In this unit, students will continue their study of forces by relating fluid resistance, such as drag through the air, to fluid particles and their movement. They will also apply their understanding of forces to define and quantify their own model describing the turning effect we observe. Students will learn how to calculate a moment, and how the Principle of Moments describes rotational equilibrium.
The unit will provide opportunities to collect and record data in tables, plot data on a graph, and use graphs to make conclusions.
