Question

select the statement(s) that accurately describe the distance - time graph shown. after the object starts moving, it stops moving for a period of time. the object begins moving at a constant speed. after the object stops moving, it moves at a faster, constant speed than before. the object was moving and slowed down. after the object stops

Explanation:

In a distance - time graph, a horizontal line indicates the object is not moving (constant distance over time means zero speed). A straight non - horizontal line indicates constant speed. A steeper non - horizontal line after a flatter one means a faster constant speed. If the line is getting less steep, the object is slowing down.

1. If there is a horizontal section after a non - horizontal section, the object stops moving for a period of time after starting to move.
2. A straight non - horizontal initial section means the object starts moving at a constant speed.
3. If there is a steeper non - horizontal section after a horizontal one, the object moves at a faster constant speed after stopping.
4. There is no indication of the object slowing down as there is no section where the slope is decreasing.

Answer:

A. After the object starts moving, it stops moving for a period of time.
B. The object begins moving at a constant speed.
C. After the object stops moving, it moves at a faster, constant speed than before.
