Question

select the correct answer.

select which two areas of the velocity - time graph is an object moving at a constant speed.
select two correct answers.

velocity - time graph

Explanation:

Step1: Recall speed - velocity relationship

Speed is the magnitude of velocity. Constant speed means the magnitude of velocity does not change.

Step2: Analyze the graph

On a velocity - time graph, a horizontal line segment indicates that the magnitude of velocity (speed) is constant. In the given graph, the segments from \(t = 1\ s\) to \(t = 2\ s\) and from \(t = 3\ s\) to \(t = 4\ s\) are horizontal.

Answer:

The object is moving at a constant speed in the time - intervals \(1 - 2\ s\) and \(3 - 4\ s\)
