Litaelo tsa Teko ea ho Oscillation ea Selemo
Sehlooho sa teko : Ho sisinyeha ha selemo
Sepheo sa teko : Ho fumana phello ea boima (m) le ho falla (A) nakong ea (T) ea ho sisinyeha.
Lisebelisoa le thepa : Tripod, Boima bo 'maloa ba ligrama tse 50, Selemo, Stopwatch
Mehato ea ho itokisa :
1. Kopanya tripod jwalo ka ha ho bontshitswe setshwantshong.
2. Leketlisa seliba hodima tripod
3. Lokisa oache ea ho emisa
Mohato oa teko oa 1: Tšusumetso ea boima (m) nakong ea (T) ea ho sisinyeha
1. Leketlisa boima ba digrama tse 50 hodima sediba.
2. Hula boima tlase ka 2 cm
3. Lokolla selemo. Ka nako e ts'oanang, qala stopwatch. Emisa stopwatch ka mor'a hore selemo se fetohe ka makhetlo a 5. Ngola nako e pakeng tsa nako ho Tafole ea 1.
4. Pheta teko u sebelisa mojaro oa ligrama tse 100. Ngola nako e pakeng tsa nako ho Tafole ea 1.
5. Pheta teko u sebelisa mojaro oa ligrama tse 150. Ngola nako e pakeng tsa nako ho Tafole ea 1.
