Question

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

Answer 1

The scenario that best describes motion is "a ball rolling from point A to point B." This scenario involves a change in position over time, which is the essence of motion. The other scenarios (toy train in position 4, race track length, student's distance from Chicago) do not explicitly involve any change in position or movement.
