2018 #2 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #2 from the 2018 AP Physics exam, focusing on determining the resistivity of conductive dough cylinders. It explains how to graph resistance and length to find resistivity, emphasizing the importance of labeling axes and using a straight edge for accuracy. The tutorial also discusses how the shape of the dough does not affect resistivity and outlines an experimental procedure to test if resistivity changes with temperature.

Describe an experimental procedure to determine if the resistivity of the dough depends on temperature.

What factors must be kept constant when measuring the resistivity of the conductive dough?

What is the expected relationship between the current and the temperature of the conductive dough?

Why is it important to allow the dough enough time to experience a significant temperature change during the experiment?
