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.(adsbygoogle = window.adsbygoogle || []).push({});

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 in height by Velocity and resulted in a straight line graph. I'd have thought this was wrong as by the equation above the change in height is proportional to velocity squared so should it not be a curve?

There's probably something completely stupid I'm doing but I've been doing Physics for 6 days straight so my mind's gone blank.

Any help is much appreciated
