They must be able to draw and label the setup, identify variables, state a relationship and setup a graph.They must understand to EXTRAPOLATE and INTERPOLATE from the graph they created. Finally they must use their knowledge of forces and this lab to predict the outcome of a different ball.

For this lab you need:
- Large marble
