WebHow is velocity measured? There are a number of ways you can measure velocity (from story points to a “number of items completed” approach, etc.) Though velocity is often expressed in “points”, it isn’t needed to measure in points (velocity is simply how much stuff you have done in whichever way you want to measure it) Web4,665 5 39 68. You need a frame of reference to measure velocity. It doesn't mean anything without a frame. Please try to be more precise--- I have a rock floating through space, and a spaceship, and I want to measure the velocity of the rock relative to the spaceship. You can do this by bouncing light off it and measuring the Doppler shift.

WebSep 17, 2024 · All you need to do is pick a value for t and plug it into your derivative equation. For example, if we want to find the instantaneous velocity at t = 5, we would just substitute "5" for t in the derivative ds/dt = -3 + 10. Then, we'd just solve the equation like this: ds/dt = -3t + 10. ds/dt = -3 (5) + 10.
