhov no yog qhov uas ob qhov sib txawv ua ib yam. Yog ib tug nce, lwm tus nce. Yog tias ib qho txo qis, qhov qis dua. Rov qab Kev sib raug zoo : Qhov no yog qhov uas ob qhov sib txawv ua qhov sib txawv. Yog tias ib qho nce ntxiv, qhov qis dua.

Kev sib raug zoo exponential yog dab tsi?

Exponential kev sib raug zoo yog kev sib raug zoo qhov twg ib qho ntawm cov hloov pauv yog ib qho exponent . Yog li es tsis txhob nws yog '2 multiplied by x', an kev sib raug zoo exponential tej zaum yuav muaj '2 tsa rau lub hwj chim x': Feem ntau yog thawj yam uas tib neeg ua kom nkag siab txog dab tsi kev sib raug zoo exponential zoo li yog kos ib daim duab.
