The answer is motion
a body is said to be at rest if it does not change its position with time with respect to a reference point
when position of the body with respect to an observer change with time then the body are said to be in motion.
Velocity is the rate of change of position - i.e., the derivative of position with respect to time.Acceleration is the rate of change of velocity - i.e., the second derivative of position with respect to time.
1.There must be a reference point (stationary object ) to describe the position of the given body. 2. The position of the given body must continuously change with time and with respect to the reference point.

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).
Velocity is the derivate of position with respect to time (i.e., the rate of change of position). Velocity is a vector (the direction is relevant). If only the number is specified, not the direction, the word "speed" is used instead. Acceleration is the derivative of velocity with respect to time; or the second derivate of position with respect to time (i.e., the rate of change of velocity).
If the position is graphed vs time, then the slope (rate of change of position with respect to time) will be the same (parallel).
Motion is the process of changing your initial position to a possibly different final position.
acceleration of a body is the rate of change of velocity with respect to time.
When an object changes its position with respect to time, then the body is said ti be in 'motion'. When the body is at rest, it is state of 'no motion'.
