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:

To determine which objects are slowing down, we analyze the velocity - time graphs:

Graph 1:

The velocity starts from a negative value (below the time axis) and moves towards zero as time increases. When an object's velocity is moving towards zero (regardless of the initial sign of velocity), if the velocity has a non - zero magnitude and is approaching zero, the object is slowing down. In this case, the speed (magnitude of velocity) is decreasing as it gets closer to zero.

Graph 2:

The velocity starts at zero and moves into the negative region (more negative) as time increases. The magnitude of the velocity is increasing (since it is moving away from zero in the negative direction). So, the object is speeding up (in the negative direction), not slowing down.

Graph 3:

The velocity starts from a positive value and moves towards zero as time increases. The magnitude of the velocity (speed) is decreasing as it approaches zero. So, the object is slowing down.

Answer:

The first and the third velocity - time graphs (the graphs where velocity approaches zero, with the first having velocity starting negative and moving to zero, and the third having velocity starting positive and moving to zero) represent objects that are slowing down. If we consider the graphs as Graph A (first), Graph B (second), Graph C (third), the answer is Graph A and Graph C.
