Preliminary Questions
(Pre-Labs must be submitted to the Physics lab on separate paper (not in your notebook) before your lab period. See Lab Points)

1. Sketch how a graph will appear for applied force and length of a spring with force plotted along the x-axis.
        - On the graph, indicate zero force and zero spring length. (Note, a spring will have some length with zero force)

2. For a graph of applied force along x-axis and length along y-axis, slope =  length / force.  Write down an equation of how this graph slope relates to spring constant k. Do this by writing an equation in terms of slope starting with  k = 

3. Draw a sketch of the experiment "Determining ceiling height with a laser" (from your first lab period). On the sketch show what you measured. Then show your calculation for determining the ceiling height from these measurements.
