Forces in action!

Today we were investigating how different surfaces can affect the distance rolled by a toy car. We had to make our experiment a fair test by keeping certain factors the same, such as how steep the slope was and the car we were using.

We made predictions and then tested them.

We thought of different reasons why the car travelled more slowly on some surfaces.  We concluded that the more friction there is, the slower the car travels.
