Experiment outline:
This experiment is to find out if the length of the pendulum string will affect the period of a simple pendulum. The experiment was conducted with strings from length 10cm to 60 cm , & six different timings were recorded for each string of different length. The results of the time taken for one oscillation of pendulums of different string length were used to find the relationship between the pendulum string length and it's period.

Conclusion: when the pendulum string length increases, so does the period.

Procedure :
1. Create pendulums of different string length, from 10 cm to 60 cm.
2. Record the time taken for 20 oscillations for each pendulum of different string length six times.(T)
3. Record findings in a table
4. Use the information recorded to find the time taken for one oscillation of pendulums of different string length
5. Plot a graph of  T (s)/  L (cm).  Where L is length of string and T is time.



Table for findings :

Graph for findings : 

Interpretation of graph: 

As the length of the pendulum string increases, so does the time for one oscillation increase. 

Equation: T= M( L) + C.    Where M is the gradient of the graph.
