Question

question 8 (3 points) (01.09 lc) motion can be modeled with ticker tape diagrams. equally spaced dots on a ticker tape represents an object a at rest b slowing down c speeding up d moving at constant speed

Explanation:

To determine the correct answer, we analyze the concept of ticker tape diagrams in physics. In a ticker tape diagram, the distance between dots represents the object's displacement during equal time intervals (since the ticker marks at regular time intervals).

• Option a: If an object is at rest, there would be no separation between dots (or very close together, with no change in position), so equally spaced dots do not represent rest.
• Option b: If an object is slowing down, the distance between consecutive dots would decrease over time (since velocity is decreasing, displacement in equal time intervals decreases).
• Option c: If an object is speeding up, the distance between consecutive dots would increase over time (since velocity is increasing, displacement in equal time intervals increases).
• Option d: If an object is moving at constant speed, its displacement in equal time intervals is constant. This means the distance between consecutive dots (which represent displacement over equal time) will be equal (equally spaced).

So, equally spaced dots on a ticker tape represent an object moving at constant speed.

Answer:

d. moving at constant speed
