The graph representing average speed ( s ) vs length ( m ) and square of average speed ( s² ) vs length ( m ) is shown in the image attached below.
The value of time period of three trials each for all three length are given. The average value of all the given time periods are found by using
s = ( s1 + s2 + s3 ) / 3
Then the average time period is squared. In graph 1, the the length of pendulum ( y-axis ) is plotted against average time period ( x-axis ). In graph 2, the the length of pendulum ( y-axis ) is plotted against square of average time period ( x-axis ).
Therefore, the graph representing average speed ( s ) vs length ( m ) and square of average speed ( s² ) vs length ( m ) is shown in the image attached.
