Over-arching Inquiry:
How can an understanding of Mechanical Advantage and Mechanical Efficiency help to create a useful application for everyday life?
(teacher note: you can always have students create the question by phrasing this as a statement for them. e.g. Mechanical advantage and Mechanical efficiency are important for everyday life.)
Learning Goal: Understand the nature of and the relationship between input and output forces in machines and how these apply to mechanical advantage and mechanical efficiency.
