Answer

Brief Explanations:

Displacement is the straight - line distance from the initial to the final position. When the initial and final positions are the same, displacement is zero. In the case of riding on a Ferris wheel with the same entrance and exit, walking around the block starting and ending at the same house, and running one lap around a racetrack, the starting and ending points are identical. In traveling south then west, and riding an escalator from bottom to top, the starting and ending points are different.

Answer:

  • riding on a Ferris wheel whose entrance and exit are the same
  • walking around the block, starting from and ending at the same house
  • running exactly one lap around a racetrack
