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 (in the radial direction) = slope of the graph.
Yes.
If you graph distance vs. time, the slope of the line will be the average speed.
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
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.
yes, if you mean that speed=distance divided by time, also known as distance/time
speed is the gradient under the distance vs time graph which is change in distance /change in time
The answer depends on whether the graph is that of speed v time or distance v time.
On a graph of acceleration vs. time, during deceleration the line is below zero. On a graph of speed vs. time, during deceleration the line has a negative slope (sloping downward from left to right).
To calculate average speed, you measure how long it takes(T) to get from point A to point B. Then you use the formula below: speed = (B - A)/T
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
