Question

Three objects move and their velocity vs time graphs are shown below

The following questions refer to the velocity vs time graphs above.

1.Are any of the graphs shown representing objects that are slowing down?

2.Do any of the objects have a negative acceleration? How can you tell?

3.Which object’s motion(s) most likely is/are experiencing air resistance? Explain your reasoning.

4.Sketch what the acceleration vs time graphs would look like for each of the velocity graphs.

Answer 1

Here ,

1) No, as for all the graphs, velocity is increasing

2)
there is no negative acceleration , as the velocity is not decreasing

3)

for the object A , as the velocity is maximum for object A

4)

for the acceleration of the graphs
