Want this question answered?
If you graph distance vs. time, the slope of the line will be the average speed.
Yes.
You can use a graph to calculate speed.
You can calculate speed by taking the gradient (dy/dx) from a Distance-time graph since s=d/t
speed is the gradient under the distance vs time graph which is change in distance /change in time

Speed (in the radial direction) = slope of the graph.
Yes.

If you only have the speed/time graph, you can't calculate force out of it. You could if you also knew the mass of the object that's speeding along, but not with the speed alone.
That's not correct. If you have a graph of distance as a function of time, the speed is the slope of the graph.
speed is the gradient under the distance vs time graph which is change in distance /change in time
the speed
Assuming it's a graph of speed vs time, then between 2 times, the average is the distance (= area under the graph between those times) divided by the time difference.
-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
Speed is distance divided by time so pick the section you want to work out the average for, work out how much distance has been traveled in that section and divide it by how much time has passed for that section.
