Question 2:
Table 1 shows the experiment results to study the relationship between mass and inertia.
(a) Diagram 2 shows the reading of stopwatch for 5 complete oscillations of 50 g plasticine.
State the reading of the stopwatch in Diagram 2 [1 mark]
(b) Predict the time taken for 5 complete oscillations if the mass of plasticine is 25 g . [1 mark]
(c) Based on Table 1, draw a line graph of time taken for 5 complete oscillations against the mass of plasticine. [2 marks]
(d) The following is a statement related to the experiment.
Based on the experiment, how can you prove the statement? [1 mark]
Answer:
(a) 41 seconds
(b) 29 seconds
(c) Draw a line graph of time taken for 5 complete oscillations against the mass of plasticine.
1. All points are correctly moved
2. All points are connected and form a linear graph
(d) If the mass of plasticine used is 20 g , it is found that the time taken by the plasticine for 5 complete oscillations is 26 seconds compared to if the mass of plasticine used is 60 g , the time taken by the plasticine for 5 complete oscillations is 46 s .
