Question

which of the following statements best describes the objects motion?
velocity (m/s)
+10
0
-10
0 1 2 3 4 5
time (s)
the object is not moving
the object moves with a constant positive velocity
the object moves with a constant negative velocity
the object is speeding up
the object is slowing down

Explanation:

Step1: Analyze the velocity - time graph

The velocity is a constant $v = 10\ m/s$ over time from $t = 0\ s$ to $t=5\ s$.

Step2: Recall motion - related concepts

A non - zero constant velocity means the object is moving with a constant speed in a straight line. Since the velocity value is positive ($v = 10\ m/s$), it is moving with a constant positive velocity.

Answer:

The object moves with a constant positive velocity
