It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
The curved line on a time vs. distance graph represents that the object is accelerating.
if the speed is zero then the distance versus time line will be horizontal
a vertical one
Standing still or not moving
The object is accelerating or decelerating in the radial direction.
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.
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
if the speed is zero then the distance versus time line will be horizontal
it is a positive relationship
That means the speed (the slope of the position-time graph) is decreasing.
a vertical one
It is false
no motion
Straight line
Yes it is.
