Question

Deena made a chart to summarize features of a velocity vs. time graph for objects with constant acceleration and objects with constant velocity. Which best describes Deena’s error?
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 line.

Answer 1

The error is:
"Find acceleration by finding the area of the rectangle above the line"

The acceleration of any body is the rate of change of velocity of that body. If the motion of the object being considered is plotted on a graph, with the velocity on the y-axis and the time on the x-axis, this ratio will be equivalent to the slope of the graph, not the area above the line.

Answer 2

Answer:

Include the area of the rectangle under the line to find displacement for constant acceleration.
