Velocity-time graphs test questions

1

What does a horizontal line on a speed-time graph indicate?

2

What does the speed-time graph below represent the object as?

Speed time graph. Line rises from origin sharply before levelling out and remaining so.

3

What is the area under a speed-time graph equal to?

4

Using the graph, calculate the total distance travelled by the motor cycle.

Speed time graph. Line rises from origin to 25m s-1 at 20s, constant until 50s and drops to 0m s-1 at 60s.

5

What is the slope of a line on a velocity time graph an indication of?

6

Speed time graph. Line goes from 10 m/s at 0 sec to -20 m/s after 10 sec.

In the velocity time graph above, what does the section of the graph below the time axis refers to?

7

Speed time graph. Line goes from 12 m/s at 0 sec to -20 m/s after 30 sec with points plotted at 5, 10, 15, 20 and 25 secs.
