 Friction. 6.2 I learned that the more weight on a surface type will make more friction. 6.3 I learned that if you add more surface area on a surface type the friction stays pretty much the same. The reason we were measuring friction is because we pulled a block across a surface for a certain amount of length which made the force pull backwards which is friction. Controlled variables: How far we pulled the blocks How fast we pulled the blocks The surface type Manipulated variable: Surface type Weight Surface area Controlled = we were in control of the things Manipulated = we changed it Article posted May 14, 2012 at 02:16 PM • comment • Reads 884 • Return to Blog List Add a CommentPosted Comments |
