Question

the velocity - time graphs represent the motion of three different objects. identify any object that is getting slower or slowing down. tap on all that apply. tap to select or deselect graphs.

Explanation:

Step1: Understand slowing - down in v - t graph

In a velocity - time graph, an object is slowing down when the magnitude of velocity is decreasing over time. This means the slope of the graph is negative (for non - constant velocity cases) or the velocity values are getting closer to zero.

Step2: Analyze first graph

The first graph has a negative slope. As time increases, the velocity (starting from zero and going in the negative direction) is decreasing in magnitude (getting closer to zero from the negative side), so the object is slowing down.

Step3: Analyze second graph

The second graph has a positive slope. As time increases, the velocity (starting from a negative value and going towards a positive value) is increasing in magnitude, so the object is speeding up, not slowing down.

Step4: Analyze third graph

The third graph has a negative slope. As time increases, the velocity (starting from a positive value) is decreasing in magnitude (getting closer to zero), so the object is slowing down.

Answer:

The first and the third graphs represent objects that are slowing down.
