Distance and Displacement

Billy runs 400 meters to Andy's house, turns around, and runs 400 meters back home. What is Billy's displacement?

• 0 meters

• 400 meters

• 800 meters

• 1600 meters

From the figure, what is the displacement?

• 20 meters

• 25 meters

• 15 meters

• 25 meters NE

Because displacement has a magnitude and direction it is called a ______. 

• distance

• vector

• arrow

• length

Which of the following is correct?

• Initial Position = -5 m

  Final Position = -5 m

  Distance = 22 m

  Displacement = 0 m

• Initial Position = -5 m

  Final Position = -5 m

  Distance = 0 m

  Displacement = 22 m

• Initial Position = -5 m

  Final Position = 6 m

  Distance = 22 m

  Displacement = 0 m

• Initial Position = -5 m

  Final Position = 6 m

  Distance = 0 m

  Displacement = 22 m

Which of the following is correct?

• Initial Position = -2 m

  Final Position = 0 m

  Distance = 14 m

  Displacement = 2 m

• Initial Position = 0 m

  Final Position = -2 m

  Distance = 14 m

  Displacement = -2 m

• Initial Position = -2 m

  Final Position = 0 m

  Distance = -2 m

  Displacement = -2 m

• Initial Position = -2 m

  Final Position = 0 m

  Distance = 14 m

  Displacement = 14 m

• None are correct.

Object C had an initial position of 2 m and a final position of 10 m. The displacement of object C can be shown with this equation: Displacement = final position - initial position
What was the displacement of object C?

• +6 m

• +8 m

• -4 m

• -2 m
