Acceleration is the term for how fast something’s velocity changes. Again, this can be a change in magnitude or direction. Acceleration is a key component in martial arts. If someone is fast, but fast all the time, then the opponent will be able to time them. If someone can change their speed or direction quickly, then they will be very difficult to beat.

• Acceleration [m/s2] = Change in velocity over time. A=dV/dt

In order to find an object’s velocity, we can integrate the acceleration over time. We can integrate again (the velocity) to find an object’s position.
