Deena made a chart to summarize features of a velocity vs time graph for objects with constant acceleration and objects
with constant velocity
Constant Velocity
the line is horizontal
find displacement using the area of the
rectangle under the line only
Constant Acceleration
the line is diagonal and straight
find displacement by subtracting the area
of the triangle from the area of the
rectangle under the line
find acceleration by finding the slope of
the line
Which best describes Deena's error?
find velocity by locating the values
plotted on the y-axis

The line for constant velocity is not horizontal; it is diagonal and slopes downward
Include the area of the rectangle under the line to find displacement for constant acceleration
Find acceleration by finding the area of the rectangle above the line
Find velocity by calculating the slope of the
