If it is a horizontal straight line, it means the object is moving at constant velocity. If it is a sloped line, it means the object is accelerating.
The graph is a straight line. Its slope is the speed.
The straight horizontal line on the graph says: "Whatever time you look at, the speed is always the same". This is the graph of an object moving with constant speed.
straight line
A straight line with a positive slope on a position-time graph is the graph of an object that's moving in a straight line with constant speed.
For motion at constant speed along a straight line, the acceleration is zero.
Constant speed is shown on a graph using straight lines. The straight line indicates that there are no fluctuations with the speed.
The graph is a straight line. Its slope is the speed.
The straight horizontal line on the graph says: "Whatever time you look at, the speed is always the same". This is the graph of an object moving with constant speed.
-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.
straight line
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
A straight line with a positive slope on a position-time graph is the graph of an object that's moving in a straight line with constant speed.
On a graph of velocity and time, a constant speed would appear as a straight horizontal line.
For motion at constant speed along a straight line, the acceleration is zero.
a sloped straight line
A graph that shows speed versus time is not an acceleration graph.The slope of the graph at any point is the acceleration at that time.A straight line shows that the acceleration is constant.
