How can you tell motion occurs?

• The object's speed decreases in regards to the reference point.

• The object and the reference point both move at the same speed.

• The object's speed increases in regards to a reference point.

• The object's position changes in regards to a reference point.

A softball player leaves the batter's box, overruns first base by 3.0 meters, and then returns to first base. Compared to the total distance traveled by the player, the player's displacement from the batter's box is:

• smaller

• larger

• the same as

Which of the following is correct?

• Initial Position = 0 m

  Final Position = 6 m

  Distance = 6 m

  Displacement = 6 m

• Initial Position = 6 m

  Final Position = 0 m

  Distance = 6 m

  Displacement = 6 m

• Initial Position = 6 m

  Final Position = 6 m

  Distance = 6 m

  Displacement = 6 m

• Initial Position = 0 m

  Final Position = 6 m

  Distance = 0 m

  Displacement = 6 m

• None are correct.

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.

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
