The shape and slope of the line on a graph illustrates the qualitative and quantitative
relationship between the variables plotted on the axes of the graph.
Sadly, there is no such graph as a "speed or time" one.
yes
as a horizontal straight line
if the speed is zero then the distance versus time line will be horizontal
A horizontal line on a speed vs time graph indicates constant speed.
No. The slope on a speed vs time graph tells the acceleration.
yes
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.
as a horizontal straight line
If the line formed by the graph is straight, the speed is constant. A horizontal line would show the object as stationary.
-- 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.
Speed = distance / time A line graph with distance on the vertical axis and time on the horizontal axis could be used to determine speed. The speed would equal the slope of the line. Alternatively, a line graph with distance/time on the vertical axis and time on the horizontal axis would show speed. The acceleration would equal the slope of the line.
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
On a graph of acceleration vs. time, during deceleration the line is below zero. On a graph of speed vs. time, during deceleration the line has a negative slope (sloping downward from left to right).
if the speed is zero then the distance versus time line will be horizontal
A horizontal line on a speed vs time graph indicates constant speed.
No. The slope on a speed vs time graph tells the acceleration.
it will never be a vertical line as the slope is velocity and that would be infinite speed
