1.) Worksheet - Dispacement-time graphs
The worksheet for this exercise consists of three small and one large displacement-time graph.
Complete the three small displacement-time graphs from the information provided below each graph.
The larger displacement-time graph shows the motion of some hypothetical object over time. Break the
graph up into segments and describe qualitatively the motion of the object in each segment. Whenever
possible, calculate the velocity of the object as well.
Answer – 0 - 6 seconds = uniform motion forward from 0 - 17.5 m.
.
2.92
6 – 9 seconds = object is stopped.
9 - 15 seconds = uniform motion forward from 17.5 – 27.0 m.
. .
1.58
15 - 18 seconds = stopped.
18 – 25 seconds = uniform motion backwards from 27 – 13 m.
1.75
25 – 30 seconds = stopped.
30 – 45 seconds = accelerating forward.
45 – 55 seconds = decelerating forward from 27 – 17 m and stopping.
2.) Worksheet – Velocity-time graphs
The worksheet for this exercise consists of three small and one large velocity-time graph.
Complete the three small velocity-time graphs from the information provided below each graph.
The larger velocity-time graph shows the motion of some hypothetical object over time. Break the graph
up into segments and describe qualitatively the motion of the object in each segment. Whenever possible,
calculate the acceleration of the object as well.
Answer – 0 - 6 seconds = uniform acceleration forward from 0 - 17.5 m.
.
6 – 9 seconds = constant speed of 17.5 m/s.
0
9 - 15 seconds = uniform acceleration forward from 17.5 – 27.0 m.
15 - 18 seconds = constant speed of 27.0 m/s.
0
18 – 25 seconds = uniform deceleration forward from 27 – 13 m.
25 – 30 seconds = constant speed of 13.0 m/s.

30 – 45 seconds = accelerating forward (not uniform).
45 – 55 seconds = decelerating forward (not uniform) from 27 – 17 m and continuing at 18 m/s.
