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 mass of the pendulum (bob) will remain the at 500g throughout, ensuring there is no changes in the forces acting upon the pendulum. -The clamp stand will be securely fixed by the device of a G-clamp so that it doesn't move, affecting the results.

    Investigating how the Length of a Pendulum affects its Period

    But I do not think this will be a very big change, just large enough for it to be noticed as a trend. I think this as longer swing is closer to the ground and so has less gravitational potential energy than a shorter string, and so it takes longer to complete one full swing.

    Carry out the procedure again, as above, changing the lengths from 1m to 0.9m, 0.8m, 0.7m, 0.6m, 0.5m, 0.4m, 0.3m, 0.2m and 0.1m. 15. Repeat the experiment for all the lengths 3 times, so that you obtain 3 times for how long it took the pendulum to complete 30 oscillations, for each length.

  1. What affects the time period of a pendulum.

    3,2,1, go. We should also let the pendulum swing for ten periods and then divide by 10 to reduce the effect of human error. Note: Although during my research I ascertained that the mass of the bob does not effect the period of the pendulum, I should still keep this constant, as I should only have one variable in my experiment.

    Measurements of wire length in meters and wire diameter in millimetres (later converted to meters by dividing by one thousand). 3. Record the measurements of string length and diameter. Then work out cross-sectional area of the wire by halving diameter to get the radius of each string and then put in to the formula ?

    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.
