Izinkinga Ezixazululiwe ku-Basic Physics

3 Izinkinga nezixazululo mayelana ne-Moment of inertia equation

1. Isilinda esiqinile sinobubanzi obungu-8 cm kanye nesisindo esingu-2 kg. Okwamanje, ibhola eliqinile linobubanzi obungu-5 cm kanye nesisindo esingu-4 kg. Uma izinto ezimbili zijikeleza nge-axis phakathi nendawo yazo, nquma isilinganiso sesikhathi sokungapheleli kwesilinda kanye nebhola.

Kwaziwa:

Irediyasi yesilinda eqinile (r) = 8 cm = 0.08 m

Isisindo sesilinda esiqinile (m) = 2 kg

Irediyasi yebhola eqinile (r) = 5 cm = 0.05 m

Isisindo sebhola eliqinile (m) = 4 kg

Okufunwayo: Ukuqhathaniswa kwesikhathi sokungahlali kahle kwesilinda nebhola

Izinkinga nezixazululo ezi-3 mayelana ne-Momentum equation

1. Uma ijubane lento liba ngokuphindwe kahlanu ijubane layo lokuqala, khona-ke umfutho wento uba ….. umfutho wayo wokuqala.

Kwaziwa:

Isivinini sokuqala = v

Isivinini sokugcina = 5v

Isisindo = 1

Okufunwayo: Umfutho

Izinkinga nezixazululo ezi-3 mayelana ne-Speed ​​equation

1. Imoto iya eningizimu ibanga elingamamitha ayi-100 ngomzuzu owodwa bese ijika iye empumalanga ibanga elingamamitha ayi-120 ngemizuzu engu-0.5. Nquma isivinini esimaphakathi semoto.

Kwaziwa:

Ibanga eliphelele = amamitha ayi-100 + amamitha ayi-120 = amamitha angama-220

Isikhathi esiphelele = umzuzu o-1 + imizuzu engu-0.5 = imizuzu engu-1.5 = imizuzwana engu-90

Okufunwayo: Isivinini esimaphakathi

5 Ukunyakaza kwe-parabolic Umsebenzi kanye namandla e-kinetic Ukunyakaza okuqondile Ukunyakaza okuqondile nokuqondile Izinkinga nezixazululo

1. Ibhola liphonswa lisuka phezulu kwesakhiwo ngesivinini sokuqala esingu -8 m/s nge-engeli engu-20 ^o ngaphansi kwe-horizontal. Ibhola lishaya phansi ngemva kwemizuzwana emi-3.

a) Ibanga elingakanani ukusuka phansi kwesakhiwo ibhola elithinta umhlabathi

b) Liphakeme kangakanani ibhola eliphonswe endaweni

c) Ubude bebhola bufinyelela kumamitha ayi-10 ukusuka endaweni yokuphonsa ibhola

1. Ibanga eliphakathi kwemisele emibili yamagagasi ongaphezulu kwamanzi lingama-20 m. Into intanta phezu kwamanzi ukuze ibone ukunyakaza kokudlidliza. Uma isikhathi sokuhamba kokudlidliza okukodwa kuyimizuzwana emi-4, khona-ke ijubane legagasi lingu …. m/s

1. Ama-pendulum amabili alula asezindaweni ezimbili ezihlukene. Ubude be-pendulum yesibili buphindwe izikhathi ezingu-0.4 kunobude be-pendulum yokuqala, kanti ukusheshisa kwamandla adonsela phansi okutholwa yi- pendulum yesibili kuphindwe izikhathi ezingu-0.9 kunokwesheshisa kwamandla adonsela phansi okutholwa yi -pendulum yokuqala. Thola ukuqhathanisa imvamisa ye -pendulum yokuqala ne -pendulum yesibili.

1. Ngemva kokuba ifoloko lokushuna u-A lidlidliziwe, ifoloko lokushuna u-B liyadlidlizwa. Ifoloko lokushuna u-B liyadlidlizwa ngoba…..

A. Ifoloko lokushuna A linobukhulu obufanayo nefoloko lokushuna B

B. Zombili izimfoloko zokulungisa zisebenzisa ibhokisi elifanayo lokuzwakala

C. Ifoloko lokushuna B linokuphindaphinda okufanayo nefoloko lokushuna A

D. Umsindo obangelwa yizimfoloko zombili zokulungisa uyafana

1.

Ukusheshisa okubangelwa amandla adonsela phansi kungu-10 N/kg. Indawo engaphezulu yenhlanzi ecindezelwe ngamanzi angaphezu kwayo ingu-6 cm ^2. Thola amandla amanzi ngaphezu kwenhlanzi asebenza ezinhlanzini.
