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?
