The speed of an object over time is shown in the graph.



Speed versus time. Time, seconds. Speed, meters per second.



Which table describes the object’s motion?

time interval, seconds. description of the motion. zero through 3. the object's speed is increasing. 3 through 18. the object is at rest. 18 through 23. the object's speed is decreasing.

time interval, seconds. description of the motion. zero through 3. the object is moving in a positive direction. 3 through 18. the object is at rest. 18 through 23. the object is moving in a negative direction.

Time interval, seconds. Description of the motion. zero through 3. the object's speed is increasing. 3 through 18. the object's speed is constant. 18 through 23. the object's speed is decreasing.

time interval, seconds. description of the motion. zero through 3. the object is moving at a constant speed. 3 through 18. the object is at rest. 18 through 23. the object is moving at a constant speed.
