Do you do more work going straight up a mountain or taking the longer scenic route around to the top?

AB

Work = Force (N) x D (m)

or W= Fd

Conclusion/Summary:

1.Is your hypothesis right or wrong? Explain.

-Restate your hypothesis

-State whether right or wrong

-Use data (#’s) to support why hypothesis is right or wrong

- your group data, B block class data, and 8th grade combined class data

2.Explain your results(the answer). What is the relationship between work of A (straight up) work of B (scenic route)?

- use the formula W = F x d (use force #’s from your group data)

Distance D/m

Work (W=F x d) in joules
