hey,(adsbygoogle = window.adsbygoogle || []).push({});

i am not a physician my self but a programmer and currently i am working on a little program that would calculate the speed of the point.

i have no clue how far is that point going or for how long it will be traveling for.

ok so i have a point (consisting of x and y coordinates)

the point can move in any direction.

can stop and start moving again.

the point can move faster and then slow down(stop) gently or vise-versa .

the distance is unknown.

the travel time is unknown.

the future direction is unknown.

only know factor is the current or previous coordinates of that point.

to make it clearer think of it as a computers mouse cursor. what speed is the mouse cursor moving at when you move it?

is there a formula that could calculate the speed of that point?

any suggestions/links or whatever information will help!! i have been stuck on this for

months....

please when you answer do not use physics terminology i will not be able to understand so try explaining everything like to a child :)

p.s the speed could be anything from meter per second, pixels per millisecond or miles per hour. as long as i have some sort of formula ill apply it i guess ..:)

thank you
