Suppose that an object travels from one point in space to another. Make a comparison between the displacement and the distance traveled.

A) The displacement is either greater than or equal to the distance traveled.

B) The displacement is always equal to the distance traveled.

C) The displacement is either less than or equal to the distance traveled.

D) The displacement can be either greater than, smaller than, or equal to the distance traveled.

E) If the displacement is equal to zero, then the distance traveled will also equal zero.

Which statement below about the distance between the starting and ending positions and the displacement between the starting and ending positions is correct?

A) The distance between the starting and ending positions is twice the magnitude of the displacement between the starting and ending positions.

B) The distance between the starting and ending positions is equal to the magnitude of the displacement between the starting and ending positions.

C) The distance between the starting and ending positions is the negative of the magnitude of the displacement between the starting and ending positions.

D) The distance between the starting and ending positions is greater than the magnitude of the displacement between the starting and ending positions.

E) The distance between the starting and ending positions is less than the magnitude of the displacement between the starting and ending positions.
