1. Motion Table of Contents Describing Motion Speed and Velocity
Acceleration

2. Describing Motion Nicolaus Copernicus
In 1543 Copernicus published On the Revolution of the Heavenly Spheres, a book based on his 30-year study of the solar system.

3. Speed and Velocity
Use the data from all three legs to solve for each triathlete’s average speed.

4. Speed and Velocity
Constant Speed
What is the jogger's speed?

5. Speed and Velocity Changing Speed
The graph shows how the speed of a jogger varies during her second day of training. What are the rise, the run, and the slope for each segment of the graph?

6. Acceleration Acceleration
The airplane is accelerating at a rate of 8 m/s2. Determine the speed of the airplane at 4.0 s and 5.0 s.
0 m/s
8 m/s
16 m/s
24 m/s

7. Acceleration Deceleration
The airplane touches down with a speed of 70 m/s. It decelerates at a rate of -5 m/s². Determine its speed after each second of its deceleration.

8. Acceleration Speed-Versus-Time Graph
Use the time and speed data in the table to plot a line graph. Plot time on the horizontal axis. Plot speed on the vertical axis. What would be a good title for the graph?

9. Acceleration Distance-Versus-Time Graph
Use the time and distance data in the table to plot a line graph. Plot time on the horizontal axis. Plot distance on the vertical axis. What would be a good title for the graph?
