Introduction

Investigation the simple pendulum

Plan

For my experiment, I am going to investigate the simple pendulum. The simple pendulum is a piece of string attached at one place from where it will pivot; at the bottom of the piece of string is some kind of bob.

There are certain variables that have to be taken into account: Air resistance, time for one swing (period), the weight of the bob, the angle of swing and the length of the string.

I don’t feel that I really need to take into account the air resistance, as the string is thin and the bob is round, it will cut through the air easily and will not slow down the pendulum a great deal.

        I took some preliminary experiments to

I am going to set up the equipment and then I am going to start with 60cm of string as this is my highest value. I will attach the weights to the bottom of the piece of string they will be 50g in total. I will measure 50º away from vertical then let the string go from there. I will measure the time it takes for 10 periods to take place then divide that time by ten to get an average reading. I will do this, as it would be difficult to measure the amount of time it would take to swing for one period, it is more accurate this way. I will repeat each of the readings 3 times and then find the average of these.

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

    Although this experiment produced no anomalies, I will take three readings of each value during my final experiment and take an average. I will also measure the time taken for 5 oscillations rather that 1 and then divide the result by 5.

    By increasing the length of the string, one side of the arc i.e. the radius increases and hence the object has to travel through a larger arc and a greater distance provided that the mass of the object and the angle remain constant.

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

    I can now say that the length of the pendulum does have an affect on the period, and as the length of the pendulum increases, the length of the period will also increase. I will draw a graph of P against L.
