Walk this way!

1. Walk this way!

2. 1. Starting at the motion detector, Fatima walks away slowly. D(m) T(s)

3. D(m) T(s) 2. Starting at the motion detector, Dameon walks away quickly. The steeper the line, the faster the object is moving. (Less time to cover the same distance)

4. D(m) T(s) 3. Mary starts 4m away from the motion detector, starts walking slowly for 5 s, then stops. Horizontal lines usually mean the object is stopped. (The distance isn’t changing)

5. D(m) 4. Beginning 4m from the motion detector, Tia walks toward it for 3s. She then stops for 5s and then runs back to her starting position. T(s)

6. D(m) T(s) 5. Umar slowly walks away from the motion detector until he is 5m away, and then slowly walks back toward the motion detector.

7. 6. Anthony runs away from the motion detector for 3 s. He stops for 4s, then walks back toward the motion detector. D(m) T(s)

8. D(m) T(s) 7. Standing 2m from the motion detector, Ayesha jumps up and down. What would it look like if the person was circling around the CBR? (same as above)

9. D(m) T(s) 8. Beginning 1m from the motion detector, Bryanna slowly walks away. She then stops for 3s before continuing to walk away, but at a faster pace.

10. D(m) T(s) What would the graph look like if a person was speeding up? Slowing down?
