How does length affect the time period of the pendulum

Tarun Sridhar 10B


Physics Practical:-

Factor: Length of string holding the bob

Research question: - To find out if the length of the string holding the bob affects the gravitational force against the bob, i.e. the time period.        

Hypothesis: - I think that the increase in the length of the string would result in the increase of the time period (time taken for one oscillation), Because The pendulum holding the longer string should take more time because it has a long way from starting to end point, whereas the pendulum with the short string would have a lesser distance to travel the length of the string is directly proportional to the time period, and the

Method:-

  1. First get all the materials needed
  2. Then connect the string the rubber holder
  3. Connect it  to the pendulum stand
  4. Take out the string, which is put through the rubber and adjust the length.
  5. Record the time taken for 10 oscillations for different lengths

Conclusion

Value of g (acceleration due to gravity) from the above relation we can derive a formula for time period

This equation shows us the relation between time period and length in depth, and the formula can be tested, and using this formula, just substituting in the values would give you the needed value, for e.g. substituting values for G and pie and length we can find the time period.

Evaluation:-

This experiment was successful and I think I could have done better if there was more time so that I could have taken more records for my data which would have made my results more accurate

There were some human errors which were made during the experiment, for E.G. the length of the string measured by the ruler and then stuck between the rubber corks may not be so accurate and also the error made when we use the stop watch

    the same pattern but with a large difference between them, on average, 3.1 seconds due to a systematic error that should have been corrected. There was one anomalous result obtained through the experiment, this was the last reading of the experiment at the length of the pendulum being 0.8m.

    I will repeat the experiment three times for each length; this will give me enough results to create a reliable graph. Whilst carrying out this experiment you have to realise some safety issues that are to do with the equipment we are using.

    It rolls all the way down the ramp, of 2 metres, before it collides with the wall at the bottom. A couple of keen scientists thought it would be interesting to record the time taken for the trolley to reach the bottom and then calculate its average speed.

    Record the time. 13. Adjust the length of the pendulum for the next reading. Remember to measure the length of the string from the middle of the bob to the edge of the wooden blocks where the string comes out.

  1. Investigating factors which affect the period time of a simple pendulum.

    Although this experiment produced no anomalies, I will take three readings of each value during my final experiment and take an average. I will also measure the time taken for 5 oscillations rather that 1 and then divide the result by 5.

    Key factors The key factors affecting my experiment will be extension (a variable), also force will be a variable as I will add weights to change the forces acting on the strings, thus stress and strains will change in each string also.

  1. What affects the time period of a pendulum.

    This acceleration can be calculated by the formula a = -gA. The angle size can also be linked to the arc length, this is shown in the formula, x = LA. With L being the length of the string. This leads us to the equation for acceleration of a simple pendulum bob a = -g/L x.

    This was hard to do but we tried our best in keeping it constant. Independent variables: 1. Length of string: For the string length, we took a wide range of 40-140cm (every 10 cm) and therefore we did trials with 11 different string lengths.
