Mutu wa kuyesera: Lamulo Lachiwiri la Newton
Cholinga cha kuyeseraku: - Kufufuza ubale womwe ulipo pakati pa mphamvu ndi kufulumizitsa
- Kufufuza ubale pakati pa kulemera ndi kuthamanga kwa magazi
Zipangizo ndi zipangizo: Njanji, magetsi, kuwala kwa malevel ambiri, sitima yoyendetsera zinthu, chojambulira nthawi, tepi, zolemera za magalamu 50 (3), zingwe zolumikizira.
Njira zokonzekera:
1. Konzani njanji, ikani chojambulira nthawi monga momwe chithunzichi chikusonyezera.
2. Ikani ngolo yoyendetsera zinthu kumanja kwa chojambulira nthawi. Ikani cholemera pamwamba pa ngolo yoyendetsera zinthu.
3. Lumikizani tepiyo ku chojambulira nthawi ndikulumikiza kumapeto kwa tepiyo ku ngolo yoyendetsera ntchito.
4. Ikani magetsi amagetsi pa 12 volts
5. Lumikizani magetsi ku gwero lamagetsi ndikuyatsa chojambulira nthawi.
6. Ikani chojambulira nthawi kuti chigwire ntchito bwino
Gawo loyesera 1: Ubale pakati pa mphamvu ndi kufulumizitsa
1. Ikani chitsulo pamwamba pa tebulo.
2. Lumikizani katundu wa magalamu 50 ku dynamic train pogwiritsa ntchito ulusi.
3. Yatsani chojambulira nthawi
4. Tulutsani katunduyo kuti katunduyo agwe momasuka ndikukoka sitima yoyenda.
5. Zimitsani chojambulira nthawi pamene galimoto yoyenda ikufika pansi pa ndege yopendekera kapena pamene katundu wafika pansi.
6. Chotsani tepiyo pa dera
7. Bwerezani kuyeseraku pogwiritsa ntchito magalamu 100 ndi magalamu 150.
Kusanthula Deta ndi Deta 1:
Nthawi yopuma (t) = nthawi (T) = 1/f = 1/50Hz = masekondi 0,02
50 Hertz ndi ma PLN frequency.
Kulemera kwa katundu = 50 magalamu = 0,05 kg
Kulemera kwa katundu (mphamvu yokoka) = (0,05 kg)(9,8 m/s) = 0,49 N

Kukambirana:
1. Kodi pali ubale wotani pakati pa mphamvu ndi kuthamanga, mphamvu ikakhala yaikulu, kuthamanga kumakulirakulira?
2. Kodi pali ubale wotani pakati pa kulemera ndi kuthamanga, kulemera kwakukulu, kuthamanga kwambiri?
