  2. Constant speed is the same thing as average speed. • Velocity is another name for speed. • 2 • Speed and Velocity

  3. 2 Speed and Velocity What is speed? How can you use a distance-time graph to calculate average speed? What are ways velocity can change?

  4. speed • constant speed • instantaneous speed • average speed • velocity • 2 • Speed and Velocity

  5. 2 Speed and Velocity How Fast? Look at the photo at the beginning of the lesson. When you hear the word cheetah, you might think of how fast a cheetah can run. As the fastest land animal on Earth, it can reach a speed of 30 m/s for a short period of time. Other than how fast it runs, how might you describe the motion of a cheetah?

  7. Constant speed is the same thing as average speed. 2 Speed and Velocity Disagree. Speed that does not change over time is constant speed. Average speed is the total distance traveled divided by the total time taken to travel that distance.

  8. Velocity is another name for speed. 2 Speed and Velocity Disagree. Velocity includes both speed and direction.

  9. What is speed? 2 Speed and Velocity Speed is the distance an object moves in a unit of time.

  10. How can you use a distance-time graph to calculate average speed? 2 Speed and Velocity You can calculate an object’s average speed from a distance-time graph by dividing the distance the object travels by the total time it takes to travel that distance.

  11. What are ways velocity can change? 2 Speed and Velocity Velocity changes when speed, direction, or both speed and direction change.
