The Factors which Affect the Time for One ull Oscillation of a Pendulum
Most of the procedure was suitable because it gave a useful and relevant outcome but it could have been improved in a number of ways. The reliability of the evidence could be increased by making the angle more precise, making sure the string is taut when the pendulum is released and making the string the exact length it should to be. The anomalous results I have may be down to a number of reasons but could mainly be blamed on my releasing the pendulum and providing it with an external force, which would affect the period. My timing of the stopping and starting of the stopwatch could be inaccurate. The overall results may be a 1/100 of a second out because I used the gravitational field strength of 10 when the actual field strength may be different. If the above improvements were added in, the results would be more accurate and reliable. To further this work, I would repeat each length providing more accurate averages. I would provide additional evidence for my conclusion by increasing the range of lengths and decreasing the intervals between the lengths to five centimetres. These additions would extend my investigation further.…
