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 velocity - time graph properties

In a velocity - time graph, positive velocity means motion in the positive direction and negative velocity means motion in the negative direction. A negative slope indicates deceleration (slowing down).

Step2: Analyze each graph

• For the first graph (top - left): Velocity is negative and increasing in magnitude (becoming more negative), so it's accelerating in the negative direction.
• For the second graph (top - right): Velocity is negative and decreasing in magnitude (becoming less negative), so it's moving in the negative direction and slowing down.
• For the third graph (bottom - left): Velocity is positive and decreasing, so it's moving in the positive direction and slowing down.
• For the fourth graph (bottom - right): Velocity is positive and increasing, so it's accelerating in the positive direction.

Answer:

The second graph (top - right) and the third graph (bottom - left)
