How do different surfaces affect a moving object?
We decided to use a pushing force on a wheeled object to see how far it would go on different surfaces.
We predicted what would happen using our knowledge.
We had to make it a fair test so some things had to stay the same each time. All the surfaces had to be level and the same force used.
We tested how far our vehicle would travel on each surface with the same force each time. The variable that changed was the type of surface: some rough and some smooth. We will be discussing our results tomorrow.
