Speed
Time
The graph above shows an object's motion. Which
statement is true?
(1 point)
The object does not move.
The object accelerates at an increasing rate
followed by a decreasing rate.
The object starts at rest and then accelerates at
a constant rate.
The object accelerates at an increasing rate.
The object starts at rest and then accelerates at a constant rate.
Based on the information provided, the correct statement is:
"The object starts at rest and then accelerates at a constant rate."
To determine which statement is true based on the graph shown, you need to understand the relationship between speed and time. The speed of an object can be determined by looking at the slope of the line on the graph.
If the speed of the object remains constant, the graph would show a straight, horizontal line indicating that the object is not accelerating or decelerating.
If the speed of an object is increasing, the graph would show an upward sloping line, indicating that the object is accelerating.
If the speed of an object is decreasing, the graph would show a downward sloping line, indicating that the object is decelerating.
Based on the given graph, we can observe that the line starts from a resting position and then slopes upward, indicating that the speed of the object is increasing. Therefore, the correct statement is: "The object starts at rest and then accelerates at a constant rate."
