Worksheet 1- Graphs and Motion Maps



Worksheet 2- Data and Graphing

1. Chaz is rollerblading down a marked sidewalk, and was observed to be at the following positions at the following times.

|Time (S) |X (m) |

|0 |10.0 |

|1 |12.0 |

|2 |14.0 |

|5 |20.0 |

|8 |26.0 |

|10 |30.0 |

a. Plot the position vs. time for the skater. Use the space above to create the graph.

b. How far from the skater’s starting position was he at 6 seconds? How do you know?

c. Write the equation that represents the graph you created.

d. Was his speed constant over the entire time interval? How do you know?

2. Another skater, Mitsy, was observed and the following data was recorded.

|Time (S) |X (m) |

|0 |4 |

|2 |10.0 |

|4 |16.0 |

|6 |22.0 |

|8 |28.0 |

|10 |34.0 |

a. Plot the position vs. time for this skater. Use the space above to create your graph.

b. How far from the skater’s starting position was she at 5 seconds? How do you know?

c. Was her speed constant? If so, what was it?

d. In looking at the data, Chaz is further along at 2 seconds than Mitsy. Does this mean he was going faster? Explain.

3. Suppose a 3rd skater is observed, and the following data is recorded.

|Time (S) |X (m) |

|0 |0.0 |

|2 |6.0 |

|4 |12.0 |

|6 |12.0 |

|8 |8.0 |

|10 |4.0 |

|12 |0.0 |

a. Plot the position vs. time graph for the 3rd skater. Use the space above to create your graph.

b. What do you think is happening between 4 and 6 seconds? Explain.

c. What do you think is happening between 6 and 12 seconds? Explain.

d. Determine the skater’s average speed between 0 and 12 seconds.

e. Determine the skater’s average velocity between 0 and 12 seconds.
