If speed changes, then the speed/time graph has up/down curves in it.
If a body is moving with variable speed, then the only thing you can say aboutits speed/time graph is that the graph is not a straight, horizontal line.
The graph of the motion of a body falling vertically that reaches a terminal speed would show an initial acceleration until the body reaches its terminal velocity. At this point, the graph would level off, showing constant velocity as the body falls continuously.
To determine the speed of a body from a distance-time graph when the body starts from rest, you can find the slope of the graph. The slope of a distance-time graph represents the speed of the body. A steeper slope indicates a higher speed, while a shallower slope indicates a lower speed.
To get speed from a distance-time graph, you would calculate the slope of the graph at a given point, as the gradient represents speed. To calculate total distance covered, you would find the total area under the graph, as this represents the total distance traveled over time.
The shape of the speed-time graph for an object moving with variable speed would depend on how its speed changes over time. It could be linear if the speed changes at a constant rate (acceleration or deceleration), curved if the acceleration is not constant, or a combination of different shapes if the speed fluctuates.
The displacement-time graph for a body moving in a straight line with uniformly increasing speed would be a straight line with a positive slope. As time increases, the displacement of the body also increases at a constant rate.

It is not possible to sketch anything using this browser. The speed of a body cannot be determined from a distance-time graph. The slope of the graph is a measure of the radial velocity - that is the speed directly towards or directly away from the starting point. However, there is absolutely no information of any motion in a transverse direction. Since motion in this direction cannot be assumed to be 0, the distance-time graph cannot be used to determine speed.
If the distance-time graph is a straight line with a constant angle with the time axis, it indicates that the body is moving with a constant speed. The slope of the line represents the speed of the body.
If speed is constant, the graph would be a straight line with a constant slope, indicating that the object is moving at a constant rate without acceleration or deceleration. The distance covered would increase linearly with time.
BecAuse that would mean it is going an infinite speed. The slope of a distance time graph is the objects velocity or speed. If there is a line parallel to the distance axis, there is a vertical line. The slope of a vertical line is infinite. It is not possible to go an infinite speed.
velocitymy answer isIt may be both speed/velocity.We can find acceleration from speed vs time graph when the path followed by the body is a perfect straight line and when the speed of body goes on incresing and in all othercases velocity time graph is used to measure aceleration.
