Litaelo tse bonolo tsa Teko ea ho Oscillation ea Pendulum
Sehlooho sa teko: Ho sisinyeha ha pendulum ho bonolo
Sepheo sa teko: Ho fumana phello ea bolelele ba thapo (l), boima ba mojaro (m) le ho kheloha (A) nakong ea ho sisinyeha (T).
Lisebelisoa le thepa: Tripod, Boima bo 'maloa ba ligrama tse 50, Stopwatch, Rula.
Mehato ea ho lokisa:
1. Kopanya tripod jwalo ka ha ho bontshitswe setshwantshong.
2. Tlama mojaro oa ligrama tse 50 ka thapo ea 10 cm, 15 cm le 20 cm (boima ba mojaro bo ntse bo tšoana)
3. Tlama thapo ea 15 cm ka 'ngoe ka moroalo oa ligrama tse 50, ligrama tse 100 le ligrama tse 150 (bolelele ba thapo bo lula bo tšoana)
4. Lokisa oache ea ho emisa
Mohato oa teko oa 1: Tšusumetso ea bolelele ba khoele nakong ea ho sisinyeha
1. Lokisa mojaro oa ligrama tse 50 o tlamiloeng ka thapo ea 10 cm, 15 cm le 20 cm.
2. Tlama thapo ea 10 cm karolong e ka holimo ea tripod joalokaha ho bontšitsoe setšoantšong.
3. Suthisetsa mojaro ka thoko ho 5 cm
4. Lokolla mojaro. Ka nako e le 'ngoe, qala oache ea ho emisa. Emisa oache ea ho emisa kamora hore mojaro o fetohe ka makhetlo a 10. Rekota nako ea ho emisa Tafoleng ea 1.
5. Pheta teko ena o sebedisa mojaro wa digrama tse 50 le bolelele ba thapo ya 15 cm. Ngola nako e pakeng tsa nako tafoleng ya 1.
6. Pheta teko ena o sebedisa mojaro wa digrama tse 50 le bolelele ba thapo ya 20 cm. Ngola nako e pakeng tsa nako tafoleng ya 1.
