1. Time always goes on the X axis and can be measured in seconds, minutes, hours.
2. Distance goes on the Y axis and can be measured in centimeters, meters, kilometers.

Consider the following data of a dog traveling on a straight track. Graph the data. Be sure to label the X and Y axis. Try to make the graph take up most of the space.

Position (m) Time (s)


0 0
10 4
20 8
30 12
40 16
50 20
60 24

2. Calculate the slope of the line you just made. What is the velocity of the dog based on the slope?



3. Now calculate the dog's velocity using the equation:

duckPart II: Calculate the Velocity of a Wind-Up Duck (or similar toy)


1. Place your duck on a flat surface (table or floor) and open an app timer on your phone.
2. Start the duck and the timer. Every 2 seconds, mark the location of the duck with chalk or a marker.
3. Use a meter stick to measure the distance (in centimeters) of each mark from the starting point.
4. Do three trials and record your measurements on the chart below.

Time (s) Distance (Trial 1) Distance (Trial 2) Distance (Trial 3)

5. Graph your data using the trial you think is the most accurate. Don't forget to label the X and Y axis.

6. Calculate the velocity of your duck.
