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– 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
LINE GRAPHS
• 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
• 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
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.
1. What does the slope of each line on the graph tell you?
The speed each runner is moving
• Which runner completed the 100m race in the least amount of time? What was his time?
• Albert, 12 seconds
• Which runner started out the fastest?• Charlie
• What was Charlie doing between 8 seconds and 10.5 seconds?
• He was stopped
• What does a straight line on this graph tell you? A curved line?
• A steady speed, increasing speed
• At what distance and time did Albert overtake Bob?
• Never!
• What is happening between 9AM and 11AM?• The bikers go 30 miles
• What do you think bicyclist is doing between 11AM and 1PM?
• Taking a break (not moving)
• What was the total distance covered by 11AM, 1PM, and 4PM?
• 30 miles, 30 miles, 60 miles
• What was the average speed of the bicyclist between 9Am and 11AM?
• 15 mph S= D/t 30miles/2hours
Exit
• A plane traveled North 1500 miles in 5 hours. What is the plane’s velocity?
