1. Motion Graphing Acceleration vs. Time Graphs
If graph has a SLOPE of ZERO; object has a CONSTANT ACCELERATION and VELOCITY is INCREASING.
MOTION at a constant acceleration.
slope = 0
Vav = increasing
a = constant
acceleration (m/s/s)
time (s)

2. Motion Graphing Acceleration vs. Time Graphs
If intervals between acceleration & time intersection points are same; graph represents object moving with INCREASING ACCELERATION; VELOCITY INCREASING
greater slope = greater acceleration and velocity is increasing
SIGN of slope on an acceleration/time graph indicates CHANGE IN ACCELERATION of object’s travel, or change in DIRECTION of acceleration when below axis
POSITIVE (+) slope indicates increasing acceleration, or change in direction of acceleration when below x-axis
acceleration (m/s/s)
time (s)

3. Motion Graphing Acceleration vs. Time Graphs
If intervals between acceleration & time intersection points are same; graph represents object moving with DECREASING ACCELERATION; VELOCITY DECREASING
greater slope = greater acceleration and velocity is decreasing
SIGN of slope on an acceleration/time graph indicates CHANGE IN ACCELERATION of object’s travel, or change in DIRECTION of acceleration when below x-axis
NEGATIVE (-) slope indicates decreasing acceleration, or change in direction of acceleration when below x-axis
acceleration (m/s/s)
time (s)

4. Motion Graphing Velocity vs. Time Graphs
AREA under curve of a Velocity/Time graph is DISTANCE traveled by object.
Object with initial Constant Velocity
Vav =Dx Dx = VavDt Dt
velocity (m/s)
time (s)

5. Motion Graphing Velocity vs. Time Graphs
AREA under curve of a Velocity/Time graph is DISTANCE traveled by object.
Object from rest, velocity increasing at constant rate
Dx = 1aDt2 2
velocity (m/s)
time (s)

6. Motion Graphing Velocity vs. Time Graphs
AREA under curve of a Velocity/Time graph is DISTANCE traveled by object.
Object with initial speed, velocity increasing at constant rate
Dx = ViDt + 1aDt2 2
velocity (m/s)
time (s)
