Acceleration is what determines how quickly an Umamusume can increase her Current Speed to match that new Target Speed ...

When an object changes velocity, it accelerates . Acceleration is defined as the rate of change of velocity. Acceleration is the change in velocity per second and is measured in m/s 2 ...

Here's a quick guide explaining two important terms directly affecting your trainee's speed in Umamusume: Pretty Derby.

As acceleration facilitates growth, your scope and scale widen on all fronts. An interesting momentum gain occurs with both increased mass and velocity. Momentum is what keeps you going.
