Motion at a constant speed - no acceleration or deceleration.
The steepness of the line on a distance-time graph represents the radial speed of the object. That is, the speed with which the object is moving towards or away from the origin. The steepness takes absolutely no account of the transverse speed, so you can be going around the origin in a circle at a great speed but, since your distance remains the same, the D-T graph will be flat: implying speed = 0.
A horizontal line on a speed vs time graph indicates constant speed.
Line graph.
A straight line.
If its slanted up its accelerating, if down its decelerating.
A flat line would indicate a constant velocity, no change in speed.
The gradient (slope) of the line on the graph.
That the object is moving at a constant speed

i dont think you can use a line graph for that. i think a table would be better...
it means the object is moving at a constant speed
A straight line with a positive slope could represent the velocity versus time graph of a motorcycle whose speed is increasing.
-- If the graph displays speed against time, then speed of zero is indicated wherever the graph-line touches the x-axis. -- If the graph displays distance against time, then speed of zero is indicated wherever the graph-line is horizontal. -- If the graph displays acceleration (magnitude) against time, then the graph can tell you when speed is increasing or decreasing, but it doesn't show what the actual speed is.
The flat line tells us that the object is moving at a constant velocity. It has zero acceleration.
it depends on what the graph is. if it is a distance vs time graph, the line will be a line with the slope being the speed/total time if it is a speed vs. time graph, the line will be horizontal at y=the speed if it is an acceleration vs time graph, the line will be horizontal at y=0
If the graph if speed vs. time is a straight line parallel to the time axis, then the speed is not changing.Acceleration is the slope of the line on such a graph. Slope is (speed change) divided by (time for the change).Since the speed doesn't change over any period of time, the slope of the line is zero.The object's speed is constant. Its acceleration is zero.
