Which describes where Manny most likely walked?

• from the bottom of a hill to the top

• on a circular nature trail

• on a sidewalk from his house to the mall

• from the beginning of a straight track to the end

Which scenario best describes motion?

• a toy train in position 4 on a number line

• a race track that is 100 meters long

• a ball rolling from point A to point B

• a student living 150 miles from Chicago

Which scenario best describes an object with a displacement of zero?

• A train moves uphill as it travels in a straight path.
