Between which two points is there a constant speed?
Points B and C Between
points A and B is acceleration
Between C and is deceleration
Practice GUIDELINES FOR MAKING GRAPHS
• A graph is a kind of picture use to show quantitative data, measurements and numbers collected during an experiment.
• Most graphs have the same basic parts: – title that tells what data is shown in the graph– horizontal axis (x-axis) which usually shows the
independent variable– vertical axis (y-axis) which usually shows the dependent variable
• “DRY MIX” can help you remember how to label each axis. D= dependent or Responding variable goes on the Y axis; Manipulated or Independent variable goes on the X axis.
LINE GRAPHS
• When to use a line graph…– when your data is continuous & specific… you want
to show a trend or change over time – examples: time, height, weight, length, volume,
pressure, distance, temperature, speed, etc…• when using a line graph, the axes must have
equally spaced intervals in a measurement depending on the range of the values in the data
• each point on the line graph has two values, one for the horizontal axis and one for the vertical axis.
• a line graph may have two or more lines plotted on it if there are multiple sets of data measured during the same experiment– if two sets of data are plotted, you must include a
key to show which line represents each set of data

Line Graphs
BAR GRAPHS• When to use a bar graph…
– when you want to show a comparison of your data can be averaged, grouped, or put into categories
– examples: models of cars, brands of hair spray, types of fabric, favorite foods, etc…
• when using a bar graph, the independent variable is displayed along the x-axis (horizontal) and the dependent variable is shown on the y-axis (vertical)
• the bars in a bar graph should be of equal size and should be evenly spaced
• each bar should be different either in color or pattern• you must include a key to show what each bar on the graph represents

Application • INTERPRETING
GRAPHS- • In physics, a graph is
“worth a thousand numbers”. A great deal of information can be obtained by looking and interpreting graphs describing motion (displacement, speed, velocity, and acceleration).
Application • Distance vs. Time Graphs- To
the right is a typical graph displaying Distance vs. Time. One or more objects may be graphed at one time, so you can compare the relative positions, speeds and displacement as they relate to each other.
• Directions: Answer the following questions as they apply to the Motions graphs and diagrams.
1. What does the slope of each line on the graph tell you?
The speed each runner is moving
