Simple Pendulum Experiment. Aim: To determine the acceleration due to gravity,g, using a simple pendulum.

Extracts from this document...


Date: Feburary 8,2012 Title: Simple Pendulum Aim: To determine the acceleration due to gravity,g, using a simple pendulum. Apparatus: wooden blocks, thread, stand, meter rule, stopwatch, bob, boss & clamp. Procedure& Precautions: A string measured to be over 1 meter, so as when it's length was being adjusted there was enough string to pull on from between the wooden blocks, was tied to a bob. The end of the string was then placed between two wooden blocks and adjusted so that the length of the pendulum was 1 meter. ...read more.


The angle at which the pendulum is drawn out to should be small. The smaller the angle, the closer the harmonic motion it will behave because the restoring force is acting tangent to the arc - the pendulum moves through instead of being outside of it. The time taken for 20 oscillations with the length of the pendulum being 1 meter was recorded but was also repeated for accuracy. ...read more.

    The Simple Pendulum Experiment

    4 star(s)

    However, most of these can be resolved. First of all, I must address the safety of the experiment. As the mass is swinging from the pendulum, the clamp stand has the tendency to tip because of the laws of moments.

  2. Determination of the acceleration due to gravity using a simple pendulum.

    * Time period of the pendulum. * Size of the bob: The same bob will be used throughout the experiment, so this will remain constant. * Displacement of the pendulum: This will remain constant at 10 degrees. * Air resistance: It is assumed that there is no air resistance and

  1. Determining the acceleration due to gravity by using simple pendulum.

    This is called a small angle approximation. If we keep to small angles we find the period of the pendulum to be: T = 2p (L/G).5 Where L is the length of the string or wire to the centre of mass of the bob and g is the acceleration due to gravity.

  2. Investigating the period of a simple pendulum and measuring acceleration due to gravity.

    too many risks and it can be carried out in classroom conditions. But in order not to hurt others and myself while carrying out this experiment a few safety steps will be followed. * The Clamp stand will be placed away from the edge of the table.

  1. Period of Oscillation of a Simple Pendulum

    By timing how long it takes for a complete oscillation to take place (an oscillation is from the starting point back to the starting point again. I will count the time for ten oscillations and then divide the resulting figure by ten to get an average time.

  2. Measuring Acceleration due to Gravity using a simple Pendulum.

    In the preliminary experiment a range from 0.2m to 2.4m was used. This gave a better understanding of what measurements to use in the final experiment. Length (m) Time for 20 Oscillations (s) Period (s) 2.400 63.21 3.16 2.200 62.39 3.12 2.000 59.78 2.99 1.800 57.10 2.86 1.600 56.72 2.84

    and then using this equation, I will be able to determine g. Variables The independent variable will be the length of the pendulum and the dependent variable will be the period of oscillation that is how long it takes for the pendulum to complete one oscillation.

  2. Determination of the Acceleration due to Gravity on the Earth’s Surface

    As the tape accelerates through, the dots made on the tape space further and further apart, with the increasing speed. A dot is made every 0.02 seconds with the timer, and as the dots space out, the distance travelled by the tape increases with each 0.02 seconds.
