Pendulums and fractals!!! :D

  I have been learning about pendulums in science class lately and I think they're super cool so I decided to post about them.

So at school we did an experiment to see whether there was a relationship between the length of the string and the period of a swinging pendulum. To find out we timed the period with different lengths of string to see if we could find a pattern. we found that there is in fact a relationship because it takes longer for the string to reach the farthest point when it is longer and a shorter time when the string is shorter. We graphed our data and found that the line appears to be straight but then near the end it dips. we did more tests and found that no matter what lengths you use for the graph it dips at the end. It turns out that it was a fractal.  a fractal is a complex geometric pattern exhibiting self-similarity in that small details of its structure viewed at any scale repeat elements of the overall pattern.
