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

  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

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.


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 pendulum will be drawn back to an angle of 30� (measured with a protractor) and then released. -The stop clock will be started, 10 oscillations counted and at the end of the 10th oscillation, the clock stopped. -For each different length of the pendulum, the experiment will be repeated 3 times, in order to obtain an average.

    I shall account for any anomalous results from preliminary experiments to make sure the same problems are not repeated. If these anomalous results do re-occur I will suggest ways of overcoming them and what might be the probable cause of them.

    P.E = K.E mgh = 1/2mv2 The formula can be simplified 20h = v2 SQRT(20h) = v This formula will give us the average velocity for the trolley going down a ramp of h metres high. Once we have found this we can actually use the equation for average speed

    Now you are ready to conduct the experiment and obtain the results. Hold the bob and move it 10? to the right. The amplitude of 10? is measured by looking at the protractor behind the string. Release the pendulum, so it starts swinging.

    Note: The friction on the string caused by the air will affect the results. Ideally, this experiment would be conducted in a vacuum. However, we have no equipment in school that we could use to achieve this. So, therefore we will have to conduct the experiment with the knowing that

    * Pulley: A smooth running surface for the wire, over the edge of the table. Hence this will let the string extend with force with minimal friction. * Masses: These will be used to put load on the string to give an extension reading.

    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.
