Motion can involve speed and/or direction change {acceleration}|. Acceleration has amount and direction, so acceleration is vector. Acceleration a is velocity change dv divided by time change dt: a = dv / dt. Gravity acceleration g is 9.8 meters per second per second: g = 9.8 m/s^2.
Acceleration can change over time {jerk}|: j = da/dt.
Jerk can change over time {jounce} {snap}: dj/dt.
