The graph below depicts an object's distance
traveled over several intervals of time.
Distance
C
A B Time
(1 point)
E
Which option correctly lists the motion of the
object for each time interval?
interval AB → constant speed
interval BC acceleration
interval CD →→ constant speed
interval DE →→ no motion
interval AB → no motion
interval BC →→ constant speed
interval CD →no motion
interval DE →→→ acceleration
interval AB → no motion
interval BC →→ decreasing speed
O interval CD constant speed
interval DE → acceleration
The correct option is:
interval AB → constant speed
interval BC → acceleration
interval CD → constant speed
interval DE → no motion
The correct option that lists the motion of the object for each time interval is:
interval AB → constant speed
interval BC → acceleration
interval CD → constant speed
interval DE → no motion
To determine the motion of the object for each time interval, we need to analyze the graph and identify the characteristics of the object's movement.
Starting from the left side of the graph:
Interval AB:
- The distance traveled is constant, meaning the object is not moving.
- The answer option "interval AB → no motion" matches this observation.
Interval BC:
- The distance traveled is increasing, indicating that the object is moving.
- Moreover, the distance traveled is increasing at an increasing rate, which suggests acceleration.
- The answer option "interval BC →→ acceleration" matches this observation.
Interval CD:
- The distance traveled remains constant over this interval.
- The answer option "interval CD constant speed" matches this observation.
Interval DE:
- The distance traveled is decreasing, indicating that the object is moving.
- Furthermore, the distance traveled is decreasing at an increasing rate, suggesting acceleration in the opposite direction.
- The answer option "interval DE → acceleration" matches this observation.
Based on the analysis, the correct option would be:
interval AB → no motion
interval BC →→ acceleration
interval CD constant speed
interval DE → acceleration
