When a body does not change its position with respect to its surroundings, it is said to be at rest.
The answer is motion
A change in position of a body with respect to time is referred to as displacement. It is a vector quantity that describes the magnitude and direction of the change in position of an object in motion. Displacement is a key concept in physics and is typically represented using symbols like ∆x or Δr.
When the body is at rest, it means that it is not exerting any physical effort and is in a state of relaxation. This typically involves minimal movement and reduced energy expenditure. Rest is important for allowing the body to recover and recharge.
MOTION: A body is said to be in motion if it changes it's position with respect to it's surrounding. REST: A body is said to be in rest if it does not changes it's position with respect to it's surrounding.
The description provided suggests that the concept being referenced is velocity, which is the rate of change of position with respect to time. Velocity is a vector quantity that includes both speed and direction of movement.

A body is in motion if it change its position relative to another body or with respect to a frame of reference or coordinate system.
One Direction ==================== Your question is irrelevant as it describes a state of a substance. It is merely the term for a body's relative change in position with respect to its surroundings. Only physical quantities can have direction. Physical quantities being only the vector quantities.

Change in position of a body relative to another body or with respect to a frame of reference or coordinate system is the cause of motion.
vector representing a change in position of a body or point with respect to a reference point, Displacement may be linear or angular.
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.
