Question

which graphs show an object that is stopped for at least a portion of the time? select all that apply

Explanation:

Step1: Recall motion - graph relationship

In a distance - time graph, a horizontal line represents zero velocity (object is stopped) because the distance is not changing with time.

Step2: Analyze each graph

• For the first graph (top - left), it has a non - horizontal line, so the object is moving throughout.
• For the second graph (top - right), it has a horizontal portion where the distance does not change with time, so the object is stopped for that portion.
• For the third graph (bottom - left), it has a non - horizontal line, so the object is moving throughout.
• For the fourth graph (bottom - right), it is a horizontal line throughout, so the object is stopped for the entire time shown.

Answer:

The second and fourth graphs.
