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.

    By using these averaging techniques it minimizes random errors. The period of pendulum depends upon length (L) and the value of acceleration due to gravity (g), s described in the following equation Rearranging this equation gives an expression that can determine g, 4) Substitute your values for L and T into this equation to get g, which is the acceleration due to gravity.

    Thus when a coin and a feather are dropped from the same height in a vacuum, they both hit the ground at the same time. This is an important principle in science. If air resistance is the same for two objects that are dropped, they will gain speed at the

    / Vg. This however, would not produce a linear graph and so calculating the gradient would be more difficult and ambiguous than if using a linear graph. So for the theory of the simple pendulum: To obtain a linear graph, take the squared equations which enables g to be deducted when plotting T� against L.

  2. Determining the Acceleration Due to Gravity

    pendulum will continue past the equilibrium, and so the pendulum will continue to oscillate like this. All energy in a pendulum system is conserved, either in the form of potential energy or kinetic energy. At its highest point (furthest away from equilibrium)

    Make sure when dropping the ball the person dropping it does not exert extra force on it, as that could tamper with your results. Repeat these steps at least two more times for this height, you can call it Height #1.

  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.
