Your work on the ball down the ramp has been received. We will look at your data later in the context of the entire group's data on this experiment.
The surface might indicate a slight slope but the findings hold true.

no, they actually confirm this. The steeper the slope, the faster it gained velocity.
I believe it is do to the fact that at higher slopes, more positive energy is available to be converted.
The greater the slope, the higher the average velocity.
The built up positive energy being converted to kenetic energy.
