7 Random Facts 09/30/11
7 Random Facts 09/30/11

Controlled variables are measured by,
How far we pulled the blocks
How fast we pulled the blocks
The surface type
Manipulated variables are measured by
Surface type

Surface area I learned that different surface types make more/less friction, they don't all have the same friction measurement.
I learned that the more weight on a surface type will make more friction because it is heavier.
I learned that if you put more surface area on a surface type the friction stays almost same!

When you pull a block across why does it measure friction?
It measures friction because when you pull a block across a surface area the friction goes the opposite way!
