Conditions of Use
What have you learned about friction in lesson 6, Inquiries 6.1, 6.2, and 6.3?
6.1: I learned that if you slide a block across a rough surface there is more friction.
6.2:I learned that if there is more weight that your pulling then there is more friction force.
6.3: I learned that if you change the surface area then the friction force varies.
How did you measure sliding friction in the labs you did in class?
We measured the sliding friction in newtons.
What did you learn about controlled variables? Give examples of how you controlled variables during your labs.
I learned that controlled variables are things that you don't change during your test. In our labs we kept the sliding speed the same in all of the labs. Controlled variables are things that you do not mess with.
