Wheels Post-Laboratory Names: __________________________________________________________________ Date: ____________ ! For each of the five wheels in the robotics kit, find the linear distance traveled in one revolution in centimeters. To do this, record measures for each wheel three times and report the average of the distances. If working in a group of three, each student should contribute a distance value.

Choose one row from your table and fill in the following. Wheel 3. Diameter from calculation Now calculate the percent error of your measurement, (write it as a percent, and be sure to take the absolute value) Percent Error = 4. Average estimated Diameter The calculated value of distance- estimated value of distance • 100 The calculated value of distance Why is there an error?
