Chapter 11 Motion
Section 11.3 Acceleration(pages 342–348)
This section describes the relationships among speed, velocity, and acceleration. Itdiscusses examples of these concepts. It also shows sample calculations ofacceleration and graphs representing accelerated motion.
Reading Strategy (page 342)
Summarizing Read the section on acceleration. Then complete the conceptmap to organize what you know about acceleration. For more information onthis Reading Strategy, see the Reading and Study Skills in the Skills andReference Handbook at the end of your textbook.
What Is Acceleration? (pages 342–345)
1. The rate at which velocity changes is called . 2. Circle the letter for each way an object can accelerate.
a. change in speedb. change in velocityc. change in direction
3. Circle the letter of the correct answer. A horse on a carousel that ismoving at a constant speed is accelerating because .
a. its direction constantly changesb. its speed constantly changesc. its height constantly changes
Calculating Acceleration (pages 345–346)
4. Circle the letter of the equation used to calculate the acceleration of anobject.
a. acceleration = change in velocityb. acceleration = change in velocity/total timec. acceleration = total time/change in velocity

5. Is the following sentence true or false? When the final velocity is lessthan the initial velocity of an object, the acceleration is negative.
Graphs of Accelerated Motion (pages 346–348)
For questions 6 through 9, refer to the graphs below.
6. Graph A represents the motion of a downhill skier. How fast was the
skier moving after traveling down the hill for 2.5 seconds? 7. In which graph does an object move at constant speed during the first
4 seconds? 8. Is the following sentence true or false? If Graph B represents the motion
of a mountain biker, then the biker’s speed at times of 10 s is 5 m/s.
9. Graph B represents the motion of a mountain biker. Determine thebiker’s acceleration during the 10 second to 20 second time period.
Show your work.
Instantaneous Acceleration (page 348)
10. The measure of how fast a velocity is changing at a specific instant isknown as . Circle the correct answer.
a. average accelerationb. constant accelerationc. instantaneous acceleration
