Kuchuluka ndi mayunitsi a fizikisi - mavuto ndi mayankho

1.

Chigawo chapadziko lonse cholondola chomwe chawonetsedwa ndi wophunzira…

A. R ndi S

B. P ndi R

C. P ndi Q

D. Q ndi S

Anakonza

Wophunzira P:

Chigawo cha kutalika cha mayiko onse ndi mita (m), osati sentimita (cm)

Chida choyezera kutalika ndi wolamulira.

Q Wophunzira:

Gawo lamagetsi lapadziko lonse lapansi ndi Ampere (A)

Chida choyezera mphamvu yamagetsi ndi Ampere mita.

Wophunzira R:

Chigawo cha kutentha chapadziko lonse lapansi ndi Kelvin (K)

Chida choyezera kutentha ndi thermometer, osati hydrometer.

Hydrometer ndi chida chomwe chimagwiritsidwa ntchito poyesa kuchuluka kwa madzi kutengera lingaliro la kuyandama.

Wophunzira S:

Chigawo chapadziko lonse lapansi (SI) cha kulemera ndi kilogalamu (Kg)

Chida choyezera kulemera ndi sikelo yoyezera

Deta yolondola komanso yochokera ku gawo la SI (International Unit) lomwe lawonetsedwa ndi ophunzira Q ndi S.

Yankho lolondola ndi D.

2. Pezani ubale wolondola pakati pa kuchuluka ndi mayunitsi.

Anakonza

Mphamvu = Kulemera x Kuthamanga

Chigawo cha kulemera chapadziko lonse lapansi ndi kilogalamu (kg)

Gawo lapadziko lonse la kufulumizitsa ndi mamita pa sekondi imodzi (m/s ² )

Chigawo cha mphamvu = kg m/s ² = kg ms ^-2

Kupanikizika = mphamvu / dera

Chigawo cha mphamvu yapadziko lonse lapansi ndi kg m/s ²

Gawo lapadziko lonse lapansi la dera ndi ^m2

Chigawo cha kupanikizika = kg /ms ² = kg m ^-1 s ^-2

Mphamvu = Ntchito

Ntchito = mphamvu x kusamuka

Chigawo cha mphamvu yapadziko lonse lapansi ndi kilogalamu mita pa sekondi imodzi, sikweya (kg m/s ² )

Gawo lapadziko lonse la kusamuka ndi mita (m)

Gawo la mphamvu = gawo la ntchito = kg m ² /s ² = kg m ² s ^-2

Mphamvu = Ntchito / nthawi

Gawo la ntchito yapadziko lonse lapansi ndi kilogalamu mita imodzi yozungulira pa sekondi imodzi yozungulira (kg m ² /s ² )

Gawo la nthawi yapadziko lonse lapansi ndi lachiwiri (s)

Chigawo cha mphamvu ndi kg m ² /s ³ = kg m ² s ^-3

Yankho lolondola ndi D.

3.

Kutengera ndi tebulo lomwe lili pamwambapa, pezani A, B, C, D, ndi E.

A. Voliyumu, kilogalamu, kutentha, dera, mita

B. Kutalika, kilogalamu, nthawi, dera, Newton

C. Kutalika, kilogalamu, voliyumu, dera, Joule

D. Kutalika, Newton, nthawi, voliyumu, mita

Yankho:

A = Utali

B = Kilogalamu

C = Nthawi

D = Chigawo

E = Kg m/s ² = Newton

Yankho lolondola ndi B.

4. Dziwani mitundu iwiri ya zinthu zofunika ndi mayunitsi mu Dongosolo Lapadziko Lonse.

A. Kutalika– mita, kulemera – kg ndi chaji yamagetsi—coulomb

B. Nthawi – yachiwiri, kutentha – Kelvin, mphamvu yowala—Candela

C. Chachiwiri – nthawi, mita – kutalika, kg—kulemera

D. kulemera – kg, nthawi – sekondi, Kelvin – kutentha

Anakonza

Kuchuluka koyambira ndi mayunitsi apadziko lonse lapansi (SI):

Kutalika – mita (m)

Kulemera – kilogalamu (kg)

Nthawi - sekondi (masekondi)

Kutentha – Kelvin (K)

Kuwala kwamphamvu—Candela

Yankho lolondola ndi B.

5.

Kuchuluka koyenera ndi mayunitsi kutengera International System of Units (SI) komwe kwawonetsedwa ndi nambala…

A. 1 ndi 3

B. 1 ndi 4

C. 1, 2, ndi 3

D. 1, 3, ndi 4

Anakonza

Kuchuluka ndi mayunitsi a Dongosolo Lapadziko Lonse (SI):

(1) Kutentha - Kelvin

(2) Kulemera - Kilogalamu

(3) Nthawi - Yachiwiri

(4) Utali - Meter

Yankho lolondola ndi D.
