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

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

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
