weight loss, scales are the most popular method used to gauge weight-loss success. A scale measures the sum of your total body weight. Body weight fluctuates during the day, and from day to day, depending on a. variety of factors.
Q: If the velocity of an object is changing, its momentum is also changing. A: TRUE. If the velocity of an object is changing, its momentum is also changing. Expert answered|jeifunk|Points 13479|. Log in to see link for more information.
An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in a closed system does not change with time, as described by the law of conservation of momentum. As there is no absolute frame of reference, absolute motion cannot be determined.
