Slope and Distance

After our friction experiments, both classes have been looking at other aspects of forces. In 4G we've been looking the angle of our slope.
We used a protractor to work out what angles were possible on the slope.
We wanted to see how the angle of the slope affects the distance a car goes after it runs down the slope. So, we tried it at lots of different angles, keeping every other variable the same.
We recorded what we found:
In some cases, the bigger the angle was, the further the car went:
Graphed with Desmos
In other cases, as the angle got bigger the distance got longer, but then, after a certain point, it got shorter again:
 Here's a chart that joins together all our results with an average result:
We talked about why there was that strange dip at the end. We had some good answers.

But what do you think?
