Work = Force x distance
Work = (Force)(Distance)
W = Fd
Problem

heavy object up to a greater height?

ANALYSIS
1)
How did the
weight (force pulling down) affect
the amount of work done on the
object?
2)
How did the
distance affect the amount of work
done on the object?
3)
Compare/Contrast
the trial with the least amount of work
to that with the most amount of work.
4)
What is your
Independent Variable?
5)
What is your
Dependent Variable?
6)
What are your
Constants?
Friction Lab Analysis Questions
1) What is your Independent Variable?
2) What is your Dependent Variable?
3) What are your Constants?
4) Which surface had more friction? Use your Data from the table to prove this.
