Hello. This question is incomplete. The full question is:
"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:
ball rolling from point A to point B
Step-by-step explanation:
We define movement when a body changes its position in relation to a reference point during a certain period of time. Every moving body can be called mobile.
In other words, movement, for physics, only occurs when a mobile body travels a certain distance over a certain period of time. In this case, we can say that an example of movement occurs when a ball rolls from point A to point B.
