a speed graph shows us how the speed of a moving object changes with time

-- 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.
Constant speed is shown on a graph using straight lines. The straight line indicates that there are no fluctuations with the speed.
The slope of a speed/time graph at any point is the acceleration at that instant.
Acceleration=change in y graph/change in x graph
Distance you read off directly from the graph. Speed is the rate of increase of distance, so it is the slope (gradient) of the graph.
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
speed graph
Acceleration is indicated on a speed/time graph.
-- 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 (in the radial direction) = slope of the graph.
No, but the slope of the graph does.
Slope of the graph will give you speed.
Line graph.
If speed changes, then the speed/time graph has up/down curves in it.
No. The slope on a speed vs time graph tells the acceleration.
Acceleration is how fast you get up to speed.
