Steady acceleration is shown by a line sloping up. Assuming typical Galactic velocities of 200–300 km/s (roughly 0.1% the speed of light), the authors estimate that spectra would need to be acquired with an energy precision of 0.1% to distinguish a dark matter source from ordinary gas. The field of physics comes with its own unique set of knowledge. Notice that the formula contains ∆ (delta) symbols and yet I added the distances in the numerator and the times in the denominator. Steady velocity is shown by a horizontal line. It’s the same as the conventional idea of speed: Speed is distance divided by time, which is what a speedometer measures.The related term velocity refers to a speed with an associated direction.To measure velocity, you might use a speedometer in combination with a compass.
