AIM:To determine the relationship between a period and the length of the simple pendulum.


  • Long thread
  • Bob
  • Metre rule
  • Stopwatch
  • Retort stand
  • Clamp


  1.  The clamp was attached to the retort stand.
  2.  A metre rule was used to measure the different length of the thread.
  3.  The thread was attached to the clamp with the bob attached at the bottom of the thread.
  4.  The length of the thread was noted.

 Should be very careful when counting the oscillations. The thread should be properly measured. The way should be clear once the oscillations have started or else it can cause errors to take place. We should check if there is zero error. The bob should oscillate in a right position.


We can conclude that if the thread has got a long length, the time it will take to complete 20 oscillations will be more.

    The Simple Pendulum Experiment

    4 star(s)

    The Top-pan balance will measure the mass of the plasticine to be added. Once I have recorded my results, I will use the formula (as stated above) to work out the time of one oscillation of the pendulum. I will then plot a graph of mass against time to help

  2. Period of Oscillation of a Simple Pendulum

    Gravitational acceleration is the only factor that decides how fast an object may fall in a vacuum. Pendulums with large masses should therefore be no slower or quicker than pendulums with small masses. The data that I collected was not brilliant because the results digressed to such large extents in

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

    This again should influence the accuracy of my results. Table of averages: Length of string (cm) Period (secs) 50 1.45 40 1.28 30 1.13 20 0.91 10 0.61 Using the formula, T = 2 L g found in the Scientific Theory, I calculated the perfect results that should have been


    By the second definition, the number 3.1415 is more precise than the number 3.14. Look at the examples below: * Examples from my results contain the results for 10cm length in which as we can see the average of my results is close to that calculated from expression but the three results are far from each other(precise but not accurate)

  1. Factors affecting the time period of a simple pendelum

    Frequency is the number of oscillations per second, which is measured in hertz (Hz). Angular Velocity- the angle at which the radius vector subtends at the center in one second is called the angular velocity of the particle. Its unit is radians per second. That is, (rad s-1) ?

  2. Investigation of the factors affecting the time period of a simple pendulum

    - Human reaction time. Depending on human reaction time, the measurement period time could have been measured inaccurately, due to slow reactions when setting the stop-clock etc. This could have been improved by involving another person to aid me with my experiment for a quicker reaction time.

  1. In this Coursework, we were given the task of investigating some factors which affect ...

    It will equal: 20 / 360 * ? * 2 = 0.35m Situation no.2 : When the length of string i.e. radius is 2 m and the angle is 10 degrees, we could use the formula X/360 * ?D, to work out the circumference of the arc. It will equal: 20 / 360 * ?

  2. Investigating the Period of oscillation of a Simple Pendulum

    Once the bob is released, this gravitational force is able to act on it, thus moving it downwards towards its original hanging point. We can say therefore, that as it is released, the GPE is converted into Kinetic Energy (KE)
