An investigation of the factors affecting the period of a pendulum

I could investigate the following factors:

  • Angle of displacement
  • Length of string
  • Pendulum weight

I am going to investigate and see if varying the length of string will affect the period of the pendulum.

My prediction is: The longer the string the longer the period. The period will be longer as the pendulum has farther to travel. My theory is demonstrated below.


I made my prediction based on a previous experiment I have done. The length affected the period as stated above and I think this will happen again in this experiment. I looked at a clock with a pendulum to see how it worked.

Not to swing the pendulum near others

To ensure the test is accurate I am going to:

  • Run the experiment 3 times and take an average
  • The time for one oscillation is very small so I have decided to measure 10 oscillations then divide the result by 10 so I obtain a more accurate set of results.
  • Double check all measurements of string
  • Use the same angle of displacement (amplitude)

In my experiment I used the above ways to keep the test fair and accurate. I also did the experiment 3 times and so I could take an average.

Where we hung the pendulum. I would change this because sometimes the pendulum hit the table and clamp stand whilst swinging so ideally we would have liked to hang it from the ceiling or hook.

I also think I have enough evidence to support my conclusion as all our results showed the same relationship between length of string and I also referred to the clock mechanism in my prediction so I think I have enough evidence to support my conclusion.

I could also perform more experiments to research the pendulum more. By changing the weight of the pendulum or even changing the angle of displacement. Doing this would give me a wider knowledge of why the pendulums oscillations vary

    It would also keep the temperature constant ensuring that the ball receives exactly the amount of heat required for its bounce test. If enough balls of the same type were available, it would have been better to use a different ball for each temperature that needed experimenting on so that

  1. An Investigation of the Factors affecting the Period of a Pendulum.

    e.g (9 + 8 + 10) / 3 = 9 The simple pendulum consists of a small bob of mass suspended by a light inextensible thread of length (l) from a fix point. Pendulum is a device that converts its energy back-and-forth between Potential and Kinetic energy.

  2. Investigate the factors affecting the time period of a pendulum

    This means that it will have more gravitational potential energy to convert into kinetic energy. The formula used to work out gravitational potential energy is. Using the angle from which the pendulum is dropped as a variable would affect the height and therefore the gravitational energy as demonstrated above.

    Opposite = V (Sine Theta) In the below diagram, the weight, 'Mg' (mass into gravity), can be resolved into two components. The first component 'Mg cosine' compensates for the tension in the string. 'Mg sine' is the component that provides the restoring force.

  2. An Investigation to See Which Factors Affect the Swinging Of a Pendulum

    > Procedure: We will attach a string to a stand. At the end of the string, we will attach a weight. We will then release the string and the weight, and we will let it swing through the air. We will time how long it takes for the weight to travel through the air and return to the starting point.

    (Figure 2 from gpc.edu/~pgore/geology/geo101/ crustaldeform.php). This graph shows how the initial linear section of the graph is when strain is proportional stress. The area marked "X" on the graph is the elastic limit or yield point, this is the point of no return from this point the material is permanently deformed and can no longer return to its original state.

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

    This will help me to identify a clear pattern in my results. - If any anomalous results are identified, readings will be repeated. This will ensure that all readings are sufficiently accurate. - To ensure that the velocity is not affected, I will ensure that there are no obstructions to the swing of the pendulum.
