There are three types of graphs:
• Position vs. Time– Shows the position of an object over time
• Velocity vs. Time• Shows the rate at which the position of an object changes over
time
• Acceleration vs. Time– Shows the rate at which the velocity of an object changes over time
Position vs. Time
QUANTITATIVE (with numbers)
Velocity vs. Time
QUALITATIVE (without numbers)
Different Velocity-Time Graphs (all show changing velocity)

DIFFERENT SITUATION EXAMPLES OF MOTION
Complete with motion maps
Acceleration vs. Time
Constant Velocity (a=0) Constant Acceleration (a≠0)
Now, test yourself
Look at the following position time graphs, and see if you can describe the motion of the object
represented by the graph in complete statements
Answer
• Constant velocity• Moving in the positive direction• Away from the origin
Answer
• Slowing down in the negative direction• Toward the origin• Stopped for an instant• Turns around• Speeding up in the positive direction• Away from the origin
Answer
• Slowing down in the positive direction• Stops for an instant• Speeding up in the negative direction
Answer
• Slowing down in the positive direction• Away from the origin• Then comes to a stop
Answer
• Speeds up in the positive direction• Away from the origin
Answer
• Slowing down in the negative direction• Toward the origin• Then comes to a stop
Answer
• Stopped -OR-
• Not moving
Answer
• Does not start at the origin• Constant velocity in the positive direction• Away from the origin• Stops for some time• Turns around• Constant velocity in the negative direction• Toward the origin
CHALLENGE QUESTION
(CHALLENGE) Answer
• Slows down in the positive direction• Stops for an instant• Speeds up in the negative direction• Constant velocity in the negative direction• Slows down in the negative direction• Stops for an instant• Speeds up in the positive direction
