From an experiment (using different elastic one stiff and other less stiff ) • When you use different elastic materials, what changes occur in the shapes of the graphs? Is there a correlation between the type of material and the shape? (Answer generally what occurs ) • When you used a stiffer or tighter clastic material, what effect did this have on the duration of the impulse? What affect did this have on the maximum size of the force? Can you develop a general rule from these observations?
