Multiple Choice

A turtle travels 1 km/hour for 10 hours. The turtle then stops to rest for 2 hours. After that, it continues to travel at 1 km/hour for 4 hours.

The graph shows the motion of the turtle. The graph has four points that mark a change in the speed of the turtle.

Four points on the graph are listed in no particular order.

10 km, 12 hr

10 km, 10 hr

0 km, 0 hr  

14 km, 16 hr

Which is the correct order of the points from left to right on the graph?

• 1, 3, 2, 4

• 2, 4, 1, 3

• 3, 2, 1, 4

• 4, 2, 3, 1

Poll

Analyze Which of these two statements is correct?

• Newton’s First Law of Motion
  is really two laws, because
  putting a stationary body
  into motion is different
  from changing the motion
  of a moving object.
