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 instantaneous slope at any point along the graphed line is the speed at that point in time.
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.
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.

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.
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.
That would depend on the type of axes. If it is an acceleration vs. time graph, then there would be a continual reading of 0m/s/s acceleration, and the graph would be a straight line indicating 0m/s/s at all times. If it is a velocity vs time graph, then there would be a constant value of velocity at all times. If it is a displacement vs time graph, there would be a straight, continuously increasing line.
The object is moving at a constant speed.
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.
The distance versus time graph shows the position of the object. The slope of the line shows the velocity of the object. The velocity is the direction and speed of an object. If your slope has a positive slant that means you are going in a positive direction. If the slope has a negative slant your object is going in a negative direction. If your slope is zero (a horizontal line) that means your object has stopped and is about to change directions. In case you didnt know a positive slant looks like this on a graph.... / a negative slant looks like this on a graph.... \ postive is like sloping up a hill negative is like falling down the hill
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
