I currently have a machine that can calculate the time it takes for an object to travel one meter. (two lasers first one starts a timer second one stops it, The lasers are positioned exactly 1 meter apart.)
So if an object was going 10 M/s (Meters per second) it would take 0.1 of a second (10 nanoseconds) to travel one meter. If it was going 1 meter per second it would take 1 second, obviously.
What would the equation needed to turn the time taken into the speed (In Meters per second preferably)
For those interested the program used is called Algodoo
