a velocity vs. time graph for an object is shown. which best describes the acceleration of the object? constant and positive constant and negative changing and positive changing and negative velocity vs time

a velocity vs. time graph for an object is shown. which best describes the acceleration of the object? constant and positive constant and negative changing and positive changing and negative velocity vs time

Answer

Explanation:

Step1: Recall acceleration - velocity relation

Acceleration is the slope of the velocity - time graph.

Step2: Analyze the graph

The velocity - time graph is a straight line. A straight - line graph has a constant slope.

Step3: Determine the sign of the slope

As time increases, velocity increases. So the slope (acceleration) is positive.

Answer:

constant and positive
