Friction Part 1 – slides
To learn about friction, we tested different materials on a slide and how fast they would go down the slide. We talked about how friction works against gravity. We compared different items against each other, we compared the same items with added weight to one of them, we compared the same items close to each other and far apart. We also talked about other things that might change how fast items would go down the slide such as the steepness of the slide and possibly the length.
