Oops my bad! As I said I'm tired :p I meant to say v^2 And I've done it by hand but its still a straight line. I have a feeling its because the curve is rather shallow so it is hard to see it on my graph.

Ok now my problem is this- Ignoring resistances (I'm factoring these in later), if a ball rolls down a ramp the initial GPE energy goes to KE. So the equation would be mgh=(1/2)mv*2 so mass cancels out leaving gh=(1/2)v*2 multiply by two gives 2gh=v*2. So I have plotted a graph of change...
