Find the time for 10 swings, repeat this 3 times to get an average for 10 swings. Find the time for 1 swing record the results and calculate time in second. My prediction - as the piece of string gets longer the longer it will take to do a swing. Apparatus - We used a stand G-clamp, string, pendulum, stopwatch and a holder. ...read more.

Conclusion

The answer came to 4.12. My prediction - was that as the length of the string went up the time went up. This was correct and can be proved by looking at the graph. Changing - If I had to change anything to this experiment I would make it easier to measure the length of the string as it is extremely hard to get the exact length. Conclusion - From this experiment I have learnt that the length of the string attached to the pendulum effects the gravity force acting on the pendulum swing. By Ollie Prior ...read more.

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

    This can be shown by the formula for arc length = r? with r representing the length (radius) and ? representing the displacement in radians. If r increases so will the arc length (i.e. distance travelled by bob). This assumption may explain the anomalous nature of the results for the lengths of 1.10m and 1.20m.

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

    Thickness variations are a product of the source and history of the material. Oceanic crust is thinner than continental crust. Continental crust is thickest under mountain ranges. Density variations occur due to the presence of concentrated and large mineral deposits or petroleum gas and related liquids trapped in sedimentary rocks and structures.

    This helped me verify and check certain details and also finalise my method. I was able to identify the errors and minimise them as much as possible in order to carry out an effective and conclusive experiment. I am going to use a simple pendulum and count the time taken

  1. Acceleration due to gravity lab

    I noticed that the acceleration of the ball increased as it was dropped (refer to Figure 1). I also noticed that in some trials the ball did not travel in a straight line, it might have moved at an angle.

  2. In this experiment I aim to find out how the force and mass affect ...

    When this is put into the equation of a straight line the lines are replaced as follows, a = y, sin ??= x, g = m, (-F / m) = c. When the results are put into a graph , I can find g by finding the gradient of the line on the graph as shown in Diagram 3.

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

    Several methods can be used to measure the value of standard gravity. Pendulum This method involves allowing a pendulum to oscillate freely, recording the time taken for each oscillation. The length of the string used to make the pendulum, and the angle of the drop will also have to be measured, in order to calculate the value of g.

  2. An Experiment Using a Pendulum to Find the Acceleration due to Gravity.

    If the pendulum is swinging in a circle then the measurements will be less accurate. It could also collide with something, which would disrupt the experiment. They can both be measured accurately, although it is much easier to change the length of the meccano idea.
