thanks you for the help! Luckily I think I've found the mistake, which was just due to a false assumption I made, luckily it is an easy fix! Nonetheless, thank you for the clarification on the evaluation for my IA, you helped me form a clearer understanding of what goal I am trying to reach in...
Thanks for pointing out my minor mistakes, unfortunately they are in my conveying of the issue, and not in my processing of data. I meant to say the 'slope of the graph of the maximum height reached (y-axis) against the spring compression squared (x-axis) since this gives me a linear equation.
I did my Physics IA on comparing the maximum height reached by a projectile (shot by a spring) and the compression of that spring.
In my experiment I found the maximum height reached by a metal ball shot directly upwards in comparison to the amount the spring was compressed.
To test the...
