Can you calculate speed from a motion graph?

If you graph distance vs. time, the slope of the line will be the average speed.


How do you calculate speed of a distance time graph?

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


Can you calculate the initial speed from speed-time graph?

Yes.


What formula is used to calculate motion?

You can use a graph to calculate speed.


How do you read and calculate speed from a motion graph?

You can calculate speed by taking the gradient (dy/dx) from a Distance-time graph since s=d/t


How do you calculate forse on a speed time graph?

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.


Why area below the distance-time graph is used to calculate speed?

That's not correct. If you have a graph of distance as a function of time, the speed is the slope of the graph.


How can you calculate the speed in a distance time graph?

speed is the gradient under the distance vs time graph which is change in distance /change in time


You can calculate the average speed of an object by?

the speed


How do you do you average speed on a graph?

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.


The relationships between average speed and the slope of a position time graph?

-- 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.


How can you calculate average speed from a distance -time 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.
