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 (Left - hand side)

• The velocity of the object is negative (below the time axis) and its magnitude is increasing (the graph is going further down from zero). This means the object is speeding up in the negative direction, not slowing down.

Graph 2 (Middle)

• The velocity of the object is negative (below the time axis) and it is approaching zero (the graph is moving towards the time axis from the negative side). When an object has a negative velocity and is moving towards zero velocity, its speed (the magnitude of velocity) is decreasing. So this object is slowing down.

Graph 3 (Right - hand side)

• The velocity of the object is positive (above the time axis) and it is approaching zero (the graph is moving towards the time axis from the positive side). When an object has a positive velocity and is moving towards zero velocity, its speed (the magnitude of velocity) is decreasing. So this object is also slowing down.

So the objects represented by the middle and the right - hand side graphs are slowing down. If we assume the graphs are labeled as Graph A (left), Graph B (middle), Graph C (right), the answer is Graph B and Graph C.
