If the position of a body is not changing with respect to a given frame of reference (reference point), the body is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position with reference to its surroundings. An object's motion cannot change unless it is acted upon by a force, as described. Momentum is a quantity which is used for measuring the motion of an object. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in an isolated system (one not affected by external forces) does not change with time, as described by the law of conservation of momentum.
