Question

the velocity - time graphs represent the motion of four different objects. identify any object that is moving in the - direction and slowing down. tap on all that apply. tap to select or deselect graphs.

Explanation:

Step1: Understand motion concepts

In velocity - time graphs, negative velocity means moving in the negative direction. A negative slope means slowing down (decelerating).

Step2: Analyze each graph

1. For the top - left graph: Velocity is positive, so it's moving in the positive direction.
2. For the top - right graph: Velocity is negative (below the time - axis) and the slope is negative (line is sloping downwards), so the object is moving in the negative direction and slowing down.
3. For the bottom - left graph: Velocity is negative and slope is positive, so it's moving in the negative direction but speeding up.
4. For the bottom - right graph: Velocity is negative and the curve has a negative slope (getting less negative), so it's moving in the negative direction and slowing down.

Answer:

The top - right and bottom - right graphs represent objects moving in the negative direction and slowing down.
