Lesson 4: Distance Time Graphs
A DistanceTime graph is a graph that displays the position
of an object over time.
Time is always the independent variable.
Distance is the dependent variable.

At what speed is car A
traveling?
How many times faster than
car B is car C traveling?
At what speed is car D
traveling?
Interpreting a distancetime graph

A basketball ball was bounced from various heights and the respective bounce heights were recorded. The scatter plot is below. Sketch the scatter plot.
a) Describe the data.
(Direction, strength, shape) b) The experiment was repeated with a squash. Add its data to your sketch. (Dotted)
Oct 249:48 AM
A bag was hanging on an elastic and books were added to it. Its height was recorded and a scatter plot was made. Sketch the scatter plot.
a) Describe the data.
(Direction, strength, shape) b) The experiment was repeated using much larger books. Add this data to your sketch. (Dotted)
Oct 249:53 AM
A long piece of candy was eaten by taking uniform bites. Its length was recorded after each bite. The scatter plot is shown below. Copy a sketch of the graph.
a) Describe the data.
b) The same candy is available in a shorter Halfsize. This experiment was repeated exactly, using the half size "Candy by the Foot". Add this data to your sketch. (Dotted)

A cylinder was filled with water and then allowed to drain from a hole in the bottom. The height and time were recorded at various points. The sketch is provided below. Copy the scatter plot.
a) Describe the data.
b) The experiment was repeated and a larger hole was used. Add this data to your sketch. (Dotted)
Oct 249:59 AM
Ten bean bags were tossed into a bucket from various distance away. The results were recorded and the scatter plot is shown below. Make a sketch of the graph.
a) Describe the data.
b) Why was it important NOT to change the shooter(s) at different distances? Discuss.
c) If this experiment was repeated and the experimenter was given a day to practice, how would the results be different? Add this data to your sketch. (Dotted)
d) Could this line of best fit be used to reasonably extrapolate to 10 m? Discuss.
