Amandla aphakathi ajikelezayo ngendlela efanayo - izinkinga nezixazululo

1. Ibhola elingu- 0.1 kg, elinamathiselwe ekugcineni kwentambo evundlile, lizungezwe yindilinga engu-radius engu- 50 cm kanti ijubane le-angle lebhola lingu- s 4 rad s ^-1 . Ubukhulu bamandla aphakathi nendawo buyini?

Kwaziwa:

Isisindo (m) = amagremu ayi-100 = 100/1000 kg = 1/10 kg = 0.1 kg

Isivinini se-angular ( ω) = 4 radians/se cond

Irediyasi (r) = 50 cm = 50/100 m = 0.5 m

Kufunwa: Amandla ase-Centripetal

Isixazululo:

Amandla ase-centripetal amandla aphelele akhiqiza ukusheshisa kwe-centripetal :

∑ F = ma _r

∑ F = mv ² /r = m ω ² r

∑ F = amandla aphelele = amandla ase-centripetal , m = isisindo , v = isivinini , ω = isivinini se-angular , r = irediyasi

∑ F = m ω ² r = (0.1)(4) ² (0.5) = (0.1)(16)(0,5) = 0.8 AmaNewton

2. Ibhola lijikeleza ngokulinganayo esiyingini esivundlile. Uma ijubane lishintsha libe yinani eliphindwe kane kunenani lokuqala, lingakanani ubukhulu bamandla aphakathi nendawo…..

Kwaziwa:

Isisindo = m

Isivinini = v

Isivinini sokuqala = v _o

Irediyasi (r) = r

Okufunwayo: Ubukhulu bamandla aphakathi nendawo

Isixazululo:

3. Ijika eligobile lerediyasi R lenzelwe ukuthi imoto ehamba ngesivinini esingu-12 ms ^–1 ikwazi ukujika ngokuphephile. I-coefficient yokungqubuzana okungaguquki phakathi kwemoto nomgwaqo = 0.4. Iyini irediyasi R. Ukusheshisa ngenxa yamandla adonsela phansi ( g ) = 10 ms ^–2.

Kwaziwa:

Isivinini (v) = 12 m/s

I-Coefficient yokungqubuzana okungaguquki ( μs ₎ = 0.4

Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s ²

Okufunwayo: Irediyasi (R)
