Title of Lab Practice: Physics and Measurement

Problem Question: How does volume affect the falling speed ofan object?
Hypothesis: If the wooden block is bigger, then it will fall faster to the ground

Organizing Data Using your data from the first data table, calculate the volume of the wooden block for each trial. The equation for the volume of a rectangular block is volume= length x widthx thickness.
Analyzing Data Use your data from the first table and your results from item 1 above to answer the following questions.

a) For each block, what is the difference between thesmallest length measurement and the largest length measurement?

b) For each block, what is the difference between the smallest calculated volume and the largest calculated volume?

c) Based on youranswers to (a) and (b), how does multiplying several length measurement together to find the volume affect the precision of the result?

Analyzing Data Did the block always fall from the same heightin the same amount of time? Explain how you found the answer to this question.
Constructing Graphs Using the data from all trials, make a scatter plot of the distance versus the time of the block'sfall. Use a graphing calculator, computer, or graph paper.
