Questions (use evidence from the graph)1. What was the length of the race?2. What was the hare doing from 6 min until 71
minutes? How do you know?3. How much time did the Hare sleep for? At what
position was he sleeping?4. Who was traveling faster in the beginning of the
race? Cite specific evidence from the graph. 5. When the hare went for sleep, what was the
position of the tortoise? What was the position of the hare at this time?
6. At what time did the tortoise cross over the hare?7. When the tortoise reached the destination, where
was the hare?

When the displacement isnegative, the object has a
position to the left of the origin1 – 2 and 4 – 5 seconds
Constant displacement means thatthe object doesn�t move
The object�s final position isat +1 meter (1 meter to the
right of the origin)
During what time interval(s) was the object to the left of the origin?During what time interval(s) was the object NOT MOVING?At what distance from the origin does the object stop?
