Unformatted text preview: 8. Use the graph (calibration curve) to determine the magnitude of the unknown mass. Draw a line from the unknown's period on the y-axis to the corresponding mass on the x-axis. Data Mass (kg) Time #1 (sec) Time #2 (sec) Time #3 (sec) Avg Time (sec) T 2 (sec) 2 Unknown Analysis The following questions should be answered as part of the data analysis: What is the relationship between inertial mass and gravitational mass (weight) as scalar and vector quantities? What is the mathematical significance of graphing period SQUARED versus mass in terms of the relationship between these variables? What is the property of inertia in light of Newton's first law of motion? What is the purpose of suspending the cylinder from a ring stand using strings so that the mass does not rest on the inertia balance pan? Is there a difference between the calculations for the cylinder when resting on the pan versus suspended by strings? Explain....
