ORIGINAL: Real0ne The subject matter is NOT how you calculate velocity, or an average, it is 'instantaneous', as in the instantaneous value at a precise point in time, exactly what the definition says, and instantaneous applies to speed, voltage, temperature in precisely the same way. Nice try anyway. AND I did not say the graph I posted was velocity, I said only distance and time. You took it upon yourself to imagine it is velocity, not that it matters since instantaneous velocity does exist, in which case you would use the deltas to calculate the instantaneous velocity. "Instantaneous velocity," like any limit, is defined at a specific value of time t. It is purely logical; it can never be observed or measured. To measure a velocity, it is necessary to know both a distance Δs and a time Δt, however small. A body in motion is in motion during every interval of time in which it moves. That is why it is a derivative value given limits. Why is that so unclear to you? you are severely confused, or a mathematical stooge since there is no derivative in the diagram I posted. Not me who lacks understanding. Nice try, maybe you will get your square peg in that round hole yet! Lame
