Conditions of Use
6.1 I learned that different surface types make more or less friction, like they don't all have the same amount of 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.
How far we pulled the blocks
How fast we pulled the blocks
The surface type
Controlled = we were in control of the things
Manipulated = we changed it
