Random error is an error that arises in an experiment due to unknown and unpredictable changes which may occur in the measuring instruments or the environmental conditions and can be commented on based on the scatters on the graph. One of the possible random error which may occur in this experiment is the rate of oscillations. In the set of results for the 60g slotted weight, there are slight differences between all the 5 readings. This is because although only one person oscillated the rubber stopper, the rate of oscillation each time it oscillates will still be still slightly faster or slower. This is because humans do not have the ability to maintain the speed used to oscillate the rubber stopper. For instance, the second reading only took 9.28s to complete the 20 oscillations which is because the speed used to oscillate the rubber stopper is faster. When the speed used to oscillate the rubber stopper is faster, the time taken for the rubber stopper to complete the 20 oscillations will be shorter and hence, the…show more content…
Therefore, this will affect the precision of the data as when the speed of the rubber stopper is not constant, the time taken to complete the 20 oscillations will differ from one another. When the speed of oscillations is faster, the rubber stopper will complete the 20 oscillations at a faster rate and hence the time taken to complete the 20 oscillations will be shorter. On the contrary, when the speed of the oscillations is slower, the rubber stopper will complete the 20 oscillations at a slower rate and therefore the time taken to complete the 20 oscillations will be longer. A motion sensor should be used to oscillate the rubber stopper instead of oscillating it manually so that the speed of the oscillations can be kept constant to increase the precision of the
