Velocity
A change in position in a certain amount of time is called motion.
The rate of change of motion is called jerk, jolt, surge, or lurch. The rate of change is derivative of motion with respect to time, velocity, and/or position.
If you are staying in the same position and not moving, then your rate of motion is zero.

If we replace "motion" with a similar term called "velocity", both are rates of change:* Velocity is the rate of change of position (the derivative of the position, with respect to time). * Acceleration is the rate of change of velocity (that makes it the second derivative of the position, with respect to time).
This is velocity.
Almost. speed is (the rate of) the change in position.
Rate of change in position is called velocity.
