Question

Which best describes deena’s error? the line for constant velocity is not horizontal; it is diagonal and slopes downward. the area of the rectangle and the triangle under the line should be added together 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 statement best describes deena's error is: Find acceleration by finding the area of the rectangle above the line.

What is acceleration?

Acceleration is given by the ratio of Resultant or total force acting on any object and the its mass.

Deena made a chart to summarize features of a velocity vs. time graph for objects with constant acceleration and objects with constant velocity.

In the  velocity time graph, the area under the curve shows the displacement of the object and the slope represents the acceleration.

Thus, the deena's error is  Find acceleration by finding the area of the rectangle above the line.
