instantaneous acceleration* * * * *No it does not.The graph is a distance-time graph so the coordinates of a point on the graph represent the position (distance) at the specified time. The gradient of the tangent to the curve at that point represents the instantaneous radial velocity. The second derivative at that point, if it exists, would represent the acceleration.
The object is accelerating or decelerating in the radial direction.
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
it is a line on a graph that is curved
A bobsled's distance-time graph indicates that it traveled 100 m in 25 s. What is the bobsled's speed
When there is a curved line going upwards on a graph it means the distance is increasing

The gradient of the tangent to the curve at that point represents the instantaneous radial velocity. The second derivative at that point, if it exists, would represent the acceleration.
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 gradient (slope) of the line on the graph.
The object is accelerating or decelerating in the radial direction.
A curved line represents changing speed - either acceleration or deceleration - while a straight line indicates that the speed is constant.
constant speed
The object is accelerating or decelerating in the radial direction.
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
nonlinear line
If the graph of distance traveled vs. time is not a straight line, it indicates that the object's acceleration is not constant. Acceleration is the rate of change of velocity, so a non-linear distance-time graph suggests that the object's velocity is changing at a non-constant rate, causing a curved graph.
