How do you calculate speed of a distance time graph?

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


Can you calculate speed from a motion graph?

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


A ball is thrown straight up with an initial speed of 20 m calculate its initial speed take g10 ms-2?

Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!


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


How do you calculate initial speed without time given?

distance divided by speed is equal to timetraveled.


How do you calculate speed without distance?

If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.


True or false To calculate the acceleration of and automobile you must first subtract the final speed from the initial speed?

True


How do you calculate initial velocity given only the initial position and the scale of the horizontal and vertical axes?

We suspect that you're also given a line on the graph. If so, then the initial speed is the slope of the line at the initial position. To get the real slope of the line, you need to know the scales of the axes. If the scales aren't the same, then the real slope of the line isn't what it looks like, and has to be calculated by measuring its progress along both axes just after the initial position.
