relationship: mass and inertia
inference: The inertia depends on its mass
hypothesis: When the mass increases, its inertia also increases
Aim: To study the realtionship between mass and period of oscillation
Variables : Manipulated - Mass, m
Responding - Period of oscillation, T
Fixed - The distance of the centre of plasticine bob to the point where the hacksaw blade is clamped
Apparatus and Materials : Hacksaw blade, G clamp, Table, metre rule, stop watch, plasticine, triple beam balance
Arrangement of Apparatus : *please refer to the picture upload*
Procedures :
1. The experiment is set up as shown in the diagram above.
2. A 20g mass of plasticine bob is weighed.
3. The plasticine bob is then attached to the free end of the hacksaw blade.
4. The plasticine bob is displaced.
5. The time for 10 oscillations, t is taken.
6. The period od oscillation, T is the calculated.
7. The results is recorded in the table below.
8. The experiment is repeated using plasticine mass, m of 30g, 40g, 50g, 60g.
9. Care is taken so that the distance between the centre of the plasticine bob and the point where tha hacksaw blade is clamped is always the same throughout the experiment.
Tabulation : *refer to the picture taken/upload*
Analysis.
1. A graph of T(squared) against m is drawn.
2. From the graph,
a) determine the value of period of oscillation, T when mass, m = ____ g
b) determine the value of mass, m when period of oscillation, T is ____ s .
3. Calculate the gradient of the graph.
Conclusion :
Precautions : -avoid parallex error
-repeat experiment
untuk tabulation : t/s (tukarkan kpd) > 10 oscillation
T/s (tukarkan kpd) > 1 period of oscillation
value of t/s (ke bwh) > 4.00 5.08 5.26 5.82 6.04
value of T/s (ke bwh) > 0.40 0.58 0.52 0.58 0.60
p/s terpaksa letak dlm blog sbb handout utk lab report ada satu je n kalau nk photostate takut tak sempat sbb due hantar hari selasa
p/p/s ni semua utk izzatul y xdek fb huhu.. kalau x boleh je dia tgk dkt GC.
p/p/p/s hey izzatul! u should thank me!
assalamualaikum
