The object’s acceleration is increasing constantly.
The object’s acceleration is increasing constantly.
The object’s acceleration is increasing.
The object’s acceleration is increasing.
The object’s velocity is constant.
The object’s velocity is constant.
The object’s velocity is increasing
It's not possible to determine the object's acceleration or velocity based on the graph provided. Additional information is needed to make a conclusion about the object's acceleration or velocity.
Based on the information given, it is not possible to determine the object's velocity or acceleration directly from the graph. The graph only shows the distance traveled over time and does not provide information about velocity or acceleration. Therefore, none of the statements provided can be determined to be true.
To determine which statement is true, we need to analyze the graph that shows an object's distance traveled over a period of time. Here's how you can interpret the graph:
1. Look at the steepness of the line: The slope of the graph represents the object's velocity. If the line is steep, the object is moving quickly. If the line is less steep, the object is moving slowly.
2. Look for changes in the steepness: If the line becomes steeper over time, it means the object is accelerating. Acceleration is the rate at which velocity changes.
3. Look for a constant slope: If the line has a constant slope (neither becoming steeper nor less steep), it means the object's velocity is constant.
Based on these observations, we can determine the true statement:
- If the object's acceleration is increasing constantly, the graph should show a line that becomes steeper and steeper over time. This does not match the description of the graph, so this statement is not true.
- If the object's acceleration is increasing, the graph should also show a line that becomes steeper over time, but not necessarily constantly. Without further information, it is difficult to determine if this statement is true solely based on the graph.
- If the object's velocity is constant, the graph should show a line with a constant slope that is neither becoming steeper nor less steep. If the graph matches this description, then this statement is true.
- If the object's velocity is increasing, the graph should show a line that becomes steeper over time. If the graph matches this description, then this statement is true.
To answer the question, examine the graph and determine if the slope is constant or changing over time. If it is constant, the correct statement is "The object’s velocity is constant." If it is changing and becoming steeper, the correct statement is "The object’s velocity is increasing."

The vehicles have the same velocity, but not the same speed.
The vehicles have the same velocity, but not the same speed.
The vehicles are going in opposite directions, so their speed is not the same.
