Describing Motion with Velocity vs. Time Graphs
-The slope of the line on a velocity-time graph reveals useful information about the acceleration of the object.
-If the acceleration is zero, the slope is zero (i.e., a horizontal line).
-If the acceleration is positive, the slope is positive (i.e., an upward sloping line).
-If the acceleration is negative, the slope is negative (i.e., a downward sloping line).
