Position  Time Diagrams
 How many seconds has elapsed in diagram 1? _________________
 How far did the object travel from the origin? _________________
 What is the distance traveled? _________________

Complete this table for each time segment in diagram 1:
Beginning time  Ending time Time interval Distance traveled in this interval Speed 0 to 2 secs 2 to 3 secs 3 to 4 secs 4 to 5 secs 5 to 8 secs 8 to 10 secs 0 to 10 secs  Use the first six speed values from the table above, add them together and divide by six. Show your calculations. Record that number here ______________.
 What does that number represent?
 Why doesn't that number equal the last (7^{th}) speed calculation in the table?
 How many seconds has elapsed in diagram 2? _________________
 How far did the object travel from the origin? _________________
 What is the distance traveled? _________________

Complete this table for each time segment in diagram 2:
Beginning time  Ending time Time interval Distance traveled in this interval Speed 0 to 2 secs 2 to 4 secs 0 to 4 secs 4 to 9 secs  Sketch a Positiontime diagram showing the path of two objects. One object is moving at twice the speed of the other object.
