The curved line on a time vs. distance graph represents that the object is accelerating.
When there is a curved line going upwards on a graph it means the distance is increasing
Any curved line on a distance/time graph indicates the presence of accelerationthat's causing a change in the magnituide of the velocity. But if the object's speedis constant, and the acceleration is changing its direction only, then the line on theD-T graph would remain straight.In summary:Every curved line on a D-T graph reveals acceleration, but not every accelerationproduces a curved line on a D-T graph.
if the speed is zero then the distance versus time line will be horizontal
You can show the motion of an object on a line graph in which you plot distance versus time.
it is a positive relationship
-- If the distance-time graph is a straight line, then the magnitude of acceleration is zero. -- If the magnitude of acceleration is not zero, then the distance-time graph is curved.
That means the speed (the slope of the position-time graph) is decreasing.
a vertical one
The slope of a line or a distance-vs-time graph will represent the speed of the object.
It is false
